Basic Design Differences, The first and most obvious difference is the orientation of the shaft. A horizontal centrifugal pump will have its shaft placed horizontally, typically between the bearings or overhung. Meanwhile, a vertical centrifugal pump has a shaft that is oriented vertically. The design of the shaft is radial split and overhang.

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 

Inspection and Repair– In general, the horizontal pump is far more accessible for inspection, maintenance and repair than the vertical turbine pump. There are undoubtedly exceptions to this, plus the fact that ease of maintenance of various types of horizontals will vary considerably.

In my opinion the advantages of the vertical inline pump over Split case vertically mounted pumps are. 1) Direct installation in the pipeline,so minimal space required. 2) No alignment of pump and driver. 3) No baseplate, coupling or guard. Disadvantages:limited to weight of the motor drive.

Vertical Split Case Pumps Require Half the Floor Space of a Horizontal Split Case Pump Inline Piping Arrangement Allows for Piping in Any Direction Elevated Motor Protects Against Potential Flooding if the Pump Station is in a Low Area Applications Include: Cooling, Heating and Air Conditioning Service Boiler Feed Service Condensate Service

Vertical turbine and horizontal split case centrifugal pumps are the most common types of pumps utilized in water applications.

May 21,  · Split-case also may have multiple impellers for multi-stage operation. Multiple impellers provide increased available head within a single pump. Split-case pumps are available as horizontal or vertical split-case. For horizontal split-case pumps, the impeller casing is split in the horizontal plane.

Jan 11,  · On a vertical inline pump, you don't need to use an inertia base because the deflection from the weight of the impeller runs with the shaft not perpendicular to it like the

The split case pump is also more robust and designed for continuous use as additional bearings are installed in the pump head, these take a large deal of strain away from the motor during operation. The split casing design allows the easy disassembly of the rotor group without distorting the pump alignment or the suction and discharge pipework, this in turn allows time saving while the pump is serviced/maintained.

Due to the large flanges required for the split casing sealing joint, larger impeller, and overall large size, horizontal split case pumps 

more expensive than a horizontal process pump made with the same high alloy and designed for the same service. Inspection and Repair - In general, the horizontal pump is far more accessible for inspection, maintenance and repair than the vertical turbine pump. There are undoubtedly exceptions to this, plus the fact that ease of maintenance of
