Monsoon Universal 3.0 bar Twin - Shower & whole house pumps

Monsoon Pumps

Monsoon Universal 3.0 bar Twin pumps are designed for installation into vented systems to pump both the hot and cold water supplies - boosting both equally. Suitable for both positive and negative head applications.

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


  • Boost hot and cold water services to the complete home, bathroom, kitchen or cloakroom.
  • Pressurise the supply in applications such as loft conversions, where outlets are higher than the water source.

* The maximum pressure that can be applied to the pump under any installation conditions.

** A stored water temperature of 60 °C is considered sufficient to meet all normal requirements and will minimise deposition of scale in hard water areas.

*** Both heads pumping 4.5 l/min and above.
