Maag Industrial Pumps, part of PSG® and a global leader in positive displacement gear pumps, has announced the release of stainless steel models of its versatile G Series internal gear pumps. These new stainless steel versions are ideal for challenging corrosive applications requiring a durable pump that can move liquids ranging from thin to highly viscous.

G Series internal gear pumps are available in cast iron and stainless steel construction with 38 to 76 mm port connections. Stainless steel models are rated from 10 to 110 gallons/min, and cast iron models range from 15 to 140 gallons/min. Both models are capable of pumping viscosities up to 431,000 cSt. In addition, G Series pumps are interchangeable with up to 95% of internal gear pumps currently available on the market. No changes needed to piping, driver, coupling, flow rates or baseplates.

Operating equally well in both directions, G Series pumps provide a positive, non-pulsating flow with only two moving parts for easy maintenance. The enlarged bearing housing at the rear end of the pump allows convenient drive-end access to the shaft seal and single-point end-clearance adjustment. The pump casing revolves for easy multiple inlet and outlet positioning.
