Fluid Metering's valveless, ceramic pumps have proven to be good for pilot plant fluid control. The sapphire-hard internal components of the pumps eliminate accuracy drift typical of pumping systems that rely on valves and elastomers, (flexible tubing and diaphragms), to move fluid through the pump. The pumps provide a valveless rotating / reciprocation 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 for millions of cycles. In addition, Pilot Plant operations require the ability to easily change process parameters including flow rate. The pumps accommodate that requirement as flow rates can be infinitely controlled either mechanically and/or electronically via standard industrial control protocols. Flow control is viscosity independent for added flow rate stability. Pump models are available to dispense as low as 5 µL per dispense up to 4 L per minute continuous metering.
