Annular Gear Pumps Ensure Pulse Free Flow

The Series ML low-pressure and Series MH micro annular gear pumps promise precise and pulse-less flow rate control with the purpose of conserving liquids and increasing efficiency. The components measure as small as 13 mm in diameter by 68 mm in length. Both series use high-precision rotors that provide flow-rate control at differential pressures up to 80 bar. The rotors allow the pumps to dispense volumes as small as 0.25 ml and handle flow rates from 0.15 to 300 ml/min, with accuracies within ±1%. Additionally, gear-tooth-forming technology keeps pulsations to a minimum. MICROPUMP INC., Vancouver, WA. (360) 253-2008.
