HL200M (formerly HL6M)
The Godwin Dri-Prime 8" x 6" (200mm x 150mm) HL6M automatic priming centrifugal pump is a high pressure discharge pump with maximum flows of 2300 gallons per minute (145 l/sec.) and discharge heads to 320 feet (97.5M) or 135 psi (9.3 BAR). At home in a wide variety of applications, the HL6M has been used in temporary fire service, quarry and mine dewatering, and as a temporary replacement for permanently installed transfer pumps. Like all Godwin Dri-Prime pumps, the HL6M can prime and reprime automatically from dry to 28 feet (8.5M) of suction lift.
- Fully automatic priming from dry to 28 feet (8.5M) of suction lift. Maximum heads to 320 feet (97.5M), maximum flows to 2300 gpm (145 l/sec.).
- Pumpend available in cast iron, stainless steel and other hardened materials.
- Extensive application flexibility — will handle sludges and liquids with solids up to 1-1/2" (38mm) in diameter.
- Continuously operated “Godwin” venturi air ejector priming device featuring belt driven air compressor requiring no form of periodic adjustment or control.
- Solids handling flapper-type Non Return Valve with renewable flexible rubber seat.
- Double, high pressure mechanical seal with high abrasion resistant silicon carbide interfaces. Oil bath immersion for dry running.
- Compact unit mounted on a heavyduty skid base or two-wheeled highway trailer both incorporating integral overnight running fuel tank and lifting frame.
- Simple maintenance — normally limited to checking engine and seal cavity oil levels.
- Standard engine — Caterpillar 3126. Available with a variety of engines including John Deere, Cummins and Deutz. Electric motor driven units are also available.
- A variety of silenced units are available
