Product Description

Brief introduction:

The XS-type pump is a next-generation, high-efficiency single-stage double-suction centrifugal split-case pump, engineered for demanding fluid transfer applications across multiple industries.

Primary Applications:

• Water Treatment Plants - Reliable liquid transfer for purification and distribution

• HVAC Systems - Efficient circulation of chilled and heated water

• District Heating Networks - High-capacity hot water delivery

• Municipal Water Supply - Building and urban water distribution

• Pump Stations - Irrigation, drainage, and flood control

• Power Plants - Cooling water and process fluid handling

• Industrial Water Systems - Robust performance for manufacturing and processing

• Fire Protection Systems - Dependable water supply for emergency systems

• Marine & Shipbuilding - Corrosion-resistant solutions for seawater and onboard systems

• Mining Operations - Durable pumping for dewatering and slurry transport

Key Advantages:

 High Efficiency - Optimized hydraulic design reduces energy consumption
 Dual Suction Design - Balanced axial thrust for smoother operation
 Split-Case Construction - Easy maintenance and inspection
 Wide Flow Range - Adaptable to varying system demands

Parameters:
 

Flow rate:	Q=22~16236 m3/h
Total head:	H=7~300 m
Speed:	n=980rpm/2950rpm
Solid parameter:	≤80 mg/L
Temperature:	T=-20~200 ºC
Pump diameter:	80~900 mm

Features:

1. Using excellent hydraulic model, the efficiency of the pump is 2-3% higher than that of the same type, and the operating cost of the pump is reduced.  
2. Unique high temperature design, the pump adopts intermediate support, thickened pump body, sealed cooling, bearing thin oil lubrication, so that the pump can be applied to the high 200ºC operating conditions, especially suitable for heating pipe network requirements  .
3. The pump body part can be installed vertically or horizontally according to different working conditions, and the seal can be mechanical seal or packing seal.  
4. The NPSHr is reduced by 1-3 m.
5. It is unnecessary to adjust mechanical seals,so it is very easy and simple to replace them.
6. It is rapid and simple to assemble and dismount the rotor parts due to using elastic prestress assembling.

Structure:

1. The distance between the two ends of the pump is short, the pump runs stably, the vibration noise is small, and the speed can be increased properly, so that the pump can adapt to a wider range.  
2. The inlet and outlet are in the same straight line, so that the pipeline layout is simple, convenient and beautiful.  
3. The same rotor can run in reverse, reducing the risk of water hammer damage to the pump.
4. It is unnecessary to make adjustment to any clearance when assembling.
