0.4MPa Double Suction Split Case Pump

42.5m head, 360m3/h flow capacity, Single Stage Double Suction Split Case Water Pump 250S39

 

 

A horizontal split case pump is a unique type of centrifugal pump whose casing is divided into two distinct chambers, which is different from inline or end suction pumps that are assembled with the suction nozzle, discharge nozzle, and casing in one chamber.

 

 

Horizontal split case centrifugal pumps are designed with the suction and discharge nozzles in the bottom half of the casing, side by side, while the impeller shaft is positioned between two bearings, one on each side.

This rugged but simple design is particularly suitable for higher flow applications as it reduces thrust loads and allows for operation over a broad range of capacities. With proper application, HSC pumps offer minimal power consumption, low maintenance costs, and extended service life.

 

Other design features of HSC pumps include:
A double suction impeller that offers lower axial thrust and superior Net Positive Suction Head (NPSH)
Double volute casing to minimize radial bearing loads
Dual pump seals to seal suction pressure

Advantages of HSC pumps:

HSC pumps have a smaller footprint compared with a frame-mounted pump of the same rating (in most cases).
The top half of the casing is easy to remove for inspection of the rotor, and you do not need to disturb the driver or the piping to accomplish this inspection.
They typically have higher efficiencies than frame-mounted pumps of the same size.
Because of the dual-eye (dual-suction) impeller design, there are lower net positive suction head required (NPSHR) factors and lower axial thrust.
This design lends itself to a short shaft with the result of low deflection. This article limits the discussion to one- or two-stage HSC pumps with the impeller situated between the bearings; this design is also known as “between bearings” (API 610- BB-1).
Typically these pumps offer dual volute construction, which significantly reduces the radial thrust component.
