Diaphragm Pumps

Sept. 14, 2006

Miniature liquid diaphragm pumps use brushless dc motors, which are EMI/RFI quiet and compact.

These selfpriming pumps eliminate tubing fatigue or failure, the manufacturer claims. A corrosion-resistant PVDF/FFPM/PTFE envelope handles acids, caustics, and other difficult materials. Pumps feature free-flow from 50 ml to 3 lpm, 16-ft water suction or 33-ft water head pressure. Applications include environmental and medical monitors, analyzers, process samplers, and portable instruments that need low current consumption.
