High-Precision Reciprocating Metering Pumps
reciprocating METERING PUMP of high precision
The Kistone P series metering pump is a reciprocating pump in which the pumped liquid is displaced by a piston. This means that the piston and piston seals are in direct contact with the liquid. Thanks to this technology, WRS offers a cost-effective solution for simple dosing tasks with a flow rate of up to 3000 l/h and an outlet pressure of up to 500 bar. WRS sealing technologies for reciprocating pumps allow injecting liquids into processes with a high degree of discharge accuracy at high pressure without leaks.
