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

Sectional drawing of an Apollo KGR (horizontal, high-performance, radially split, two-stage, intermediate-bearing process pump) designed with an inducer.
  • Inducer is an additional upstream impeller of screw type which provides very low NPSH values
  • Design of the inducers is selected according to specific application range of Customer.
  • In case of double-flow impeller upstream inducers are applied on both sides.
