Air-Operated Double Diaphragm Pump, 1/2 in Ports, 3 GPM

Air operated double diaphragm pump delivers controlled, low-viscosity fluid transfer with a cast iron body built to resist leaks and daily shop abuse. Designed for petroleum, diesel, oil, and similar liquids, it runs on compressed air for reliable operation where electric pumps aren’t ideal. Nitrile diaphragms and a sealed ball valve help keep flow steady while supporting quick changeover and reduced downtime.

Built for workshops and industrial lines that need a rugged pneumatic transfer pump, this unit moves low-viscosity fluids without the complexity of electric motors. The externally accessible air distribution system helps simplify maintenance, while the nitrile diaphragm setup is suited for frequent cycling and typical petroleum and solvent handling. Use it for fluid transfer, drum-to-tank moves, or process support across automotive, mining, coatings, printing, and water treatment. Grab yours today and keep your fluid handling moving.
