Cylinder Filling Pumps 


These 1" motor speed pumps have long been popular for 

cylinder filling, small volume motor fueling & supplying small 

vaporizers. They offer the same heavy-duty construction of 

larger Blackmer models. Available in two mounting styles & 

capacity ranges. 

C-Face Mounting — Direct Motor Drive 

Pumps in the LGF Series mount directly to standard C-Face, 

1750 rpm motors with flexible coupling. LGF1 pumps use a 1 hp 

motor as standard and LGF1P pumps use a 1 1 ⁄2 hp motor as 

standard. Standard motors for these pumps are single-phase, 

115/230 volt, right-hand rotation, explosion-proof construction, 

with automatic reset thermal overload protection. U.L. listed & 

suitable for continuous duty. An explosion-proof manual switch 

is also available for mounting either at the motor or at a remote 

location. 

Base Mounting — Direct Motor Drive 

LGB1 Series pumps have brackets for foot-mounting to a conventional 

baseplate. The mounted pump is furnished with a 

flexible shaft coupling for connection to a standard motor. These 

units are designated as LGB1-DM or LGB1P-DM. Motors for 

these units are shipped to customer specifications. Coupling 

guard included.

Built-In Combination Valve Eliminates 

Cost Of Separate Bypass Valves 

Built into the LGF1 & LGB1 Series pump is a patented 

“combination” valve acting as a back-to-tank bypass valve & 

as an internal relief valve. This feature lowers installation costs 

by 

eliminating the need for a separate bypass valve. It also 

assures pressure relief if the back-to-tank bypass line is 

closed. The valve’s unique three-stage operation is illustrated 

to the right. 

Normal Operation 

Valve completely closed 

during normal operation 

with discharge line open. 

Combination Relief/Bypass Valve 

Back-to-Tank Bypassing 

Discharge pressure exceeding 

the valve setting opens valve to 

second stage, returning all or 

part of flow back to supply tank. 

Pressure Relief 

If back-to-tank line is 

closed, valve opens to 

third stage, passing flow 

back to inlet side of pump.

Stationary Bulk Plant Pumps 

Multi-Purpose Pumps For Bulk Plants, 

Terminals & Truck Systems 

These workhorse pumps have long been popular for a broad 

range of service on bobtails, transports, vaporizers and bulk 

transfer service. The LGLD2 and LGLD3 are particularly suited 

to bobtails, because they offer a double shaft extension. This 

permits use of the pump by either right or left handed PTO 

rotation simply by reversing the position in which the pump is 

mounted. 

The LGLD2/LGLD3 pumps are designed for medium volume 

bulk plant service and transfer applications. They feature a 

single-shaft configuration - especially suited for stationary applications. 

Models in these series are fitted for either LP Gas or anhydrous 

ammonia service. All of the pumps are equipped with replaceable 

cylinder liners and end discs, permitting rebuilding of the 

pump to like new conditions. 

High Capacity Liquefied Gas Pump 

Blackmer’s LGLD4 pump is fitted with a special cavitation suppression 

liner for optimum performance & extended service life. UL listed for 

handling butane, propane & anhydrous ammonia, this durable pump is 

ideal for rapid loading & unloading of transports and bobtails or bulk plant 

service. Flow rates range from 130 to 270 GPM with differential pressures 

up to 125 psi. 

LGLD2 & LGLD3 Pumps 

Capacity Range: 18 to 140 GPM 

V-Belt Drive Style Pumps 

These units have high torque V-belts and quick disconnect 

sheaves. Sheaves are thinner, which puts 

them closer to the bearings, reducing the stress on 

both motor and pump shafts. Sheaves and hubs are 

a two-part assembly that comes apart easily. Units 

come complete with belt guard pump mounted to 

base plate, and a motor.

SC-Series Side Channel Pump 

Side Channel pumps are used in LPG applications where high differential 

pressure is necessary or low NPSH conditions exist, such as pumping 

from underground tanks, the SC-Series multistage side-channel is the 

pump of choice. 

