Double Suction Split Case Pump

Product Introduction The Series is a high-capacity, high-efficiency centrifugal pump, defined by its robust double suction and axially split case design. This pump is the workhorse for heavy-duty applications that require moving massive volumes of water, such as large-scale agricultural irrigation, municipal water supply, and major industrial water systems. Its engineering focus on hydraulic balance and ease of maintenance makes it the premier choice for critical, continuous-duty service where reliability and low operational costs are essential.


Design Philosophy & Construction The pump is engineered for superior performance and simple serviceability in high-flow applications.

  • Double Suction Impeller: The key to the pump’s performance is its impeller, which is designed to draw water in from both sides simultaneously. This dual-inlet design perfectly balances the axial hydraulic forces on the shaft. By neutralizing this thrust, the load on the bearings is dramatically reduced, leading to significantly longer bearing life, less vibration, and higher overall reliability compared to end-suction pumps.
  • Axially Split Casing: The pump casing is split horizontally along the centerline of the shaft into a top and bottom half. The main suction and discharge piping are connected to the bottom half of the casing. This brilliant design allows maintenance crews to simply unbolt and lift off the top half of the casing to gain complete access to the entire rotating assembly (impeller, shaft, bearings, and seals) without ever having to disturb the motor or the main pipelines.

Key Features & Benefits

  • High Hydraulic Efficiency: The double suction design is inherently more efficient at high flow rates, which translates to significant energy savings over the pump’s lifetime.
  • Exceptional Reliability: The balanced axial thrust minimizes stress on the bearings, leading to a much longer service life and greater reliability for continuous 24/7 operation.
  • Unmatched Ease of Maintenance: The split case design is the easiest to service of any pump type. It allows for quick inspections and repairs, drastically reducing maintenance downtime.
  • Very High Flow Rate Capability: This design is specifically intended for moving large volumes of water, making it ideal for bulk transfer applications.
  • Stable and Low-Vibration: The robust construction and hydraulically balanced design result in exceptionally smooth and quiet operation, even in large sizes.

Common Applications The pump is the standard choice for high-volume, heavy-duty water transfer:

  • Agricultural Irrigation: The primary pump for drawing massive amounts of water from rivers, lakes, and reservoirs for large-scale farming.
  • Municipal Water Supply: Used as raw water intake pumps at treatment plants and as high-volume distribution pumps for city water networks.
  • Industrial Water Systems: The main circulation pump for cooling water in power plants, steel mills, and large manufacturing facilities.
  • Flood Control: Used in large pumping stations to manage storm water and for land drainage.
  • Desalination Plants: Often used as the main seawater intake pumps.
