Quiet. Robust. Maintenance-friendly.

Download datasheet

The P-Series of air-driven pumps reduce maintenance downtime and provide reliability for pumping various liquids with pressure up to 72,500 psi (5,000 bars). The pumps operate with an automatic reciprocating differential area piston principle. They are available as single-acting and double-acting types which provides for a significant range of outlet pressure and flow rate combinations for applications in the oil & gas, automotive, gas processing, hose manufacturing, and other industrial sectors. The P-Series pneumatic pumps can be ATEX certified and are used for pressurizing liquids for burst testing, charging, bolt tensioning, and other high pressure applications.

Benefits & Features
Minimize maintenance time by replacing check valves in a few minutes
It is simple to convert a single acting pump into a double-acting pump in case of extra flow capacity is required
Improved cycling speed because an air-cycling valve is mounted directly on top of air cylinder providing less frictional resistance
Reduction of noise level due to less frictional resistance of air-cycling valves instead of mechanical pilot
Freezing of the pump is avoided through an air cycling valve containing a lightweight spool to provide high airflow at low air velocity
Suitable for use with water because all wetted parts of the high pressure pump section are made of special selected stainless steel
Increased lifetime of seals by using specially developed U-PE seals that provide optimum plunger sealing for many mediums
Minimized downtime by reducing time of high pressure seal change with the pump design focusing on simple dismantling of air-drive section
Safe operation is realized through packing release holes that prevent liquid to escape from the hydraulic section to the air drive section
