Danube Shower Booster Pumps

Grundfos Watermill Low Voltage power shower pumps


The Grundfos Watermill Danube Shower Pumps are a range of Low Voltage pumps. As such, these are arguably one of the safest shower pumps available in the UK. They are even safe enough for under-bath installation if needed.

The Danube range is fitted with long-life carbon graphite seals and high density ceramic seals and is designed specifically for domestic shower and bathroom applications, the Danube range comes with stainless steel flexible hoses, a transformer and a comprehensive 2 year warranty. 'Manual negative head kits' are available from Grundfos.

The installation of a Grundfos Surrey flange is recommended. (For information: A Surrey Flange should be fitted to any hot water cylinder that does not have dedicated power shower take-offs fitted. This device installs in the top of your hot water cylinder. The flange provides a draw-off point for hot water that will feed to the pump at a lower level than the normal hot water outlet at the top of the cylinder - hence avoiding the likelyhood of air bubbles being sucked into the pump where they would cause impellor to cavitate.)


Features of Danube Low Voltage pumps:

  • Safe enough for under-bath installation
  • Anti-vibration feet
  • Long-life carbon graphite seals and high density ceramic seals
