General Information

Pneumatic Piston Injectionpump GX 45 PU

The pressure injection pump GX 45 PU is a pneumatically driven, single acting piston pump, operating acc. to the pressure intensification principle. The area ratio of drive pressure to pressure piston ring area shows the pressure ratio which is 45:1 for GX 45 PU pumps. 

The pump consists of a pneumatically actuated drive part and a high pressure part, which are connected by a plunger. Two parallel fitted high-pressure pistons at the end of the plunger are connected via yoke. Thus, the drive and high pressure parts are isolated, which prevents that pump medium could get into the pneumatic drive part in case of leakages of the high-pressure sealing.

The plunger is made of high-tensile stainless steel and is distinguished by long service life. The valve seats are of tempered steel and the gaskets are of wear-resistant PTFE.
