Product Description
Product Overview
TSWA horizontal low-speed multistage centrifugal pumps are designed for delivering clean water or liquids with physical and chemical properties similar to clean water and without solid particles. They are mainly used for high-pressure water supply, high-rise building water supply, and industrial water transfer and drainage. The pump flow range is 10–155 m³/h, the head range is 15–300 m, the motor power ranges from 2.2–200 kW, and the inlet/outlet sizes range from 50–150 mm. The allowable medium temperature of TSWA pumps does not exceed 80°C.
Series Type Designation

Product Features
- TSWA horizontal low-speed multistage centrifugal pumps feature a compact structure, small footprint, elegant appearance, and reduced construction cost.
- The rotor assembly is supported by rolling bearings at both ends, ensuring smooth and stable pump operation.
- The pump inlet is horizontally arranged and the outlet is vertically upward, simplifying pipeline installation.
- The motor is horizontally mounted for easy maintenance.
Applications
These pumps are mainly used for domestic water supply in high-rise buildings, fire-fighting constant-pressure systems, automatic sprinkler systems, and water curtain systems. They are also suitable for industrial and mining water transfer, long-distance water delivery, equipment matching, and various process water applications.
Operating Conditions
- Suitable for clean water or liquids with similar physical and chemical properties; solid impurities should not exceed 0.1% by volume, particle size ≤ 2 mm.
- Medium temperature: –15°C to 80°C.
- Working pressure: system pressure ≤ 3.0 MPa (system pressure = inlet pressure + pump operating pressure).
- Ambient temperature should be below 40°C; relative humidity below 95%.
- As the pump’s main components are cast iron, the medium should be non-corrosive.
Note: If the medium contains fine particles or is strongly corrosive, please specify when ordering so a more reliable configuration can be provided.
