Davey HP45-05T and HP65-06T twin-stage pressure pumps provide automatic clean-water supply for household use, irrigation, water transfer and washing systems. Their Torrium2 controllers start and stop the pumps as water is used.
Both pumps use a 1 1/4" BSP female inlet and deliver through a 1" BSP male Torrium2 outlet.
They handle clean, non-volatile liquids without fibres or solids at water temperatures from 1°C to 50°C.
The supplied Torrium2 controller automatically starts the pump when water pressure falls and stops it when water demand ends. It automatically sets the starting pressure to suit the pump and installation, adapting during very low demand to reduce repeated starts. Its built-in accumulator allows a small amount of water to be drawn before the pump restarts.
The two-stage pump design uses a 304 stainless steel casing and backplate, glass-filled Noryl stage body and glass-filled polycarbonate impellers. The motor shell is marine-grade aluminium with a baked polyester finish.
Loss-of-prime protection stops the pump if its water supply is lost, with automatic retry to check whether water has returned. The controller also provides high-water-temperature and excessive-current cut-outs. The motor has its own automatic-reset thermal overload protection.
Install horizontally on a firm base in a ventilated, weather-protected position with drainage. Fill the pump casing and suction line with water before starting. Suction-lift installations require a foot valve to retain prime. The maximum suction lift is 6m; actual performance depends on the suction pipework and installation.
Each complete pressure system has a 450kPa maximum system pressure limit and uses a 220-240V single-phase, 50Hz supply.
Two-year Davey warranty, subject to its terms.
