SOW Type Suction-Discharge Impeller Centrifugal Pump (Abbreviated: SOW Suction-Discharge Impeller Pump), a new type of single-stage, double-suction, open impeller centrifugal pump. It is primarily used for conveying clean water or liquids with physical and chemical properties similar to water at temperatures not exceeding 105°C. The SOW Suction-Discharge Impeller Centrifugal Pump is suitable for various applications such as waterworks, pumping stations, power stations, air conditioning circulating water, heating hot water circulation, industrial water supply systems, fire protection systems, ships, and oil refining industries (general liquids).

Operating Data

Export Diameter: DN=80-500mm

Flow Rate: 50 to 4,200 m³/h (rated point)

Flow Rate: H = 7.6～160m (rated point)

Allowable working pressure: 2.5 MPa

Allowable Test Pressure: 3.75 MPa

Medium: Pure water or other liquids with similar physical and chemical properties to pure water (solid particles ≤ 80mg/L)

Temperature: ≤105°C

Hydraulics: Optimized design of three hydraulic models ensures the pump boasts excellent hydraulic performance without the issue of axial force (theoretically), a common challenge for pump operation, especially for large pumps. The pump body, cover, and impeller are precision cast, with smooth flow surfaces enhancing the pump's anti-cavitation performance and efficiency.

Sealing: Filled seal or mechanical seal is adopted according to the conveying medium or customer requirements, without being restricted by direction changes. Sufficient space is provided for the replacement of packing material in the filled seal.

Operating Conditions of SOW Single-Stage Double-Suction Centrifugal Pumps:

Allowable working pressure is 2.5 MPa; that is, pump inlet pressure + pump head ≤ 2.5 MPa. The pump body and cover are made of gray cast iron (1.6 MPa), ductile iron (2.0 MPa), or cast steel (2.5 MPa) based on the maximum pressure the pump housing can withstand. Please specify the pump's pressure rating or material when placing an order.

Medium: Distilled water or other liquids with similar physical and chemical properties to distilled water at temperatures not exceeding 105°C (solid particles ≤ 80mg/L).

Bearings: Sealed rolling bearings with grease lubrication for easy maintenance and long service life. Equipped with a cup for maintaining a constant oil level, also available with light oil lubrication. High-quality imported bearings (SKF, NSK, NTN) chosen for smooth operation, low noise, and extended lifespan.
