What is a Submersible Pump Shroud or Sleeve?

PVC pump shrouds are installed over the body of the pump and motor so that the water flow past the motor is sufficient to achieve adequate cooling of the motor. Easy to fit and definitely required if you are installing the submersible pump in a well or bore with a diameter of 200mm or greater. You can buy ready to use shrouds or sleeves of standard pump sizes, alternatively a shroud or sleeve can be made from PVC Pipe. A shroud is always required in an open body of water eg. a dam or river, or a cascading bore. A pump shroud should also be used if the pump is to be installed below water inlet level. This protects the pump from damage from falling sand and ensures correct velocity of water over motor for cooling purposes. Fitting a shroud over the pump intake and motor casing will ensure that cool underground water flows upwards over the motor casing on its way to the intake, ensuring that the motor stays cool. The shroud is a tube open only at its base enclosing the submersible pump. ... more
