Model Meaning

product overview

The zsoW series single-stage double suction open volute centrifugal pump is produced by our company based on market demand and technology introduction. The pump uses prototype impellers and modified impellers and their cutting, with a full and wide profile and high efficiency. Within the performance range of the profile, it can provide users with the required flow and head working point water pump.

The zSoW pump adopts excellent hydraulic models that can self balance axial and radial forces at home and abroad, with stable performance, high efficiency, compact structure, low vibration, high pump pressure resistance, and easy installation and maintenance.

Main purpose

The zsow series products are widely used in water plants, irrigation, drainage pump stations, power stations, air conditioning circulating water, industrial water supply systems, fire protection systems, shipbuilding industry, and are also suitable for general use in the oil refining industry.

hydraulic performance

By utilizing advanced computer-aided software procurement and modern design methods (i.e. optimization design and reliability design methods) internationally, the hydraulic and structural design of the ZSOW double suction pump is carried out, resulting in high efficiency and significant anti cavitation performance. Compared with similar domestic products, this series of products has a 2-4 percentage point higher efficiency and significantly improved cavitation performance, which will save users a lot of money.

Structural characteristics

1. Compact structure: Beautiful appearance, good stability, and easy installation.

2. Operation balance: The optimized design of the double suction impeller reduces axial force to a low limit and has excellent hydraulic performance. The blade profile is precision cast, and the pump's bright inner surface and impeller surface are extremely smooth, with significant anti cavitation performance and high efficiency.

3. The pump housing adopts a double volute structure, which greatly reduces radial force, reduces shaft bearing force, and extends the service life of bearings.

4. Bearings: Choose domestically produced or world-renowned brand bearings to ensure balanced operation, low noise, and long service life.

5. Shaft seal: Choose mechanical seal or packing seal. Can ensure 8000 hours of operation without leakage

working conditions

The working pressure of the zsoW snail shell double suction pump system is 2.5MPa, which means that the pump inlet pressure+pump head is less than 2.5MPa. The static pressure test pressure of the pump is less than 3.75MPa. According to the pressure borne by the pump body, the materials of the pump body and pump cover are gray cast iron (1.6MPa), ductile iron (2.0MPa), and cast steel (2.5MPa). Please indicate the pressure or material of the pump when ordering.

This series of pumps delivers clean water with a temperature T<105 ℃ or other liquids with physical and chemical properties similar to clean water.
