  • Exempt photo of a ZMLK Apollo pump unit, an axially split, single-stage centrifugal pump with bearings on both sides.

    ZMLK01

  • A blue-painted ZMLK centrifugal pump unit with motor, switchboard, and accessories, placed in front of a test bench unit from Apollo Goessnitz, which will later be used in a petrochemical plant.

    ZMLK02

  • Two ZMLK pump units with motors placed one behind the other in the Apollo warehouse, which will later be used in a chemical plant.

    ZMLK03

Horizontal or vertical mounted, single-stage, double-suction, normal-priming, horizontal split centrifugal pump, type ZMLK. The pumps are available as units with base plate or base frame and contact protection according to DIN.

Split-casing centrifugal pumps of the ZMLK series are preferably used for pumping raw, cooling and seawater in the following branches:

  • water treatment
  • water supply
  • environmental technology
  • ship building industry
  • power stations
  • single-stage, split-casing normal suction pump with double shaft bearing
  • due to the double-flow impeller, the pump operates almost without axial thrust
  • pump casing is horizontally split in the shaft level. For repairs, the pump casing can remain in the piping system, while the sealing system and rotor with impeller can be dismantled
  • impellers can be adapted to the operating point 
  • vertical types, close-coupled types and cardan shaft driven pumps are available upon request
  • grey cast iron
  • ductile iron
  • bronze
  • cast steel
  • stainless steel
