Monsoon Universal 2.0 bar Single - Shower & whole house pumps

Monsoon Pumps

Monsoon Universal 2.0 bar Single pumps can be used in pairs to boost vented systems to pump hot and cold water supplies independently, or as a single pump to boost a water supply as required. Suitable for both positive and negative head applications.

Monsoon Universal pumps do not require a gravity flow of water to start. 


  • Boosting hot water services to a common mixer where the cold supply is mains fed.
  • Boosting hot and cold supplies separately.
  • Increasing water pressure to a combi boiler via a break tank.
