Product Description:
The S 35 PU is a pneumatically driven, single-acting piston pump that operates on the pressure intensification principle with a pressure ratio of 34:1. It consists of a pneumatically actuated drive part and a high-pressure part linked by a piston rod. The design ensures isolation between the drive and high-pressure parts to prevent leakage into the pneumatic drive. The pump is constructed with high-tensile stainless steel piston rods and tempered steel valve seats, with PTFE sealings for wear resistance.

Application:
The PERFORATOR S 35 PU Injection pump is designed for smaller companies focusing on building refurbishment. It can handle common injection materials with a mix ratio of 1:1.

Additional Information:
Engineering and design are subject to change within the specified technical features and performance data. General terms and conditions, including product liability, apply exclusively.

Catalog excerpts

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 sealings of wear resistant PTFE. Application: The PERFORATOR 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.
