Heavy-duty, radially split, double-stage process pump, between bearing version according to API 610 or ISO 5199. The double-flow suction impeller ensures for best NPSH values and the optimum rotor dynamics for safe operation. The suction impeller type KGR has a single-flow impeller.

 KGR
Q (m³/h)1 600
H (m)600
P (bar)80
T (° C)+400

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
KGR: BB2 pump - characteristic curve field visualizes pressure-volume flow relation.
  • Q= 1600 m³/h
  • H= 600 m
  • P= 80 bar
  • T= + 400°C

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.
