- Pump Type Single cutwater end suction centrifugal pump mounted on a gearbox.
- Pump Body and Head Fine grain alloy cast iron standard with bronze alloy available upon request. Ruggedly constructed and accurately machined. Hydrostatically tested to 500 psi to
ensure safe high pressure operation. Carefully engineered smooth waterways for maximum pumping efficiency.
- Impeller Fully enclosed, high strength bronze impeller fully machined and hand balanced. Smooth internal waterways and mixed flow impeller vanes for highest efficiency and lift capacity. Balanced for reduced bearing loads.
- Clearance Rings Two renewable bronze clearance rings, one front, and one rear of impeller for higher efficiency.
- Pump Shaft Heat treated stainless steel for corrosion resistance and high strength. Pump shaft supported by high capacity roller bearings for maximum life and minimum wear.
- Suction 8 x 13 ASA flange connection provided as standard.
- Discharge 6 x 9 ASA flange connection provided as standard.
- Pump Seal Balanced mechanical seal with special design silicon carbide and carbon pump shaft seal seats for maximum resistance to thermal shock, sand and mud. Self lubricating and self adjusting mechanical seal for long life.
- Gearbox Shall be designed and tested at the pump manufacturer’s factory. (No exceptions). Pump Gearbox shall be of sufficient size to withstand up to 18,500 Lb. FT of drive torque of the engine in both road and pump operating conditions. The gearbox shall be designed of ample capacity for lubrication reserve and to maintain the proper operating temperature. Gearbox shall be close coupled to the pump. (No exceptions)
- Gearbox Drive Shafts Shall be of heat treated chrome nickel steel and at least 2-3/4 inches in diameter, on both the input and output drive shafts. They shall withstand the full torque of the engine in both road and pump operating conditions.
- All Drive and Pump Gears Shall be of highest quality electric furnace chrome nickel steel. Bores shall be ground to size and teeth integrated crown-shaved and hardened, to give an extremely accurate gear for long life, smooth, quiet running and higher load carrying capability. An accurately cut high contact ratio helical design shall be provided. (No exceptions).
- Pump Ratio Shall be selected by the apparatus manufacturer to give maximum performance with the engine and transmission selected.
