Planning Installation – Suction Lift

Suction Lift

Suction lift varies according to pump characteristic, type and temperature of the liquid handled and piping conditions, when preparing a plan for instalation, the following should be taken into consideration

  • Normal temperature, fresh water: Height from suction-water surface to pump center-within 6m
  • High water temperature: Suction lift decreases when temperature increases


  • Long suction pipe: A long suction pipe reduces suction lift due to the increase in pipeline resistance.
  • Handing of vapor liquids Certain chemical and coal oils are highly volatile and, when handled, the pump may require a flooded suction system. It is recommended selectio of a pump and the equipment plan be based on characteristics of the liquid as obtained from its manufacturer
