Introduction Series PAVC 33/38/65/100 

General Description 

All control is achieved by the proper positioning of the 

swash plate. This is achieved by a servo piston acting on 

one end of the swash plate working against the combined 

effect of the off-setting forces of the pistons and centering 

spring on the other end. The control spool acts as a 

metering valve which varies the pressure behind the 

servo piston. 

As shown in Figure 1, the amount of flow produced by 

the Parker Piston Pump is dependent upon the length of 

stroke of the pumping pistons. This length of stroke, in 

turn, is determined by the position of the swash plate. 

Maximum flow is achieved at an angle of 17°. 

The rotating piston barrel, driven by the prime mover, 

moves the pistons in a circular path and the piston 

slippers are supported hydrostatically against the face of

the swash plate. When the swash plate is in a vertical 

position, perpendicular to the centerline of the piston 

barrel, there is no piston stroke and consequently no 

fluid displacement. When the swash plate is positioned 

at an angle, the pistons are forced in and out of the barrel 

and fluid displacement takes place. The greater the angle 

of the swash plate, the greater the piston stroke. 

The centerline of the pumping piston assembly is offset 

from the centerline of the swash plate. Therefore, as 

shown on the accompanying Figure 1A, the pistons’ 

effective summation force tends to destroke the swash 

plate to a vertical (neutral) position. This destroking force 

is balanced as the swash plate is angled by the force of 

the servo piston.

Control Options Series PAVC 33/38/65/100 

Pressure Compensated Control 

Swash plate angle controls the output flow of the pump. 

Swash plate angle is controlled by the force generated 

against the swash plate by the pumping pistons and by 

the force of the servo piston. The force of the servo 

piston is greater than the force of the pumping pistons 

when both are at the same pressure. 

By means of internal porting, pressure is connected from 

the output port to the servo piston via orifice (E), and to 

the control spool via passage (D). Also pressure is 

applied to the control spool chamber thru orifice (F). As 

long as the pressures at both ends of the control spool 

remain equal, the spool will remain offset upward, due to 

the added force of the spring. 

When pressure reaches the setting of the compensator 

control, the dart leaves its seat causing the pressure in 

the spool chamber to be reduced. The spool now moves 

downward causing pressure in the servo piston cavity to 

vent via port “A”. The reduced pressure at the servo 

piston allows the servo piston to move to the right. This 

movement reduces the angle of the swash plate and 

thereby reduces the pumps output flow. 

As pump pressure on the control spool drops below 

pressure and spring force in the spool chamber, 

the control spool moves upward to maintain an equilibrium 

on both sides of the spool. If pump pressure falls below

compensator control setting, the control spool moves

P Adjustment of PAVC Pumps 

PROCEDURE: 

a. Standard Pressure Compensated Pump 

Pumps are shipped from factory with a differential 

pressure of approximately 150 PSI (10 bar) on PAVC 

33/38/65, PAVC 100 is 300 PSI (21 bar) at 50% of 

maximum swash angle. Differential pressure will 

not normally change through the life of the pump. If 

this control has been tampered with, a close 

approximation of the correct setting can be made as 

follows: 

Dead head the pump (no flow) with a 0-207 bar (0- 

3000 PSI) gauge in the OUTLET (not the low signal 

“B” port), back the pressure compensator adjustment 

out (full counterclockwise). 

The gauge should read between 22-26 bar (325-375 

PSI) PAVC 33, 38 & 65, 34-40 bar (500- 

575 PSI) PAVC 100. If the gauge reads different 

than this, turn the differential adjustment knob 

(Differential Option 4) or add/remove shims (Omit 

Option) until correct pressure figure is reached.

Remote Pressure Control 

Control Type (M) 

Remote control of the PAVC output pressure can be 

achieved by controlling the pressure in the low signal “B” 

port when the pump is set up for Control Type (M). A 

manual, hydraulically piloted, electrical or electroproportionally 

controlled pressure control device is 

installed in the line from the low signal “B” port to tank. 

The pump will then maintain pressure approximately 

equal to the pressure in the “B” port plus the pump 

differential setting. 


This option can be used as an alternative to the load 

sensing option (A) to achieve low pressure standby. 

