Diaphragm pumps operate on natural gas or compressed air
Graco
This company’s recently expanded line of Husky 1050 natural gas-operated, 1-in. (25-mm) double-diaphragm pumps (photo, p. 23) operate safely on natural gas or compressed air. They are designed for the midstream and upstream oil-and-gas markets. These pumps can transfer low-, mid- and high-viscosity fluids, and are designed to withstand deadhead and dry-run conditions with no damage to the pump or surrounding equipment, says the manufacturer. They provide flowrates to 50 gal/min (379 L/min) and pressures to 100 lb/in 2 (6.9 bars). — Graco, Inc., Minneapolis, Minn.
