Piston Metering Pumps

Valveless Piston Metering Pumps provide precision fluid control for environmental monitoring, sampling, & treatment applications. The low current DC motor is ideal for extended 12/24 Volt battery operation in remote locations. The unique design of the CeramPump utilizes one moving part, a rotating and reciprocating ceramic piston to accomplish both pumping and valving functions without valves. The piston and mated liner are made of dimensionally stable, sapphire-hard ceramics that ensure long term, drift-free accuracy of 1% or better for millions of maintenance-free cycles.
