About product

The CWS Series Marine Double Suction Horizontal Centrifugal Pump is a single-stage, mid-open centrifugal pump designed for marine applications. It is used for delivering fresh water and liquids with similar properties to water. With the option of a stainless steel overflow component or SEBF high-performance epoxy powder coating, it can also handle corrosive liquids. Commonly employed in float boatyards, this marine pump rotates in an anticlockwise direction when viewed from the motor. Its versatility and reliability make it an ideal choice for fluid transfer in marine environments.

Product Detail

Double Suction Horizontal Centrifugal Pump Construction

Double Suction Horizontal Centrifugal Pumps are constructed with several key components to ensure efficient fluid transfer and reliable operation. Here are the main components typically found in the construction of these marine pumps:

  • Casing: The casing is the outer shell of the pump and provides structural support. It houses the impeller and volute, and its design helps optimize fluid flow and minimize energy loss.
  • Impeller: The impeller is a rotating component that consists of curved blades or vanes. It is responsible for imparting energy to the fluid by increasing its velocity and directing it towards the volute.
  • Volute: The volute is a curved chamber surrounding the impeller. It helps convert the kinetic energy of the fluid into pressure energy by gradually expanding the flow area, resulting in increased pressure as the fluid exits the pump.
  • Shaft: The shaft connects the impeller to the motor or drive system. It transmits rotational power from the motor to the impeller, allowing it to rotate and propel the fluid.
  • Bearings: Bearings support the rotating shaft within the marine pump casing. They reduce friction and enable smooth operation by allowing the shaft to rotate freely.
  • Mechanical Seals: Mechanical seals are used to prevent leakage between the rotating shaft and the stationary casing. They ensure a tight seal to maintain pump efficiency and prevent fluid loss.

Double Suction Horizontal Centrifugal Pump Features

Marine Double Suction Horizontal Centrifugal Pumps offer specific features that make them well-suited for marine applications. Here are some key features associated with these pumps:

  • Double Suction Design: The double suction configuration allows the pump to draw in fluid from both sides of the impeller, resulting in balanced axial thrust and improved hydraulic efficiency. This design helps to minimize vibration and extend the pump’s lifespan.
  • Horizontal Orientation: The horizontal aspect of the pump means that the shaft and impeller are positioned horizontally, making it easier to integrate into marine systems and align with other components.
  • High Flow Capacity: Double suction pumps have larger impellers and casings compared to single suction marine pumps, enabling them to handle higher flow rates. This feature is advantageous in marine applications where large volumes of fluid need to be transferred efficiently.
  • Balanced Axial Thrust: The double suction design helps to balance the axial thrust forces on the impeller, reducing the load on the bearings and extending their service life. This feature contributes to improved pump reliability and reduced maintenance requirements.
