Description

The  pressure  injection  pump  Type  S  35  SO  PU  is  a  pneumatically driven,  single   acting  piston pump  that  operates  after the pressure in- tensification  principle. The area ratio of drive pressure to pressure piston ring area yields the pressure ratio which is 34:1 in type S 35 SO 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 ser- vice lives.The valve   seats   are  of  tempered steel  and  the  sealings of wear resistant PTFE.

Application: The S 35 SO PU Injection pump is especially designed for smaller companies with the focus on the  refurbishment  of  buildings.  Th  pump  can  handle  most of the common injection materials with a mix ration of 1:1. It is equipped with a stroke-counter, bypass valve and an adjustable pressure switch at the outlet.
