Horizontal Split Casing Pump

The split casing pump is a new type of single stage double suction centrifugal split pumps with high performance, which are widely used in water delivery in the water plant, circulation water system of air-conditioner, heated water supply, construction, drainage pumping station, power station, industrial water supply system, ship industry, mine, etc.

XS type split casing pump is the new generation of high performance single stage double suction centrifugal pump, mainly used for water plant, air conditioning, water recycling, heating systems, and high-rise building water supply, irrigation and drainage pumping stations, power plants, industrial water supply system , Fire systems, shipbuilding industry, and other places of fluid transmission is the full replacement of SH, S, SA, SLA, SAP type double suction pump. 

Model Description 
Example: XS250-480A-L-R (M.F)-J

Technical Advantage:
1.     Short bearing support, enables the split casing pump work stably with less noise and vibration.
2.     The pipelines arrangement of the split casing pump looks simple and beautiful due to inlet and outlet at a same center line.
3.     The same rotor of the split casing pump can be operated at reverse direction to avoid damage to the pumps by water hammer.
4.     Unique design of middle support, thicker pump casing and using cooling seals, oil lubrication bearing, makes the split casing pump suitable for working at 200 temperature.
5.     The split casing pump can be vertically or horizontally mounted, and the shaft seal can be gland packing seal or mech. Seal.

Cost Advantage:
1.     The efficiency of XS pumps are 2%~3% higher than the same type pumps due to adopting advanced hydraulic model and thus minimum the operating costs.
2.     The NPSH of the split casing pump is 1-3 meters higher than the same type split pumps, thus minimize the foundation costs and extending the using life.
3.     The split casing pump is suitable for any site working condition due to using SKF NSK bearing and other parts chosen by the customers and thus minimize the maintenance costs.

Maintenance Advantages:
1.     It is very easy and simple to replace the mechanical seal due to using cartridge type mechanical seal.
2.     It is rapid easy to assembly and disassembly the rotor parts due to using elastic prestress assembling.
3.     It is unnecessary to make adjustment when assembling.

Common failures of self-priming pumps

During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.

Classification and difference of submersible pumps

The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
