Pneumatic Barrel Pump

Our company is actively engaged in producing Pneumatic barrel pumps which works in reciprocating action. This pump is useful for safe and efficient handling of highly corrosive chemicals, solvents, acids, petroleum products, diesel oil, and fuel oils, plating solution, toxic chemicals etc. It even eliminates danger of spillage, explosion hazards.

Our construction of pump has been given such that operating compressed air never gets in contact with pumped liquid. The pump can be directly inserted in to the barrel and fits on the bung hole by means of threading provide on the pump adopter. It sucks the liquid from the bottom and hence less chances of leftover material. It does not have any type of motor and hence virtually zero maintenance. Following are its advantageous benefits:

  • Operates on compressed air of 4 to 6 Kg/Cm².
  • Adjustable flow rate.
  • Self-priming
  • Easy to lubricate.
  • Less maintenance
  • Light weight.



Following are its other technical specifications:

Capacity 40 Lpm.
Head 15 Mtrs.
Operating Pressure 3 to 6 kg/cm²
Material of construction S.S.304 / 316
Discharge 1 Inch
Temperature 120° C
