The GPA90(S) is a booster set for water supply systems where space is at a premium. It incorporates a peripheral pump, pressure vessel and a pressure switch ready assembled for installation. With stainless steel connections and a butyl bladder, there is no water contact with the steel vessel creating an uncontaminated water path. Can be used for domestic water boosting and pressurised water supply of mobile toilets and shower blocks.
Motors have aluminium motor housing and pressed steel or plastic fan covers. Single phase motors incorporate an overload protection device. These pumps should not be allowed to run dry, but by fitting an optional pressure controller, they can be protected from this and also start and stop it automatically. With the addition of a foot-valve, they are capable of suction lifts of 8 metres.