The Side Channel pump is offered in six different sizes, each ranging from 

one to eight stages. This provides for a wide range of pressures, 

capacities, and liquid transfer rates. 

The Corken SC-Series pump line utilizes an integral centrifugal and side 

channel design to create flow characteristics which enable the pump to 

handle up to 50% vapor and low NPSH conditions. The multi-stage 

modular side channel design which features one to eight open radial-vane 

impellers is capable of building differential pressures of over 200 psi. The 

Side Channel pump casing comes standard as Ductile Iron with an option 

of Stainless Steel. The impeller material comes standard as Brass but can 

be ordered as either Steel or Stainless Steel.

Truck Pumps 

Blackmer Flange Mounted Pumps for 

Bobtails and Transports 

For Bobtail Service 

The TLGLF3 pump series flange mounts directly to the truck 

tank in combination with a flanged internal control valve. 

Because it eliminates the intake line and related restrictions to 

flow, it also eliminates the vaporization problem caused by 

them. That means longer pump life and higher effective pump 

capacity. The pump is rated to 125 psi differential. 

The TLGLF3 pump is suitable for both LP Gas and anhydrous 

ammonia. A double shaft extension is standard, making the 

pump suitable for either right or left-hand PTO rotation. The 

pumps is equipped with replaceable cylinder liners and end 

discs, permitting rebuilding of the pump to like-new conditions. 

For Transport Service 

The TLGLF4 series transport pump is designed to mount to 

4" internal valves. It is suitable for both LP Gas and anhydrous 

ammonia service. Ideal intake conditions assure 

maximum pumping rates and the shortest possible transport 

turnaround time. An auxiliary intake port next to the mounting 

flange can be used for emergency unloading of another tank 

or transport. Rated for differential pressures to 125 psi, the 

pump has twin discharge ports which permit the use of two 

hoses, if necessary to reduce pressure loss when unloading 

into restrictive receiving systems.

The chart shows approximate delivery rates as seen in 

vapor equalized propane systems at 70°F (21°C) with no 

pressure loss in pump suction piping. The following will 

cause increased vaporization of the liquid in the pump 

suction, adversely affecting the delivery. 

1. Restrictions in the suction piping such as internal valves, 

excess flow valves, elbows, etc... 

2. Restriction or lack of a vapor return line. 

3. Temperatures below 70°F (21°C). 

This loss of delivery is not caused by the pump but is a 

result of the natural thermodynamic properties of liquified 

petroleum gases. See the GUIDE TO CORKEN LIQUIFIED 

GAS TRANSFER EQUIPMENT CP226 for a complete 

description of these phenomena.

Pump System Troubleshooting Guide 

➝ 

Introduction 

Most LP Gas & anhydrous systems use pumps to move liquid from 

one location to another. Unloading transport trailer tanks into plant 

storage, loading delivery trucks, filling bulk tanks, engine fuel tanks, 

portable cylinders, etc. & pressurizing LP Gas vaporizers are only a 

few applications. A well-designed & properly installed pumping 

system will perform well for some time, but eventually problems occur 

requiring attention. 

Determining the problem and fixing it will take time and be confusing, 

unless one knows clearly how to proceed. The purpose of this 

technical guide is to provide simple, guidelines for correcting LP Gas 

& anhydrous ammonia pumping difficulties. 

The procedure includes a preliminary checklist to help find out if the 

problem can be fixed without taking anything apart. Then, it shows 

how to zero in on more serious problems by using a few pressure 

gauges to pinpoint the cause. 

Before trouble occurs, equip the pumping system for easy pressure 

gauge installation. Small manual shutoff valves can be installed at 

proper locations, with plugs inserted in the outlets. This allows simple 

placement of pressure gauges without removing the LP Gas or anhydrous 

ammonia from the system at the time trouble occurs, saving a 

lot of time and money. Pressure gauges should be installed temporarily 

when the system is first installed, and pressure readings recorded 

while the system is working properly. Then, in many cases, comparing 

pressures with original readings may tell what the trouble is. 

