History 

The roots of DEMA Engineering 

date back to 1940, when brothers Bela and 

Herman Deutsch joined together to manufacture 

industrial controls and accessories. 

Sixteen years later, after receiving several inquiries from 

chemical manufacturers for dispensing equipment, the 

team capitalized on the industry’s demand for quality 

chemical dispensing equipment. With an initial product 

line consisting of two proportioners, a dispensing pump 

and a few spray guns, the brothers formed DEMA 

Engineering Company. 

Five decades later, DEMA has become a world leader 

in both the chemical dispensing and fluid control 

industries. The company has over 400 employees 

working at five manufacturing facilities worldwide, 

including locations in Australia, the Netherlands, and 

three in the St. Louis, Missouri area. DEMA now 

manufacturers solenoid valves, chemical injectors, 

liquid level proportioning controls, inline strainers 

and a variety of other fluid dispensing systems. 

DEMA’s product components are 

manufactured on state-of-the-art 

equipment, including computer 

controlled machining and turning 

centers and injection molding 

machines. They are then 

assembled and tested in a 

modern dedicated assembly 

facility. This facility has been 

expanded to serve the car wash, 

agriculture, beverage dispensing, 

reverse osmosis, misting, whirlpool, high pressure 

cleaning and dish and laundry machine industries 

worldwide. DEMA continues to introduce new products 

to meet the demands of an ever changing market. 

Despite DEMA’s success and growth, it is still a family 

owned and operated business. Its current leadership 

is the third generation of the Deutsch family active 

in the company, and is continuing the tradition of 

innovation and quality into the 21st century. 

The DEMA Mission: 

To expand our heritage as designers and manufacturers 

of high quality dispensing and fluid control products by 

being the most innovative company in our industry, 

providing quality products with unique features that 

meet or exceed the need of our global customers, and 

doing so in a timely manner at a competitive price.

Solenoid Valves 

There are two basic types of solenoid valves. The most common is the normally closed 

type in which the valve opens when the coil is energized. The other type is the normally 

open valve which closes when the coil is energized. 

These valves are suitable for most industrial applications. They are ideal for water, air, 

light oil, noncorrosive and nonexplosive liquids. Valves are rated for 200ºF/93ºC fluid and 

120ºF/49ºC ambient except for the Mini Valves which are rated for 180ºF/82ºC fluid and 

120ºF/49ºC ambient, (see pages 7-9). The molded waterproof coils have wiring options 

that include a junction box, spade, conduit and din. They have voltage options of 12VDC, 

24VDC, and 24, 120, 208, and 240VAC 50/60 cycle on most models. Component materials 

are available in Buna N, EPDM, Viton, Teflon and Silicone. DEMA offers valves made 

from brass, stainless steel, Celcon, PVC, polypropylene and nylon. Stainless steel seats 

are standard on all pilot piston, diaphragm (except mini series), and high pressure 

valves. Valves may be mounted in any position except with the coil under the valve. 

Listed by Underwriter’s Laboratories, Inc. (except high pressure). 

Construction 

DEMA solenoid valves are constructed to insure long, trouble free life. They employ 

proven design features for reliable performance on all applications. Quality is maintained 

by strict control methods in all phases of production. Detailed testing of every valve 

produced during all phases of production is followed by 100% testing for body and 

seat tightness, electrical characteristics, and valve operation. All DEMA valves are 

manufactured in our Missouri plants. 

Electrical 

DEMA solenoid valves are available in many AC and DC voltage ratings. 

For ease of identification, coils are manufactured with the following lead wire colors. 

LEADS MOLDED SPADE 

12 VDC/24 VDC Black 12 VDC/24 VDC Black 

24/50-60 AC Orange 24/60 VAC Blue 

120/50-60 AC Blue 120/60 VAC Green 

208-240/50-60 AC Red 240/60 VAC Red 

Leads on valves with a conduit boss and flying lead coils are 18” long while coil leads on 

valves with a junction box are 6” in length.

Pilot-Piston Valves 



Operation: The stem and plunger assembly opens the port. 

This releases the pressure on top of the piston, which moves upward 

and opens the main valve port.

Diaphragm Valves 



Recommended for applications that have unfiltered fluid. 

Operation: When energized, the plunger is pulled to the top plug, thus 

opening the small “pilot port” in the center of the diaphragm plate. 

This releases the pressure on top of the diaphragm allowing incoming 

pressure to lift it off the large center port. When de-energized, the 

solenoid plunger is pushed from the top plug by the kick-off spring and 

closes the pilot port. Fluid passes through the diaphragm bleed hole 

until pressure is equalized on both sides of the diaphragm to shut off 

the large port. 

