Description
Compact booster pump set designed to boost pressure for tall buildings where the mains supply is inadequate, e.g. penthouse suites. The unit is supplied as a complete package on a stainless steel base plate ready for installation. The set is approved for drinking (wholesome) water applications since it has a screened overflow and vent, conforming to G16.13. The primary purpose is to boost the water pressure for elevated areas or where a high flow rate is required, e.g. for showers or baths. The performance to compactness ratio often enables the unit to be installed in a ground floor cupboard rather than a full size plant room. Frequently one unit per luxury apartment is used. The unit is quiet by virtue of a centrifugal pump, anti-vibration rubber feet and flexible stainless braided connection hoses. Fast filling is acheived by a servo-controlled solenoid valve with solid-state level probe control. This system has proved to be more reliable and accurate than conventional float valves. The small cistern and high throughput minimises the risk of legionella.
