                  Electric Submersible Borehole Pumps
The Rovatti E-ER Electric Submersible Borehole pumps range in sizes from 4" to 14" diameter to cover duties between 0.3-540 m3/hr with pressures up to 70 bar.4ER_E_Electric_Submersible_Borehole_Pumps

They are installed throughout the world, often under the most exceptionally demanding conditions, and suitable for many applications including:

  • Borehole water supply
  • Pressure boosting
  • Irrigation systems, greenhouses and gardens
  • Fire fighting
  • Light chemical industry
  • Marine applications
Construction

Every borehole pump is engineered to the highest standards to ensure maximum operational efficiencies over a long maintenance free life.

All materials used are non-pollutant and resistant to both wear and tarnishing.  Plastic components are specially formulated to comply with international norms.

Vertical operation is standard, however, many pumps within the range can operate horizontally and full details on this facility and many other specialist options are available on request.

 

Submersible Motors

The single and three phase submersible motors used are of well know international brands.  As they are standardised, the motors are perfectly interchangeable so maintenance and repairs are greatly simplified.

Three-phase asynchronous type motors are available from 4" up to 12" sizes

Water fitted (6" to 12") or oil filled (only 4") motors are available in both re-windable (4" to 12") and encapsulated (4" to 6") versions. Radial and thrust bearings are lubricated by the same motor liquid.

E-ER Borehole pump series
Cast-iron construction as standard

'Black' versions
Pump bodies and all parts in contact with pumped liquid are Cataphoresis treated.  Opaque black colour.  Cataphoresis is a special electro-chemical protective coating for better wear life.

'Black-X' versions
As above but also supplied with AISI316 cast steel impellers
