Our support program includes technical consultation, installation guidance, and maintenance services to ensure the pump performs optimally in all applications.
Technical Specifications
Pump Outlet Diameter: DN 80–900 mm
Supports a wide range of outlet sizes from medium to ultra-large flow systems.
This flexibility allows the pump to be used in both municipal infrastructure and large-scale industrial water transfer projects, ensuring strong adaptability across different engineering requirements.
Capacity:: 22–16236 m³/h
Handles extremely wide flow capacity ranges, from small operational systems to high-volume water transportation.
This ensures stable performance under varying load conditions and makes the pump suitable for complex and large-scale water supply or drainage applications.
Head: H = 7–300 m
Provides a broad head range suitable for low-lift to high-pressure pumping conditions.
This allows the pump to maintain efficient operation in different hydraulic environments, including long-distance water delivery and high-elevation systems.
Temperature: T = -20°C to 200°C
Designed to operate reliably under both low-temperature and high-temperature fluid conditions.
This makes it suitable for diverse industrial environments such as heating systems, cooling circulation, and process water transport.
Solid Parameter: < 80 mg/L
Capable of handling fluids with low solid content without affecting performance stability.
This ensures smooth operation, reduces wear on internal components, and extends the overall service life of the pump.
Permissible Pressure: < 5MPa
Built to withstand high-pressure working conditions safely within industrial standards.
This enhances operational safety and reliability, making it suitable for demanding applications such as power plants and large municipal systems.
Model Features
1.Type XS split case pumps work stably with less noise and vibration, may be properly work at raising speed due to short spacing between both side supports, thus they can be widely used.
2.The pipelines arrangement of type XS split case pump looks simple and beautiful due to inlet and outlet at the same line.
3.The same rotor of type XS split case pumps can be operated in reverse direction to avoid damage to the pumps by water hammer.
4.Unique design of high temperature form: using middle support, thickening the pump casing, using cooling seals and oil lubrication bearing, make XS split case pump suitable for working at 200℃, especially for supplying heating net system.
5.Type XS split case pump can be vertically or horizontally mounted according to different working condition, with mechanical seals or packing seals.
6.With industrial design, the outline of XS split case pump is clear and beautiful in line with modern aesthetics.
7.The efficiency of XS split case pumps are 2% - 3% higher than the same type pumps due to adopting advanced hydraulic model and thus reduce the operating costs significantly.
8.The NPSHr of type XS split case pumps are 1 - 3 meters lower than the same split type pumps which reduced the foundation costs and extend the using life.
9.Choosing import brand bearing, and other parts material chosen by customer, make the pump suitable for any operation condition and reduce the maintenance cost significantly.
10.It is not necessary to adjust mechanical seals, so it is very easy and simple to replace them.
11.It is rapid and simple to assemble and dismount the rotor parts due to using elastic prestress assembling.
12.It is unnecessary to make adjustment to any clearance when assembling.
