BETTER Casing Split Water Pump


Split Case pumps are designed to pump clean water or low viscosity clean liquids at moderate heads more economically, which is widely used for liquid transfer and circulation of clean or slightly polluted water.And the typical applications are Municipal water supply, Power plants, Industrial plants, Boiler feed and condensate systems, Irrigation and dewatering and marine service.


BT-S and BT-XS series of split case pumps are horizontal or vertical Single Stage Double Suction Pumps with closed impeller. All our pump body and casings are made by the advanced resin sand casting, and impellers are made by precision casting to meet the high performance under API610 &CE standard



Technical Advantage

A.      Less noise and vibration, suitable to a lifting speed working condition;

B.      Inverted running is available for the same rotor, the risk of water hammer is lower;

C.      Unique design for high temperature application up to 200 , intermediate support,thicker pump casing, cooling seals oil lubrication bearings;

D.     Vertical or horizontal with packing seal or merchanical seal can be designed according to the different working condition;

E.      Beautiful outline design.

Cost Advantage

A.  By advanced hydraulic model, the efficiency is 2%~3% higher;

B.  NPSH is 1-3 meters lower than the same type split case pumps, thus minimizing the foundation costs and extendling the using life;

C.  SKF, NSK bearing.

Maintenance Advantage

A.  Cartridge merchanical seals make the replacement much easier;

B.  Elastic prestressed assembly makes the rotor parts assemby and dismount much easier;

C.  Unnecessary to make adjustment when assembling.
