Horizontal Split Case Pump Sales and Service

At London Pump Supply Ltd., we supply both vertical and horizontal split case pumps. We also provide a range of repair services for split casing pumps, including options for on-site or in-shop repair at our London, Ontario facility, which services our clients all across Southwestern, Ontario. Split case pumps are a type of centrifugal pump in which the pump case is split into two different chambers. The impeller is mounted onto a shaft which is supported by bearings on both sides.

Horizontal split case pumps and how they work

A horizontal split case pump means the casing is on a horizontal plane when compared to the impeller (rather than along a vertical plane.) This is advantageous for large pumps as the casing structure provides a more economical system because the impeller can have bearings on either side for support.

Most split case pump casings are structured for horizontal installations, but they can also be configured to be mounted vertically which is the primary distinction between horizontal split case pumps and vertical split case pumps.

Applications for horizontal split case pumps

Usually this type of pump is used for higher flow rate applications such fire pumps, potable water distribution, plant make-up water, cooling water and other main process flows. Horizontal split case pumps are used for water and sometimes thinner liquids. Pumps made from alloys are available to avoid corrosion.

Features of horizontal split case pumps

Both the suction and discharge connections are opposed to each other and are located on the casing’s lower portion. The impeller is mounted and supported on both sides.

Advantages of horizontal split case pumps

In situations where the flow rate is significant, horizontal split case pumps are used. Because the impeller has double suction, it carries no axial thrust loads, making it much less prone to cavitation.
