HL250M
The Godwin Dri-Prime 12" x 10" (300mm x 250mm) HL250M is a heavy duty, fully automatic self-priming pump specifically offered for pumping under discharge pressure conditions or high discharge lift applications. The HL250M offers flowrates up to 5,700 gpm (360 l/sec.), total dynamic heads up to 390 feet (118.9M), and solids handling up to 3" (75mm) in diameter. Like all Godwin pumps, the HL250M includes the Dri-Prime air ejector priming system for fully automatic priming up to 28 feet (8.5M) of static suction lift.
- Fully automatic priming from dry to 28 feet (8.5M) of suction lift. Maximum heads to 390 feet (118.9M). Maximum flows to 5,700 gpm (360 l/sec.).
- Handles sludges and solids-laden liquids with solids up to 2-9/16" (65mm) in diameter.
- Continuously operated venturi air ejector priming system operated by an air compressor requiring no form of periodic adjustment or operator intervention.
- Double, high pressure mechanical seal with high abrasion resistant silicon carbide interfaces. Oil bath immersion for dry running.
- Mounted to a structural steel skid with integral 250 gal. (946 liter) fuel tank and lifting bail.
- Standard engine — Caterpillar 3406C diesel. Other engines available. Electric drive version also available.
