R-EL (SB)
Bare shaft gear pump

Bare shaft gear pump mounted on a baseplate with an electric motor attached.

The self-priming pump, with quiet helical gears, incorporates a pressure safety valve.

it is suitable for transferring fuel oils, lubricants and animal or vegetable fats.

Description

Description

  • Bare shaft gear pump, mounted on a baseplate with a electric motor attached with an elastic coupling.
  • 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 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.
  • The series is available in EL-Bare shaft without motor (R-EL) or SB-On basepalte with an electic motor attached with an elastic coupling (R-EL SB)
  • Sealing solution by means of a mechanical seal or lip seals depending on the model, in accordance with the application.
  • The SB-On baseplte version with motor includes a bare shaft gear pump mounted on a sturdy metal sheet baseplate with its motor attached by means of a properly protected felxible coupling.
  • Lastly, the R-EL (SB) series can be installed in explosive atmospheres in accordance with ATEX directives.

For monoblock versions, see the R and R-U series.
