Duplex pumps are designed to offer precision mixing, diluting, and proportional metering for OEM medical, analytical, and industrial instrumentation.The pumps consist of two valveless pump heads direct coupled to a single variable speed drive, with a standard 23-frame stepper motor although other drive types can be used. The displacement of each pump head is independently adjustable, and a variety of pump head sizes can be used in combinations to achieve dispensing ratios from 1:1 up to 500:1. The pumps use the manufacturer’s valveless piston pump technology which uses one moving part, a rotating and reciprocating ceramic piston to accomplish both pumping and valving functions without valves.
