Suncenter air driven liquid pump,hydro/hydraulic/hydrostatic pressure test pump

Air Driven Liquid Pumps-DGG Series

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

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

2. 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:

l   Pressure testing

l   Work holding/power clamping

l   Jacking/lifting

l   Valve actuator control

l   Hydraulic cylinder actuation

l   Press safety overload devices

l   Roller tensioning

l   Metering

l   Precision lubrication and spraying

l    Liquefied gas transfer

DGG Series Liquid Pumps(Single acting, single air drive head)
l DGG pumps have aluminum bodies and wetted materials of stainless steel or carbon steel ,which depends on different service liquid. Materials of stainless steel, make them an excellent choice of water/oil/liquid application. High quality seals, long service life available.

l Rustproof and beautiful blue appearance with oxidation treatment applying to aluminum parts.

l S est operation pressure be not above 8 bar so as to protect pumps for long life durability.

l Drive air of 7 bars delivers approx.15% more flow at 6 bar. Drive air of 5 bar delivers approx.15% less flow at 6 bar

Suncenter DLS Series Pneumatic (Air driven) hydraulic pressure test bench 

SUNCENTER- Hydraulic test benches are compact and delicacy solution tailored to customer specific requirements with air driven liquid pumps as well as all accessories to be fitted and installed on the frame or in closed cabinet.

To operate this system, the pressure gauges, valves and pressure regulators have to be fitted on panels. The outlet pressure is easily to be set through a simple air regulator. The pump stops automatically when this end pressure is reached and restarts with a slight drop in the outlet pressure or an increase in the air drive pressure. SUNCENTER Hydraulic power packs are available with wide range of pressure ratios make these series of pumps ideal for powering a variety of oil/hydraulic operations. The maximum operating pressure up to 640 MPa. 

As the pressure will be generated by means of a pneumatically operated pump，the electric connection will not be necessary. To operate this system, the air driven liquid pump have to be equipped with the air control unit combined filter and water separator, pressure-regulating valve, pressure control gauge as well as manual relieve valve. In this operation, the pump will be mounted to the stainless steel tank in the closed cabinet in a compact and space saving manner. Pressure gauges, valves and pressure regulators will be fitted on panel. 

The desired operating pressure can be attained by adjusting the driving air pressure. When the driving air pressure and the output pressure reach the balance, the pump stops filling pressure and the output pressure stays at the preset value. This hydraulic unit can be used for all kinds of pressure testing and test tools for research and test institutes or for other functions requiring a determined pressure.