All diaphragm valves have stainless steel seats 


• Suitable for up to 10 psi steam, 240F/115C with Teflon Diaphragm, 

add suffix (T) for Teflon Diaphragm

Application: Water 

All valves have stainless steel sleeves and seats except 453P.

Operation: Same as a pilot operated valve except the pilot port 

is in a separate chamber from the piston. This allows the plunger to 

operate closer to the top plug with more force and consequently 

higher opening pressure.

INJECTORS 

Inline Chemical Injectors for injecting fluids or air into lines 

conveying liquid under pressure. 

The DEMA injector is a jet pump. A liquid under pressure, usually water, enters the injector and accelerates into a jet through the 

nozzle. This high velocity jet creates a vacuum, which causes fluid to be drawn through the suction tube and into the injector. The 

mixture then flows into a diverging (venturi) passage where pressure is recovered as the flow slows down. A portion of the energy 

of the water is imparted to the injected fluid so the reconverted pressure cannot be as high as the pressure supply. In effect the 

fluid is pumped into the water line; the reduction in pressure reflects the energy required to operate the “pump”. 

A minimum 35% pressure drop is required to create the vacuum. 

Advantages of the Injector 

Injectors have no moving parts, nothing to wear out or lubricate, resulting in extremely low maintenance. They are compact, 

needing no foundation or mounting bracket, and can be installed in any position. Injectors require no wiring, are self-priming and 

need no bleeding or filling. Injection rate is simple to set and can be quickly adjusted during operation. There is nothing to drain 

for seasonal shut down. 

General Information 

Standard C series have a molded Ryton knob with a stainless steel metering screw. 

For special requirements add the following suffixes to the model number. 

P: Special C20 stainless steel metering screw for highest corrosion resistance. 

S: Stainless steel knob for high pressures (over 700psi). 

T: Uses metering tip kit. (see page 15) 

All injectors have a check valve to prevent backflow into the fluid container when there is no water flowing or while rinsing. 

An 8 ft. length of flexible vinyl suction tubing with a foot strainer is supplied. 

Application and Selection 

DEMA injector selection must be based on the water flow and pressure at the location where the injector is to be installed. 

DO NOT size the injector by pipe size. If these quantities are known, choose correct model from Tables on (pages 16 and 17). 

If theses quantities are not known, it is permissible to use spray nozzle rating at any pressure for selection. Once an injector 

has been matched to a spray nozzle system, it will continue to function regardless of fluctuations in line pressure, as the 

water flow will also fluctuate in proportion. Flow rating of 40 psi is the basis of the spray nozzle numbering system 

see glossary on (page 21) and is, therefore, most frequently used. Lengthy piping, hose, or other restrictions resulting in 

pressure loss must be added to the rated pressure before selection. 

Injection Capabilities 

Every injector is supplied with a metering screw or metering tips (T) for setting injection rates within maximum and minimum 

capacities shown in Tables. Maximum injections of viscous fluids (above 75cps) can be increased by ordering the high induction 

metering knob kit, p/n 24-56 (page 15). 

NOTE: Three nozzle bushings are supplied with each C series injector for precise sizing of the injector to water flow within the 

ranges shown. The maximum injection quantities can be doubled by using a nozzle bushing one size smaller than specified, 

but the pressure loss will be 50%. If your flow is in the lower third of the GPM range, order the next smallest injector to 

double the injection rate.

(700-3000 PSI or 48-204 Bar) 

Chemical adjustment: 

Metering screw standard on “C” Series injectors (i.e. 204C). 

Metering tips are color-coded orifices of different sizes used to 

proportion the chemical (add a “T” to the model number (i.e. 204CT). 

Tip Kit ordered separately 

Metering knob assembly (bolted onto the body with four screws) 

can be oriented in any direction for ease of access in tight spots. 

Small (1/4 inch barb) and large (3/8 inch barb) metering knobs 

are interchangeable on all inline injectors. 

204C 

208C 

Each injector is supplied with 3 water nozzle bushings (Figure No. 1) 

for precise sizing of the injector to water flow within the ranges 

shown. Nozzle selection is specified in the installation instructions 

included with each injector. All injectors are equipped with a metering 

screw or metering tips”T” to adjust injection rate up to figures shown 

in tables (page 16). 

For applications using caustic or acidic solutions order metering tip 

adjustment and metering tip kit, specify “T” after the model number. 

Metering tip adjusts injection rate instead of metering screw.

