Features and Applications
XS type mariner pump is a new generation of high performance single- stage double-suction centrifugal split pumps. They are suitable for transporting water or water-like liquids at temperature -20 deg c~105deg c (XS type), -60 deg c~200 deg c (XS-R type). Type XS pumps are widely used in delivering liquids of the water plant, airconditioner circulation water, heating pipe network system, building water supply, irrigation and drainage of pump stations, power plants, industrial water supply system, fire protection, ships industry and mine. It is a new substitute of SH, S, SA, SLA and SAP pumps.

Description of Pump Type
For example:
XS 250-450 A- L-R(M. F)- J
XS: Advanced type split centrifugal pump
250: Pump outlet diameter(mm)
450: Impeller diamete(rmm)
A: Changed outer diameter of impeller (the max diameter without mark)
L: Vertical mount
F: Anti-corrosive
M: Anti-abrasive
R: Heating water
J: Mechanical seal

Structure Feature
1. Type XS marine 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 marine pump looks simple and beautiful due to inlet and outlet at the same line.
3. The same rotor of type XS marine pumps can be operated in reverse direction to avoid damage to the pumps by water hammer.
4. Unique design of high temperatare form: Using middle support, thickening the pump casing, using cooling seals and oil lubrication bearing, make XS pump suitable for working at 200 degree Celsius, especially for suppling heating net system.
5. Type XS marine pump can be vertically or horizontally mounted acoording to different working condition, with mechanical seals or packing seals.
6. With industrial design, the outline of XS is clear and beatitiful in line with modern aesthetics.
7. The efficiency of XS marine 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 NPSH of type XS marine pumps are 1-3 meters lower than the same type split 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.
