  • Monoblock external gear pump.
  • The helical gears allow a smoother and quieter operation of the pump.
  • It is a self-priming pump. That is to say, with the installation empty, the pump is able to aspirate the liquid causing a vacuum pressure in the suction pipe.
  • The design integrates a built-in safety valve in the gear casing that is capable of relieving the pressure in case the working limits are exceeded.
  • Suitable for transferring fuel oils, lubricants, animal or vegetable fats and others.
  • Compact monoblock construction with single motor-pump shaft. Elias Pump also offers different series of gear pumps with standard IEC motor and a series on baseplate with motor.
  • Sealing solution with mechanical seal or lip seals depending on the model and the application.