NOTE: Figure 1 shows where pressure gauges should be installed and 

provides blank spaces to record pressure gauge readings from the 

original tests. 

The pressure gauges should not be used continuously, because vibrations 

and the ravages of weather cause their damage or ruin. Therefore, 

as soon as the initial tests are complete, it is best to close the 

shutoff valves, remove the gauges, plug the valves and keep the 

gauges in a safe place, ready for troubleshooting when really needed. 

Diagnosing a problem is easier if the original test results are available, 

but not essential. It requires more time and effort. 

Be sure to obtain and keep available for quick referral the Manufacturer’s 

Operation and Service Manuals for the valves, pump, meter and all 

operating equipment in the system. To avoid delays, maintain a 

complete stock of recommended spare parts on hand for quick 

repairs. 

Follow the steps as shown. Don’t assume the answer is known 

beforehand, or skip any applicable steps. Rather, be thorough and methodical, 

and in most instances, you will solve the problem. On the 

other hand, if you have done all of this and still haven’t worked out your 

problem, feel free to call Gas Equipment Company or Engineered 

Controls International, Inc. direct. We will do our best to help. Perhaps, 

between us, we will be able to solve your problem and add something 

new to the procedure which could help everyone in the future.

The trouble is most likely in the inlet line. It could be: 

1. The pump may be running at a speed too low to develop differential pressure. 

2. An inlet strainer is clogged. 

3. A valve is partially closed somewhere in the inlet time. 

4. Ice has formed either in the bottom of the supply tank or somewhere in the inlet line. This is 

common particularly when the tank has been hydrostatically tested or purged with steam & not 

completely drained & dehydrated. 

5. If a Flomatic valve is used, it may not be opening for a number of reasons: 

a) Pressure in the tank to be filled may be considerably less than that in the supply tank, 

making it impossible for the pump to develop sufficient differential pressure to open the 

valve (simply throttle a manual valve on the discharge line to cause the pump to develop 

enough differential pressure to open the Flomatic valve. As the pressure in the tank to be 

filled goes up, it will be possible to re-open the valve in the discharge line.) 

b) The pump by-pass valve may be blocked open or have broken or damaged parts, 

preventing the pump from developing sufficient differential pressure to open the Flomatic 

valve. (Pump outlet pressure must rise at least 21 PSI to open the Flomatic valve.) 

c) The Flomatic strainer, filter, three-way valve or other element in the actuating line is clogged, 

or the activating line is kinked. 

d) The Flomatic valve internal parts may be damaged or worn. (Refer to Rego installation 

manual #A7884F-301 for flanged valves or #L-451 for diaphragm-type threaded valves for 

repair instructions.) 

6. If an internal valve is used, the main valve may not be opening due to insufficient equalization time, 

broken or damaged valve parts, valve lever in closed position or insufficient excess flow sizing. 

NOTE: Meter pressure is not needed for this condition.

The trouble is most likely related to the pump or 

by-pass valve. It could be: 

1. The pump may have excessively worn parts. 

2. The internal by-pass valve in the pump may be 

blocked open by foreign material, or may have broken 

or damaged parts. 

3. The back-to-tank by-pass valve may be blocked open by 

foreign material or may have broken or damaged parts. 

4. The manual by-pass valve, if so equipped, may be open. 

NOTE: Meter pressure is not needed for this condition.

Pump System Troubleshooting Chart 

Basic Assumption 

The pumping system did work OK, but now the transfer rate is 

considerably less, or the system won’t pump at all. 

Preliminary Review 

1. Check the supply tank liquid level. The transfer rate could be considerably 

reduced if the level is low, due to bubbles in the line, because of insufficient liquid 

head, or a vortex effect in the tank. Remember, reduction in the pumping rate 

from these causes will be more extreme in cold weather (tank pressures are low). 

2. Examine the pump drive to make sure the pump is rotating properly. Inspect for 

loose drive belts, damaged or broken flexible couplings or universal joints, 

broken drive keys & damaged or inoperative power take-off or pump clutch, etc. 

