Ceramic Pumps

These ceramic pumps feature a unique valveless rotating/reciprocating piston design that eliminates the need for check valves, which can clog, leak, or fail over time. The result is maintenance-free, drift-free fluid control that will hold an accuracy of ±1% or better over millions of cycles. In addition, the pumps’ process parameters can be easily changed — flowrate can be infinitely controlled either mechanically or electronically via standard industrial-control protocols. Flow control is viscosity-independent for added flowrate stability. Models are available to dispense as little as 5 µL per stroke up to 4 L/min for continuous metering. The pumps are suitable for routine metering of monomers, catalysts, food additives, acids, extraction solvents, alternative fuels, water treatment chemicals, and even viscous fluids and slurries.
