Single Stage Centrifugal End Suction Pump

Description of the Single Stage Centrifugal End Suction Pump

The NSWA single-stage horizontal end-suction water  pump is an innovative and newly developed pump by our company based on the horizontal water circulation pump. It fully considers the special requirements of low water and energy consumption during the pump's operation, draws on advanced structural experience from both domestic and international sources, and adopts a split shaft and special clamping structure. It features a simple structure, high concentricity, low vibration, reliable operation, and easy maintenance.

 The NSWA  horizontal water circulation pump is a new generation of single-stage end-suction centrifugal pump, similar to the Grundfos NBG series end suction pump. It is widely used in fields such as air conditioning, heating, domestic water supply, water treatment, cooling and refrigeration systems, liquid circulation and supply, boosting, and irrigation, to transport non-corrosive cold and hot water. The pump operates at speeds of 2960 r/min and 1480 r/min, with a flow range of 4 to 1600m³/h and a head of less than 85m.

 The NSWA end suction water circulation pump is suitable for media temperatures ranging from -1°C to 80°C, and up to 120°C with high-temperature mechanical seals, O-ring seals, and flushing schemes. The maximum ambient temperature for the pump is +40°C.

Application of Single Stage Centrifugal End Suction Pump:

The main function of the Single Stage Centrifugal End Suction Pump is to transport clean water and other liquids whose 

physical and chemical properties are similar to clean water. HVAC refrigeration cycle, bathroom and other 

cold and warm water cycle pressurization and equipment matching, operating temperature T<80°C
