Horizontally or vertically mounted, single-stage, axially split process pump according to API 610 and ISO 5199. The heavy-duty process design of the ZMK pump ensures maximum reliability. The pumps are available as units with a base plate or base frame and protection against accidental contact according to DIN 31001. They ensure process-reliable sealing under a wide range of operating conditions.

The pumps of the ZMK series can be used for pumping neutral, alkaline, and acidic media with slurries and abrasive components and are preferably used for pumping raw, cooling, and seawater in the following branches:

  • water and wastewater
  • power and heating plants
  • oil and gas industry as process pumps
  • in mining for dewatering
  • for pressure boosting and water supply in municipal and industrial applications
