CTM Mag Drive Centrifugal Pump Installation

Article sections

    Tapflo’s CTM Pump range is a Magnetically Driven Centrifugal Pump. This pump’s design uses magnets to couple the motor to the pump instead of by a mechanical shaft.

    Installation Example

    Mag Drive Centrifugal Pump Installation

    NumberPermissibleDetail
    1YESGate Valve – may also be fitted closer to the pump in case of long pipework
    2N/AWith a positive head tilt the pipework towards the direction of the pump inlet
    3YESIn-Line Strainer – required if there are particles present, larger than 6mm
    4NOAir Pockets – the circuit needs to be as short and as straight as possible
    5YESPipe Connectors
    6N/ASuction line needs to be as short and direct as possible, ideally the same size as the pump inlet or 1 size larger
    7YESGate Valve – useful for regulating the performance of the pump
    8N/ABends in the pipework need to be ideally placed after any valves and instrumentation and ideally placed five times the ø of the pipework away. I.e. if the pipework is 25mm then any bends would ideally need to be placed 125mm away from the pump and any valves or instrumentation.
    9YESAttachment for Pressure Gauge or Pressure Relief Valve. It is best practice to install a Pressure Gauge on the discharge of the pump to evaluate where it is working on its curve. A Pressure Relief Valve is required when there is a possibility for “Dead Head” operation or when using a nozzle for example.
    10NOElbow Joints & other bends on the pump suction or discharge ports
    12YESCheck  Valve/Non-return Valve, essential when operating a suction life application.
    13N/ASuction Strainer, essential when there is the potential for solids in suspension larger than the capability of the pump.
    14N/ASuction Head – ensure that the difference in height between the pump inlet and the surface of the fluid (NPSHa) is sufficient for the safe operation of the pump to avoid cavitation. This can be provided upon request.
    15N/ASuction Lift – when operating the pump in a suction lift application, ensure that the suction pipework is as short as possible and contains as few bends as possible. The distance between the pump inlet and the surface of the fluids needs to be no more than the capability of the pump in questions.
    16N/ASurface of the fluid and Immersion Depth – the distance between the surface of the fluid and the bottom of the suction pipe. Ensure that this is sufficient to avoid the loss of fluid in the suction pipe when the fluid source is depleted.
    17YESExpansion Joint – indispensable with long pipework and/or hot liquids. Anti-Vibration Facility – considered best practice when using the pump on a fixed & rigid pipework.
    18YESOvercome obstacles on both the suction and discharge by lowering the pipework where possible. Essential on the suction side, ideal on the discharge side. This reduces the work the pump has to overcome as well as eliminating the possibility of air pockets.
    19YESFix the pump into the installation by the fixing holes provided, the supports and/or base must be level.
