The pressure injection pump Type S 35 PU is a pneu- matically driven, single acting piston pump that operates after the pressure intensification principle. The area ra- tio 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-pres- sure 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 seal- ings of wear resistant PTFE.
Application: The S 35 PU Injection pump is especially designed for smaller companies with the focus on the refurbishment of buildings.
The pump can handle most of the common injection materials with a mix ration of 1:1.
