The combination of FMI rotary piston pump and Ismatec drives results in a range of pumps (photo) for very accurate and reliable dispensing, even when highly aggressive chemicals or viscous media need to be transferred. The pump heads are available with ceramic pistons and ceramic cylinder heads. There are no valves to clog, leak or maintain, and the piston is the only moving part. Drift-free operation (±1% from set point) is provided with flowrates from microliters per minute up to 2.3 L/min with positive displacement pumping up to 6.9 barg. Control options include RS232 and analog interfaces. — Michael Smith Engineers Ltd., Woking, Surry, U.K.
