Self-priming Pump

Self priming pump is a centrifugal pump with built-in self-priming function, which does not require pre pumping. It forms a vacuum suction medium through the pump body structure, making it easy to start and stop, and suitable for working conditions without self-priming ability.Widely used in industries such as water supply and drainage, municipal engineering, chemical engineering, agricultural irrigation, etc., for conveying clean water, sewage, and light corrosive liquids, suitable for conveying scenarios with low liquid level, high suction, and frequent start stop.

Common Types

  • Self priming centrifugal pump: with high flow rate, suitable for conventional transportation of clean water and light media
  • Self suction sewage pump: anti clogging flow channel, suitable for conveying impurities and sewage
  • Stainless steel self-priming pump: corrosion-resistant, suitable for light corrosive media such as acid and alkali
  • Pneumatic self-priming pump: explosion-proof, suitable for transporting flammable and explosive media in chemical industry

Structural Advantages & Corresponding Benefits

  1. Gas liquid separation self-priming chamber structure

  • Special point: The pump body integrates a gas-liquid separation chamber, and the impeller rotates to form a high vacuum, automatically exhausting air and absorbing liquid
  • Result:No need for pumping, fast self-priming speed, high suction range, suitable for conveying low liquid level media

  1. Non clogging impeller flow channel structure

  • Special point: The impeller adopts a large channel design, with smooth flow channels and no dead corners, and is wear-resistant and impact resistant
  • Result:  It can transport media containing a small amount of impurities, is not easily blocked, runs stably, and has low maintenance frequency
