MRA-MT - Vortex pump

Recessed impeller pump with vortex action


Recessed impeller pump with vortex action

- Large shaft diameter reduces shaft deflection and vibrations to preserve the bearing’s life span.
- Shaft fully protected from the pumped liquid by the shaft sleeve and O-ring
- Screws entirely outside of the fluid and protected from abrasive and corrosive actions.
- The stuffing box is cooled and easily accessible.
- Various seal options are available: packing, single, double, tandem mounted mechanical seal or hydrodynamic seal .
- Non-clogging impeller.
- Wear of hydraulic components is limited. The impeller creates a vortex field in the casing which moves the fluid and solids minimizing contact with the hydraulic components.
- BACK PULL-OUT design: dismantling without disturbing the piping or the motor.
- Standard bearing protection by labyrinth type seal and deflector.
- Bearing housing with oversized oil lubricated bearings (or grease lubricated as an option) allowing V-Belt transmissions as well as direct transmission.
- Roller bearing’s life span is superior to 25.000 hours.
