Split Case Pumps are types of centrifugal pumps that have a single or double suction impeller supported between bearings. The Split Case Pump casing is split horizontally or vertically depending on the type of pump, for maintenance. Suction and discharge flanges are opposed to each other. Usually designed to mount horizontally but may also be designed for vertical installation, hence Horizontal Split Case Pump or Vertical Split Case Pump.
Split Case Pumps have a double suction impeller which gives better Net Positive Suction Head (NPSH) and lower axial thrust. Casing is normally double volute, to reduce radial bearing loads. Pump has two seals, both sealing suction pressure.
Split Case Pumps usually are used in higher flow rate applications than end suction pumps. Used for cooling water, plant make-up water, potable water distribution, fire pumps, pipelines, and other main process flows.
Split Case Pumps pump water and relatively thin liquids (will not pump thicker oils), normally not used for liquids containing solids. Available in alloys for corrosive services.
Split Case Pumps permits much higher flow rates than end suction pumps. The double suction impeller has no axial thrust loads, and is less likely to cavitate.
