Application Industries

A white symbolic image with a power plant and smokestack represents energy generation. The background is blue.
A white symbolic image showing a plant with three leaves around which an electrical cable with a plug is wrapped represents the renewable energy industry. The background is blue.
A white symbolic image depicting a refinery with an oil tank, steel tower, and flame represents the refinery, oil, and gas industry. The background is blue.
A white symbolic image of an offshore oil rig represents the offshore industry. The background is blue.
A blue symbol with a chemical compound represents the chemical industry.
The fertiliser industry is represented by a blue symbol showing a pile of earth with a plant growing out of it and fertiliser spread over it.
A blue symbol image with factories symbolises general industry.

Due to heavy-duty between bearings design, lowest NPSH values, and highest energy efficiency the pumps of this range are suitable for a variety of applications:

  • applications in the oil and gas industry
  • offshore engineering
  • power plants
