A detailed review on Self Priming Pumps

In many liquid pump applications, the pump must be above liquid level to allow air to enter the line. This can lead to problems such as overheating and line failure. Pump. To avoid this problem, a self-priming pump is used to deflate the air before transferring the liquid. Gainesville Industrial Electric (GIE) offers a wide range of automated pumps to meet the requirements of a variety of applications.

Self-Priming pump :

                   Pumps that are partially or completely above the fluid level allow air into the suction line, which must be evacuated or displaced before the pump can move the liquid. Self-priming pumps are capable of removing air at startup before beginning their normal pumping functions.

 Working Principale of Self-Priming Pumps:

To prevent air and water mixing, a self-priming pump creates a small vacuum to remove the water as the air contracts. This is done by mixing air and water during cooking to raise the air and move the water up and down. Gravity then draws water-free air into the turbine where it mixes with the rest of the air in the intake line. This process is repeated until all air has been removed and negative pressure is created in the suction line. In this case, atmospheric pressure pushes water into the suction line and starts the pump towards the impeller.

Application of Self-Priming Pumps:

Automatic pumps are used in many industrial and commercial plants such as steel mills, power plants, wastewater treatment plants, cellars, and breweries. Some common applications are,

  • Pumping water, fuels, clear or gray water, raw sewage, industrial wastewater, and more
  • Liquid transfer systems
  • Irrigation
  • Basement floodwater pumps
  • Bailing out boats
  • Increasing water pressure
  • Sewage treatment
