End Suction Pumps

End Section Pump

Your advantages

  • Reduced life-cycle costs through optimized efficiency levels
  • Bidirectional, force-flushed mechanical seal
  • Low NPSH values, best cavitation properties
  • Shaft coupling with or without spacer coupling



Single-stage, low-pressure centrifugal pump with axial suction, mounted on a baseplate.


  • Pumping of heating water (acc. to VDI 2035), cold water and water/glycol mixtures without abrasive substances in heating, cold water, and cooling systems.
  • Applications for irrigation, building services, general industry, power stations, etc.


Single-stage low-pressure centrifugal pump in monobloc design with coupling, coupling guard, motor, and baseplate

  • Mechanical shaft seal or stuffing box
