Pleuger plunger pumps are positive displacement pumps which provide a constant volume flow independent of the pressure and are used in almost all applications.
Each series of the vertical plunger pumps is designed to withstand high loads and ensure reliable operation. Many pumps are designed on special customer request based on their specifications for use in demanding special applications.
Pump cylinders with a minimum of clearance volume are the economical solution for the pumping of liquid gases such as ammonia, CO2, LNG and LPG. The minimization of the clearance volume is an essential method in the pumping of compressible media, where the compressibility factor has a significant influence on the volumetric efficiency of the pump. This applies not only to process pumps, but also to reinjections into caverns and oil fields.
