KRAL Screw Pumps for Machinery Lubrication.

KRAL three-screw pumps provide high reliability and efficiency for crucial process machinery lubrication.

In addition to the traditional horizontal mount, KRAL pumps are available in freestanding vertical configuration as well, saving valuable space on the lube skid. Pumps are available in iron or steel case configuration.

Flow range from 1 to 900 gpm and discharge pressure to 1,450 psi can be attained at nominal motor speeds without the requirement for speed reduction gears. The pumps can also be directly mounted on an auxiliary shaft from the rotating machine being lubricated at speeds up to 6,000 rpm, provided a sufficient suction pressure level to avoid cavitation.

The low velocity and pulse free flow of the KRAL pump assures low noise operation and freedom from cavitation.

Your advantages:

  • Quiet pulse free operation.
  • Hydraulic balance.
  • Ability to operate at high speed.
  • High efficiency.
  • Long term reliability.
