VPH Vertical propeller pump, suspended

For the highest delivery rates

This vertical tubular casing pump has supports or is installed on a reinforced concrete floor with a supporting frame. Its use is recommended in cases where there is no solid pumping station bed to accommodate the vertical version (VP) or the bed is too deep down.
 
This propeller pump achieves the highest delivery rate of all KÖSTER pumps. It is suitable for the conveyance of pure or pre-treated, predominantly chemically-neutral fluids at temperatures of up to 60°C. This type of pump is used primarily in pumping stations for irrigation and drainage, for precipitation and mixed water, in waterworks and in industrial water supply systems.

 
 

 
 

Characteristics

  • The propeller blades fixed to the hub of the propeller can be rotated individually allowing subsequent adjustment of the blade angle and therefore also the duty point of the pump
  • The manifold can be arranged both above or below the floor
  • The pump can operate in the reverse direction for a short time (approx. 20 seconds). This frees the impeller of any foreign matter. This in turn remedies approx. 80% of all failures arising from clogged impellers without having to dismount the pump
  • We offer the shaft guide bearings with pumping medium lubrication and supply them in three different material pairs. Grease lubrication is also possible
  • Depending on requirements we produce the propeller blades and shaft in different materials, these range from grey cast iron to super duplex stainless steel
  • A multiple segmented manifold is used for streamlined redirection of the pumping medium An hydraulically optimised inlet connection accelerates the pumping medium with minimum turbulence
  • A large shaft diameter and sufficient intermediate bearing ensure extremely smooth running
  • The preserving agent differs according to customer demand and is always applied in several coats by hand
