Mains Boost Pump

Where mains water pressure is less than 2.0 bar a Mainsboost Charger pump is the solution. Mainsboost Charger pumps will boost pressure up to 3.5 bar when supplied in conjunction with Mainsboost steel or composite vessels and can be located remotely from the Mainsboost vessel without restricting performance. Mainsboost Charger wall mounted pumps are supplied within a noise reducing enclosure.


Please note that Mainsboost Charger pumps are not available as a stand alone purchase and must be ordered in conjunction with a Mainsboost vessel system.
