General Information

Pneumatic Piston Injection Pumps 35 PU
Description

The pressure injection pump Type S 35 PU is a pneumatically driven, single acting piston pump that operates after the pressure intensification principle. The area ratio of drive pressure to pressure piston ring area yields the pressure ratio which is 34:1 in type S 35 PU pumps. 


The pump consists of a pneumatically actuated drive part and a high-pressure part. Drive part and high-pressure part are linked with a piston rod. Two parallel high-pressure pistons are arranged at the end of the piston rod and are connected via a yoke. Thus, the drive and high-pressure parts are isolated and it is prevented that pump medium gets into the pneumatic drive part in case of leakages in the high-pressure sealing. The piston rods are of high-tensile stainless steel and boast long service lives. 


The valve seats are of tempered steel and the seals are of wear resistant PTFE.