3. If the system is equipped with the Rego Flomatic Valve. 

a) Three-way valve handle should be straight out, allowing the valve to open. 

b) Check the position indicator on the Flomatic Valve when the pump is 

running. If the indicator shows that the valve is open, the trouble must be 

downstream of the valve. 

c) Make sure the priming valve is open, allowing pressure to equalize between 

the tank and pump inlet. 

4. If the system is equipped with internal valves, make sure the operating lever 

moves to a full open position. Repair if needed. 

5. Make sure all valves in the system are either open or closed as required for 

normal operation. Check each valve in sequence, starting from the supply tank, 

making sure that no valve element is missed. 

If the cause of the problem has not been determined during preliminary review, it 

will be necessary to conduct diagnostic tests, using pressure gauges at key points 

in the system. 

Diagnostic Tests 

Open all valves as required for proper pumping operation. Gauges should 

show tank pressure, pump inlet pressure, pump outlet pressure and meter 

pressure to be equal. 

Start the pump and observe all pressure gauges. Match results with conditions 

A, B, C, or D. Follow the appropriate steps. 

Final Results 

Make repairs or adjustments as needed, and test the system’s operation. 

Record a new set of test pressures for future reference, and other replacements 

for all space parts used. The system now is ready to return to service.

The trouble is most likely in the meter vapor eliminator or meter differential 

valve. It could be: 

1. The meter’s vapor eliminator may be malfunctioning. If the valve at the 

outlet of the vapor eliminator does not seat when the vapors have been 

purged, the differential valve downstream of the meter will not open. Such 

failure could be caused by a damaged vapor eliminator valve seat, foreign 

material blocking the vapor eliminator valve, a leak in the ball float, or a 

jammed or binding linkage between the ball and valve. 

2. The diaphragm could be ruptured, or other parts could be damaged or broken 

in the differential valve downstream of the meter.

The problem is probably downstream of the pump. Look for a closed valve, 

or some type of blockage in the discharge line. It could be: 

1. The meter strainer may be clogged. 

2. A back check valve at the inlet of the meter may be blocked, closed, or jammed. 

3. The meter rotor may be jammed by foreign material, preventing it from moving 

properly, which would prevent or retard flow. 

4. The drive key on the meter gears may be sheared. (In this case, flow would 

actually be moving through the meter but not registering.) 

5. The differential valve downstream of the meter may be closed due to damage, 

foreign material or ice. 

6. If screw type hose fittings are used, it is extremely important that they be 

installed properly. If not, it is possible that a flap of rubber may be cut from 

the inside diameter of the hose, acting as a back check. It can flap across the 

discharge line, effectively stopping the flow. 

7. Check the hose nozzle valve, if so equipped. In some brands, a bent handle 

or other defect may prevent the inner valve from opening sufficiently to allow 

a proper amount of flow. 

8. The problem could be in the valve assemblies in the tank to be filled. If you 

are dealing with a delivery truck application, move to another tank and see 

whether the problem still exists. If not, it may be a problem with one specific 

tank, rather than the pumping system. 

9. Some delivery trucks are equipped with a quick-acting valve immediately 

upstream of the hose reel. Make sure that this valve is open. 

10.Some delivery trucks are equipped with excess flow valves between the 

meter & hose reel. Improper sizing, a weak spring, or other valve damage can 

cause this valve to close prematurely, effectively stopping the flow. 

11.If, with a delivery truck system, the flow reduced considerably while the tank 

is being filled, it is possible that the back-to-tank by-pass valve is not set high 

enough to compensate for vapor pressure buildup in the tank being filled. This 

can be solved merely by adjusting the by-pass valve at a slightly higher level. 

WARNING: Do not raise the back-to-tank by-pass setting high enough to cause 

the internal relief valve in the pump to actuate. Excessive cavitation, loss of 

capacity and premature pump wear can occur. 

Final Results 

Make repairs or adjustments as needed, and test the system’s operation. 

Record a new set of test pressures for future reference, and other replacements 

for all space parts used. The system now is ready to return to service.

** Compression Ratio defined as absolute discharge pressure divided by 

absolute inlet pressure. 

