HL100M (formerly HL4M)
The Godwin Dri-Prime 4" x 4" (100mm x 100mm) HL4M automatic self-priming centrifugal pump is a compact, high pressure pump perfectly suited for temporary pumping under discharge pressure conditions or high discharge lifts. Capable of generating maximum flows of 1,000 gallons per minute (63.1 l/sec.) and discharge heads to 455 feet (138.7M) or 195 psi (13.4 BAR), the HL4M is 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 HL4M 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 455 feet (138.7M), maximum flows to 800 gpm (50.5 l/sec.).
- Pumpend available in cast iron, stainless steel and other hardened materials.
- Extensive application flexibility — will handle sludge with solids up to 1-3/8" (35mm) in diameter.
- Continuously operated “Godwin” venturi air ejector priming device featuring direct drive air compressor requiring no periodic adjustment or control.
- Dry running, oil-bath, mechanical seal with high abrasion resistant silicon carbide interfaces.
- Solids handling swing-type Non Return valve with renewable flexible rubber seat.
- Compact unit mounted on a heavy-duty 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 — John Deere 4045T. Available with a variety of engines including Caterpillar and Deutz. Electric motor driven units are also available.
- Low-profile side discharge for easy pipe connection.
- A variety of silenced units are available.
