    In this blog, we will take a detailed look at what split case pumps are, their design and working principle, applications, and the key benefits that make them an essential choice for demanding operations.

    What Are Split Case Pumps?

    Split Case Pumps are a type of centrifugal pump in which the pump casing is split into two sections—either horizontally or vertically. This split design allows easy access to internal components like the impeller, shaft, and bearings without disturbing the piping system.

    These pumps are specifically designed to handle large volumes of liquid at relatively low to medium heads, making them ideal for applications requiring consistent and uninterrupted flow.

    Design of Split Case Pumps

    The unique design of split case pumps sets them apart from other centrifugal pump types.

    1. Split Casing Construction

    The casing is divided into two halves:

    • Horizontally split case pumps – The casing is split along the horizontal centerline.
    • Vertically split case pumps – The casing is split vertically, often used where floor space is limited.

    This design simplifies inspection, maintenance, and servicing.

    2. Double Suction Impeller

    Most split case pumps use a double suction impeller, where liquid enters from both sides of the impeller. This design:

    • Balances axial thrust
    • Reduces bearing load
    • Improves hydraulic efficiency

    3. Shaft and Bearings

    The shaft is supported by heavy-duty bearings designed for continuous operation. Balanced hydraulic forces help extend bearing life and reduce vibration.

    4. Mechanical Seals or Gland Packing

    Split case pumps can be equipped with mechanical seals or packing seals, depending on the application and operating conditions.

    Working Principle of Split Case Pumps

    The working principle of Split Case Pumps is based on centrifugal force:

    1. Liquid enters the pump from both sides of the impeller.
    2. The rotating impeller imparts kinetic energy to the liquid.
    3. Centrifugal force pushes the liquid outward toward the casing.
    4. The casing converts velocity energy into pressure energy.
    5. The liquid exits through the discharge nozzle at a steady and controlled flow rate.

    The double suction design ensures smoother operation with reduced hydraulic imbalance.
