Air Driven Liquid Pumps

Haskel Air Driven Liquid Pumps

Haskel air driven pumps offer many advantages over conventional electrical driven units as follows:

  • Ability to install at any predetermined pressure and hold this fixed pressure without consuming power or generating heat.
  • No heat, flame or spark risk.
  • Infinitely variable cycling speed output.
  • Up to 100,000 psi (7,000 bar) pressure capability.
  • No limit or adverse effect to continuous stop/start applications.
  • Air drive does not require an external line lubricator thus saving on running cost and preventing oil vapor contamination of the surrounding environment.
  • Reliable, easy to maintain, compact and robust.

Key Features:

  • Wide range of modifications and control options.
  • Noise reduction kits for selected models.
  • Unbalanced cycling spool provides immediate operation in response to output pressure change.
  • Suitable for large variety of liquids and liquefied gases.
  • Bottled gas, boil off from a liquefied tank or natural gas can be used as an alternative to air drive.
  • Range of standard and specially built systems.
  • Ability to design and manufacture systems to customer specifications.
