Description

Hale’s Qmax single stage midship generates NFPA 1901 rated flows up to 2250 GPM (8515 LPM). The innovative one-piece body allows easier access to the impeller and mechanical seal, minimizes piping requirements and makes routine maintenance easier.

Features

• Generates NFPA 1901 rated flows up to 2,250 GPM (8,515 LPM) from draft
• Performance range of 0 to 3000 GPM based on available engine power and water source.
• Large suction inlets and full flow waterways cut friction loss and deliver maximum pressure at the discharge valves. Low friction losses allow flows of up to 1,500 on 3-inch and 2,600 GPM on 4-inch pump body openings (from a positive water source)
• Designed to use 6” suction Master Intake Valves (MIV) which have no impact to single hose 1,500 GPM rating
• Dual cutwaters. Smooth water flow delivery to the cast pump body with no twists, turns or restrictions that add turbulence
• Strength in design. A one piece upper pump body minimizes potential piping leaks and makes maintenance and service easy
• Horizontally split body allows for easy pump rebuilds without removing the pump body and plumbing resulting in less downtime
• Hale auto-lube system force feeds lubrication system eliminating the need for second packing or seal arrangement
• Standard G gearbox is capable of handling 16,000 lb. feet of torque (Optional K gearbox capable of handling 18,500 lb. feet of torque)
• Also available with optional SmartCAFS