Minimum standby pressure is somewhat higher than that 

achieved using option (A). In the compensating mode 

there is approximately 1.1 LPM (.3 GPM) flow from the 

low signal “B” port in addition to 3.4 LPM (.9 GPM) flow 

from the control drain port “A”.

Multiple Pressure Standby 

If the pressure level in the low signal “B” port is limited 

by a relief valve, as the desired pump outlet pressure is 

reached, the relief valve in the “B” port will allow the 

pump to standby at a preset pressure. Adding to this 

concept, multiple, remotely piloted relief valves plumbed 

in parallel in the “B” port line can yield multiple, sequential 

pressure settings. 

Electrohydraulic Pressure & Flow Control 

A proportional pressure control valve can be used in 

place of relief valves to give variable pressure control 

proportional to an electrical input signal to the valve. By 

combining this arrangement with a swash plate position 

sensing device, amplifier, and logic circuit, servo control 

of pressure and/or flow is achieved. NOTE: In most 

systems, a load equivalent to the minimum operating 

pressure of the pump cannot be guaranteed. Because of 

this, a sequence valve is required in the discharge line to 

maintain servo flow control. Please refer to ordering 

information section for servo components.

Pressure & Flow Control (Load Sensing) 

Control Type (A) 

Flow control is achieved by placing an orifice (fixed or 

adjustable) in the pump outlet port. The pressure drop 

( P) across this flow control is the governing signal that 

controls the pump’s output, as explained below. 

Whenever the pressure drop at the flow control increases 

(indicating an increase in output flow), the pump attempts 

to compensate by decreasing the output flow. It does this 

by sensing the lower pressure on the downstream side of 

the flow control via line (C), which is balanced against 

the pump pressure via passage (D), on the control spool. 

The control spool is forced down against the control 

spool spring by differential pressure. This vents the 

servo piston cavity, destroking the pump to a point where 

the set pressure drop across the orifice is maintained 

and the flow is obtained. 

The converse of this is also true whenever the pressure 

drop decreases (indicating a decrease in output flow). In 

this case, the control spool is forced up. This increases 

pump displacement in an attempt to maintain the 

predetermined pressure drop or constant flow. 

It should be noted that the pump is still pressure 

compensated and destrokes at the selected pressure 

setting. The pressure compensator control will override 

the flow control whenever the pressure compensator 

control setting is reached.

This arrangement can also be used to provide low pressure 

standby by venting the “B” port through a simple on/off 

valve suitable for flows of 3.8-7.6 LPM (1-2 GPM). When 

flow or pressure is required, this valve is closed allowing 

system pressure to build behind the control spool and 

bringing the pump on-stroke. 

Load Sensing 

If, instead of measuring the pressure drop across the 

orifice in the pump outlet port, it is measured downstream 

of a directional control valve, a constant pressure drop 

will be maintained across the valve spool. This results in 

a constant flow for any given opening of the directional 

control valve regardless of the work load downstream or 

the operating speed of the pump. 

The pump “senses” the amount of pressure necessary to 

move the load and adjusts output flow to match the valve 

opening selected and pressure to overcome the load 

plus the preset P across the valve spool. 

The benefits of this arrangement are that excellent, 

repeatable flow characteristics are achieved, and 

considerable energy savings are realized while metering, 

compared to using a straight pressure compensated 

system.

Pressure & Power (Torque) Control 

Control Type (H) 

The power control is sensitive to the position of the 

servo piston. When the servo piston is to the right, the 

swash plate causes low flow and the power control 

piston develops maximum spring pressure on its 

companion poppet (mechanical feedback). When the 

servo piston is left and the flow is high, the power control 

piston reduces spring pressure on the poppet. This 

allows it to open under less pressure in the control spool 

chamber, thereby venting some of the pressure in the 

control spool chamber. As with the operation of the 

pressure compensator control, this allows the control

spool to move downward, venting the servo piston cavity 

and causing the servo piston to move to the right. This 

reduces output flow and thereby power. 

As indicated in the pictorial drawing, pressure in 

the control spool chamber is affected by both the pressure 

compensator control and the power control. The resultant 

pressure in this chamber is a function of the set points of 

these two controls. Both set points are adjustable.

