Pumps and Lift Stations

Lift stations or pump stations are used to move liquids from a lower to a higher elevation. By moving the fluid (such as water or sewage) to a higher elevation, drainage or transportation systems that use gravity can be utilized, which may be more cost efficient.

Lift stations utilize different types of pumps and machinery depending on the type of system and its purpose. Some lift stations are designed for low viscosity fluids while others are designed for high viscosity fluids. Lift stations can be customized for any purpose that requires moving liquids in varying elevations, and there are several different features and specifications to consider with each type of station.

Some of the specifications of lift stations

Some of the specification of lift stations include the reservoir size, the number of pumps, maximum flow rate and pressure, head and discharge size. Each of these specifications is described below:

  • Head – the energy supplied to the fluid by the pump (per unit weight). Head is expressed in feet of head or as a column height of a liquid.
  • Reservoir size – the maximum capacity of the storage tank or reservoir, this is usually expressed in gallons.
  • Maximum pressure – the maximum pressure that the lift station system is created to handle, expressed in pounds per square inch.
  • Maximum flow rate – this is the maximum rate of liquid flow through the system, expressed in gallons per minute.
  • Number of pumps – the number of pumps in a lift station determine the head and the capacity of the station, and also determines the amount of power that is needed for the system.
  • Discharge size – this is the diameter of the outlet in the station.

Components of a lift station

Depending on the type of lift station, there can be several different components including the following:

  • Pressure sensors – these detect fluid pressure throughout the system.
  • Housing – this is the casing or structure that houses the lift station, pumps and the other components.
  • Pumps – these provide the power for the lift station, and they may be external or submersible depending on the type of system and the need.
  • Control systems – these are used in combination with pressure sensors to control the operation of the station.
  • Generators – these are used to power the lift station if external power is lost.
  • Level sensing probes – determine the fluid level in the lift station.
