  • The Valves of a Centrifugal Pump IDCOnline

    The Valves of a Centrifugal Pump The suction and discharge piping of a centrifugal pump, will generally have the following valve arrangements : 1. Suction Valve: Allows liquid to enter the pump. 2. Discharge Valve: Allows liquid to flow from the pump to other parts of the system. 3. Check or NonReturn Valve: In the discharge line Prevents

  • Why Discharge Valve Closed During Starting of Centrifugal

    >If you start the pump discharge valve closed, it means no discharge head minimum resistance to the pump and minimum current drawn. Even though current taken during startup is more than normal, by closing discharge valve you can avoid extra load on the pump >If you have a check valve, then the discharge valve can be opened.

  • Check valve KSB

    A check valve, or nonreturn valve, prevents reverse flow by ensuring that fluid can only flow in one direction along a pipeline. It can be installed, for example, in the discharge lines of pumps operating in parallel (see Parallel operation) (where at least one pump is not running) to prevent both reverse flow of fluid handled and the

  • Centrifugal pump system tips, do's and dont's

    In residential systems, to ensure that the pump stays full of the liquid use a check valve (also called a foot valve) at the water source end of the suction line. Certain types of centrifugal pumps do not require a check valve as they can generate suction at the pump inlet to lift the fluid into the pump.

  • CHECK VALVES FOR PUMP DISCHARGE SOCLA

    CHECK VALVES FOR PUMP DISCHARGE Two of the most common problems with check valves are reverse flow and water hammer. In both situations, a fastclosing valve is required. Reverse flow can be expensive, especially if it occurs at the discharge of a pump and the pump spins backwards.