(5.92) 

NOTES: 

1. Consult factory for information relative to pump option selection 

and additional components required for desired pump function. 

2. For electrohydraulic flow and pressure control of one or two 

pumps, make electrical connections per Figure IV. When one 

pump is used, omit connections to pump #2 feedback. 

3. For electrohydraulic flow only, eliminate pressure command 

signal and place jumper between “Press CMD” and “+10V” 

terminals (compensating pressure will be controlled by 

maximum setting on pump or remote compensator if used). 

4. For electrohydraulic pressure only, eliminate volume command 

signal and place jumper between “VOL CMD” and “+10V” 

terminals or use 801179 pressure driver card. 

5. Figures I thru III show nominal input vs. output relationships. 

The actual values will vary with component tolerances. Full 

volume range will be realized with 0 to 7 volts. Full pressure 

range will be realized with 0 to 7 volts, or 0-500MA. 

6. Pump shown is a clockwise rotation. For a counterclockwise 

rotation LVDT feedback is on opposite side. 

7. For further detail on installation of AP11/AP211, refer to the

Use Of A Relief Valve 

The use of a relief valve, while not mandatory is 

recommended in the main circuit to suppress hydraulic 

shock loads and additional system protection. If a 

minimum volume stop is used, 

the use of a relief valve is mandatory. 

Fluid Recommendations 

Premium quality hydraulic oil with a viscosity range 

between 150-250 SSU (30-50 cst.) at 38°C (100°F). 

Normal operating viscosity range between 80-1000 

SSU (17-180 cst.). Maximum start-up viscosity is 

4000 SSU (1000 cst.). 

NOTE: Consult Parker when exceeding 71°C (160°F) 

operation. Oil should have maximum anti-wear 

properties, rust and oxidation treatment. 

Filtration 

For maximum pump and system component life, 

the system should be protected from contamination at 

a level not to exceed 125 particles greater than 

10 microns per milliliter of fluid. (SAE Class 4/ISO 

16/13). Due to the nature of variable displacement 

pumps, variations in pump inlet conditions, fluid 

acceleration losses, system aeration, and duty cycle 

we do not recommend suction line filters. We do 

recommend the use of a properly sized, in-tank suction 

strainer. Contact your Parker representative for 

assistance. 

Start-Up 

On initial start-up, the case should be filled with oil, 

pressure should be reduced and the circuit should be 

open or the air bled from the pump outlet to permit 

priming. Use of the airbleed is recommended on initial 

start-up. See Installation and Mounting Section to 

connect airbleed. 

Inlet Conditions 

Not to exceed .17 bar (5 In. Hg.). Vacuum at 1800 RPM 

on petroleum base fluids. See recommended speed 

spectrum for specific inlet conditions. 

Shaft Rotation and Line Up 

Pump and motor shaft alignment must be within 

.010 TIR maximum, using a standard floating coupling. 

Please follow coupling manufacturer’s recommended 

installation instructions to prevent 

end thrust on pump shaft. Turn pump to assure 

freedom of rotation. Pump and motor must be 

on a rigid base. 

The coupling should be sized to absorb the peak 

horsepower developed. 

46 

Installation and Mounting 

When a PAVC Series Pump is mounted above the fluid 

level, the position of the “control drain” is not restricted 

but the inlet port should not be on the bottom 

(PAVC100). When a PAVC Series Pump is mounted 

below the fluid level the position of all ports are not 

restricted. The “control drain” should be a separate line 

to the reservoir and extend below the oil level as far 

from the inlet line as possible. The “control drain” line 

can be filtered and/or cooled (must not exceed 7 bar 

(100 PSI) back pressure). Suggested maximum line 

length is 10 feet. 

A built in airbleed is standard on all PAVC 33, 38, 65 

and 100 Pumps. To connect, remove airbleed drain 

plug and connect a line unrestricted to reservoir 

extending below minimum oil level. Back pressure 

in this line must not exceed .28 bar (4 PSI). 

Special Installations 

Consult your Parker representative for any application 

requiring the following: 

Pressure above rated, drive speed above maximum, 

indirect drive, fluid other than petroleum oil, 

oil temperature above 71°C (160°F). 


Not to exceed 1.72 bar (25 PSI).
