Ultra-Precise Zirconia Ceramic Plunger Pump With Ceramic Piston Rods
The valveless Ceramic Pump was first patented by Fluid Metering over 55 years ago. Valveless Metering’s pumps, have only one moving part to accomplish both the pumping and valving functions, thereby eliminating the check valves that are present in all other reciprocating (syringe pumps, diaphragm pumps, bellows, piston) designs.
