The Chemical Metering Pump (photo) offers economical and efficient performance when metering low-flow liquids in a wide range of processing applications, including dosing, sampling and metering. The progressing cavity design of the pump results in a smooth flow, free from pulsations and variations in velocity and volume, which prevents material waste or mixture imbalance. The pump features sealed universal joints for longer life, and has no valves to clog, stick or vapor lock. The unit provides pressures to 300 psi and flowrates from 1 to 190 gal/h. The pump is available in bare-shaft, close-coupled, and motorized configurations. — Moyno, Inc., Springfield, Ohio
