Quantity
    A leak-free plastic water pump designed for corrosive, toxic, or high-purity chemical media. Featuring a plastic pump body immersed in liquid and an externally mounted motor, it solves traditional sealing issues while ensuring safety for flammable/explosive environments. Ideal for chemical, pharmaceutical, and high-purity industries.
 

Structural Features


  • ExternalTankDesign

The plastic pump body is vertically installed on the outside of the storage tank. Only the impeller, pump shaft and sheath are immersed in the medium (the immersion depth is usually 0.5m below the liquid surface), while the motor and bearing assembly are located above the liquid surface.

  • VerticalStructure

The pump body is installed vertically, occupying a small area and is suitable for occasions with limited space.


 

Working Principle


  • The motor drives the pump to rotate through the long shaft, causing the impeller to rotate synchronously. A negative pressure zone is formed at the center of the impeller.
     
  • The medium is sucked in through the suction port, accelerated by the impeller, and then discharged from the discharge port, achieving continuous circulation of the liquid.

 

Application Scenarios


  • ChemicalIndustry

It is used for transporting corrosive liquids, such as acids, alkalis, salt solutions, etc.

  • ElectroplatingIndustry

For the circulation of the liquid in the plating bath and transmission, such as chemical liquid copper, gold plated, nickel plating solution, etc.

  • EnvironmentalProtection

Sewage treatment, waste gas scrubber and other equipment used for the liquid circulation and transmission.
