Single-Impeller Mine Water Axially Split Case Double Suction Centrifugal Pump

Product Description

The SCP pump is a high-performance, single-stage, axially split casing (middle open) pump with a double suction impeller, suitable for both horizontal and vertical installations. It excels in applications such as water supply, drainage, irrigation, power stations, construction, hydropower, fire-fighting, air-conditioning, and the building industry. It handles clean water, abrasive mediums like sand and oxide scale water, corrosive mediums like seawater, and high-temperature fluids up to 150°C.
With a capacity range of 52 to 35,000 m³/h and heads from 10 to 300 meters, the SCP pump operates under pressures up to 3.5 MPa. The axially split casing design allows for easy maintenance without disassembling the piping or motor. The dynamically balanced double-entry impeller ensures minimal axial thrust and efficient performance. The pump's durable construction includes an asbestos-free seal and long-life bearings, making it an ideal choice for demanding environments needing reliable and efficient fluid handling.
