Durable liquid nitrogen pump gas supplier for safety valve calibration

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 outlet pressure can be calculated.

SUNCENTER- Liquid gas filling pump systems are compact and delicacy solution tailored to customer specific requirements with air driven 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.

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 pump have to be equipped with the air control unit combined filter, 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.