*** Compression Ratios are limited by discharge temperature. High compression 

ratios can create excessive heat, i.e. over 350°F (117°C). The duty cycle 

must provide for adequate cooling time between periods of operation to 

prevent excessive operating temperature.

Tank car vapor recovery system 

If, for example, after the liquid transfer phase of the unloading 

operation is complete, the vapor pressure reads 150 psig, 

there would be approximately 1315 gallons of LP Gas in vapor 

form remaining in the tank car. Of this, 845 gallons can be 

economically recovered in less than three hours. 

* Physical properties based on NFPA #58 data for commercial propane. 

** Economically recoverable product based on reduction of tank pressure to 

25% of original value. Residual liquid not included.

Drum Hydrapak Hydraulic Cooler 

Hydraulic Drive Systems provide an alternative to drive shafts for 

operating cargo pumps. Hydraulically driven pumps that require 

extended use, such as unloading a transport, would not be 

possible with a standard 30-40 gallon oil reservoir used in intermittent 

duty due to the lack of heat dissipation. The Drum 

Hydrapak oil cooler makes this possible. 

A hydraulic oil cooler acts like a radiator on an automobile. As 

the oil passes through the radiator, a high volume fan cools the 

fluid making it possible to extend the duty cycle of the rotating 

equipment. 

Features 

• Heavy Duty 316 Stainless Steel Main frame 

• Corrosion resistant aluminum radiator 

• Incorporates a standard spin-on design filter 

• Cooling fan driven by a high performance hydraulic motor 

• Light weight (MH1, 49lbs.; DH3, 110lbs.) 

• Filter restriction indicator monitors filter element condition 

Benefits 

• Eliminates PTO shaft and universal joint maintenance 

• Close coupled hydraulic motor and cargo pump eliminates poor alignment 

• Safer operation due to the elimination of exposed rotating equipment 

• “Soft Start” transmission of power produces prolonged service life of 

cargo pumping system 

• Minimal maintenance is required - oil and filter changes twice a year 

•Truck and trailer alignment is not a concern 

• Hydraulic controls can be placed at convenient locations for clear 

view of unloading hose 

• Hydraulic fluid will internally bypass if a mechanical problem occurs 

eliminating damage 

• Small amount of hydraulic fluid is needed (MH1, 2 gal.; DH3, 3.5 gal.) 

• Built in the USA

Pump Installation 

Quick Reference Guide For Trouble Free Operation 

Make sure you are thoroughly trained before you attempt any pump installations. 

Improper conditions or procedures can cause accidents resulting in property damage and personal injury. 

ALWAYS FOLLOW ORIGINAL EQUIPMENT MANUFACTURER’S GUIDELINES. 

Inlet Piping 

Discharge Piping 

PUMP LOCATION 

•Underneath and as close to the 

supply tank as possible. 

•Inlet to the pump is very 

important. 

•A differential by-pass valve must always be 

installed in a pumping system. 

•Can use smaller piping on discharge side of 

the pump - watch total distance from pump 

to filling point. 

INLET PIPE SIZE 

•Same as pump inlet connection or 

one pipe size larger. 

INLET PIPING 

Use full port ball valves. 

•Use strainer on inlet 10X pipe 

diameter from pump inlet 

•Last valve, fitting, elbow should 

also be 10X the pipe diameter 

away from the inlet 

•Use a soft seat back check 

valve in discharge lines 

longer than 50 feet 

located just past the back 

to tank by-pass valve. 

•If using a reducer at the pump 

inlet, use an eccentric reducer flat 

side up. 

•When using a piping tee off 

a supply line, come off the 

bottom of the piping for liquid. 

•By-pass valve should be 

piped back to the vapor 

section of the storage 

tank and set at least 25 

psig lower than the pump 

internal relief 

setting. 

•Have inlet piping slope 

downward towards the 

pump inlet. 

•The by-pass return line 

should be level or go up 

to the tank and should 

not be restricted. 

•Use separate liquid lines to 

supply each pump when 

using more than one pump at 

one time.
