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. Maximum suction lift, with a foot-valve, is 7 metres.