TITAN Warewash Dispensers 

Probe and Probeless Operation with Auto-Switchover 

DEMA’s TITAN range of warewash dispensers was developed 

to reduce the number of service calls and create a more 

profitable installation at all types of warewash accounts. The 

unit can be set up in probe or probeless mode, depending on 

the installation requirements. If set up in probe mode, the unit 

will automatically switch over to probeless mode if any of the 

following parameters are met: 

• Shorted probe 

• Open probe 

• Limed up probe 

• Dispenser does not feed for a period of time 

• Dispenser over feeds for period of time 

Once the parameter is met, the unit will switch itself back to 

probe mode. This feature should greatly reduce the number 

of service calls and allow better use of service and sales 

groups’ time. The TITAN is truly a first of its kind; a dispenser 

that will pay for itself.

DEMAMaster TM Probeless Dispensers 

DM-812-PDL-2T 

DM-811-SC-1T 

DEMAMaster Probeless dispensers function using door 

counts, time or speed control to determine the amount of 

detergent and rinse put into the dish machine. The unit uses 

door openings on a door machine or time on conveyor 

machines to determine the amount of detergent. Two banks 

of dip switches inside the dispenser allow user to easily program 

initial charge and recharge times. When using door 

machine mode, dead cycles can be implemented to prevent 

unit from adding detergent each cycle.

HOUSEKEEPING DISPENSERS 

12 

Dilution at Hand TM Dispensing System 

Dilution at Hand dispensers offer the convenience of filling 

spray bottles with one hand and the option of filling a bucket 

or scrubber with on/off control at the end of hose where 

operator is filling. These unique features, along with the 

traditional lever controlled actuation , make Dilution at Hand 

a truly revolutionary dispenser. 

FILL SPRAY BOTTLES WITH ONE HAND: DEMA’s Dilution at 

Hand valve design incorporates many of the positive features 

used with the successful 633 valve but turns the valve around 

180 degrees for a smooth upward movement when the spray 

bottle pushes lever. 

REMOTE FILL AT DISPENSING POINT: Dilution at Hand’s 

patented remote filling option uses a hand held gun operating 

as a pilot valve back to water valve for easy on/off control 

at the end of hose where operator is filling. There are no 

moving parts, just water being moved from the water valve to 

the gun and back. Now, instead of moving your bucket or 

scrubber to the dispenser, take the dispenser to your point of 

use using the remote fill option. 

Dilution at Hand offers both 1 and 4 gallon per minute 

proportioners, Action Gap backflow or Air Gaps, and 

Dial-A-Blend capability. A dispenser can be built to 

meet any desired application.

MixRite Compressed Air Foam Systems allow any length of 

hose installed on the outlet of dispenser. The hose length or 

foam wand nozzle size have no affect on the foam quality, 

which makes these dispensers ideal for foaming applications 

utilizing long runs of hose or pipe.

CHEMICAL INJECTORS 

Chemical Injectors 

DEMA manufactures two different types of injectors, each 

having their own way to control water flow. The C series 

injectors use one of three different water nozzle bushings to 

control water flow and the B series use an external bypass 

knob for controlling water flow. Injectors are available from 

1/8” NPT up to 1” NPT. (BSP threaded injectors available). 

When choosing an injector it is important to size the injector 

according to the application’s water flow, not pipe size. 

Injector metering knobs can be supplied with a metering 

tip option (example 204CT) or metering screw option 

(example 204C).

SprayClean Injectors 

SprayClean Injectors do not include covers, ball valves, or 

any other device to make them a complete system. These 

units include the injector assembly, appropriate spray gun for 

each model and the chemical inlet tubing assembly. These 

are very basic units that may be wall or drum mounted to 

dispense one chemical. 

Model 244C Three-position gun allows user to choose chemical, 

clear water rinse, and off setting at the spray gun. When 

gun trigger is pulled completely, vacuum is drawn in injector 

and chemical is dispensed through spray gun. Releasing the 

trigger halfway to rest against a latch will eliminate vacuum 

draw of chemical and only spray clear water for rinsing.

Special Injectors 

204B 

Model 201CHT 

1/8” brass injector designed to draw up to 1-1 ratio at 1/2 

gallon per minute (2 liters per minute) flow. Ideal for mixture 

of antifreeze and water for windshield washer filling. 

DEMA OFFERS SEVERAL PLASTIC AND STAINLESS STEEL 

INJECTORS FOR CORROSIVE APPLICATIONS. 

Model P203C or P203CT: 

3/8” polypropylene plastic injector with flow rate of 

4 GPM at 40 psi (16 liters per minute at 2.75 bar) 

Model 203BS-2 or 203BST-2: 

3/8” stainless steel injector with flow rate range of 

3 to 9 GPM at 40 psi (12 to 36 liters per minute at 2.75 bar) 

244C 

Model 244BC Slide valve on chemical injector allows user to 

choose between wash and rinse setting. Squeezing the spray 

gun fully open turns the unit on and dispenses either the 

chemical or clear rinse, depending on slide valve setting. 

(This model allows for a harder spray when rinsing compared 

to the 244C model).
