DGM Series Air driven water/liquid/ hydraulic pump


Suncenter Compressed Air Driven Liquid Booster Pump-DGM Series

We offer the most complete range of Air driven liquid pump models in the industry measured for:

A.Capability of ultimate pressure, flow or output horsepower. 

B.Compatibility with a broad variety of liquids, such as oil, water and chemical applications.


SUNCENTER pumps are air driven at a drive air pressure of 2 to 10bar (29 to145 psi) by the normal air compressor. Basically the principle of operation is similar to a reciprocating amplifier where control of the piston at the end position is regulated by a pilot operated 4/2 way valve.

Suncenter pumps feature a large air piston joint to a smaller diameter plunger. The pressure ratio is the difference of these two areas and is the method of determining maximum outlet pressure. Higher pressures obtained by using higher pressure ratios.Suncenter model numbers reflect the pumps nominal pressure ratios, while the technical data indicates exact ratios. The outlet pressure is easily to set through a simple air regulator. By multiplying the pressure ratio by the available shop air pressure, the nominal liquid pressure can be calculated.


SUNCENTER pumps are self priming. In general it is not necessary to use an air line lubricator. The liquid to be pumped flows into the suction chamber by the up-stroke of the drive piston. By this suction effect, the inlet check valve is opened and the outlet check valve is closed. The down-stroke generates the pressure at the liquid side. The inlet check valve is closed and the outlet check valve is opened by the generated pressure. SUNCENTER liquid pumps cycle automatically, where the pressure is built up the numbers of cycles slow down, the pump stops automatically when the output pressure forces are equal. The pump restarts with a slight drop in the outlet pressure or an increase in the air drive pressure. Pump performance can be affected by a number of conditions, such as freezing of muffler or pilot valves (which is caused by moisture in air lines), inadequate inlet air line sizes and dirty filers. Don’t reduce the indicated port sizes and consult SUNCENTER for exact flow conditions not shown in charts.


Applications include:


·Pressure testing

·Burst(Hydrostatic) testing

·Work holding/power clamping

·Jacking/lifting

·Valve actuator control

·Hydraulic cylinder actuation

·Press safety overload devices

·Roller tensioning

·Metering

·Precision lubrication and spraying

·Liquefied gas transfer


Key features include: 

·Compressed Air driven - no electricity required (connect to normal air compressor)

·In order to extend the lifetime of the pump, the driving air pressure should not be higher than 8 bar

·No airline lubricator required 

·Pressures to 640Mpa (6400 bar)  

·Wide range of models with different ratios

·Built-in-cooling on most models 

·Easy to install, operate and maintain

·Best price / performance ratio 

·No heat, flame or spark risk and explosion proof 

·Automatic pressure holding, whatever the cause of the pressure drop, the Suncenter pump will automatically start, keep the loop pressure constant
