Description
- Gear pump with standard motor.
- 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.
- Compact monoblock construction with rigid coupling to standard motor according to IEC standards. Bomba Elias also has different series of gear pumps with single motor-pump shaft (R Series) and on baseplate units with attached motor (EL (SB) Series).
- Sealing solution with mechanical seal or lip seals depending on the model and the application.
- The main difference from the R Series is the use of a standard IEC motor. This allows a cheaper, simpler and faster motor replacement. It also allows the pump to operate at slightly higher temperatures, up to 110ºC. However, its volume is increased comparatively.
- Finally, the R-U series can be assembled in ATEX version ( contact the technical department for specifications and dimensions).
