The CH Boostamatic 4-50 B Universal Shower Pump 5.0 bar Single Impeller is designed for use in larger domestic and light commercial applications. Installed into an open vented hot or cold water system, where the outlets are either above or below the level of the cold water cistern, it has the equivalent effect of raising the cold water cistern 13 metres above its current position with a flow rate of 45 litres per minute.
Applications include boosting water pressures to individual outlets such as mixer taps and shower valves where a medium pressure is required. This pump is ideal for use in pairs, boosting hot and cold water services to multiple outlets in large houses, schools or leisure centres. This single shower pump has been designed to provide a pressurised water supply from a break tank in either a positive or negative head application.
A negative single pump can be used to:
*supply vented hot and cold services (if two pumps are used) in large houses or multiple outlet systems.
*feed unvented systems from a break tank.
22mm Push-In Flexible Connectors (2 Included)
Flow and pressure switch operation
Approximately 1.0 l/min Flow Switch Sensitivity
22mm Push-In Plumbing Connection
WRAS Approved Shower Pump
This shower pump has one incoming water supply. Please check that you require a single impeller positive or negative head shower pump before placing your order.

Why fit a flange?

A flange reduces air being sucked into the pump which prolongs the life of your pump, and it can make installation much easier.
Why install the optional Pump Mat?

The addition of an anti-vibration mounting pad provides improved sound insulation further reducing the transfer of motor noise and vibration.
