Product Overview
Building services engineers specify the factory-matched hydraulics and integrated drives of the Davey Monsoon Light vertical multistage booster package. Equipped with a vertical multistage pump assembly, the unit sustains line pressure stability across demanding plumbing lines. This packaged assembly supplies an integrated booster solution to prevent pressure dropouts across elevated risers.
Under varying plant load conditions, total discharge volume smoothly scales up to 142 L/min. Across elevated vertical distribution lines, the multistage hydraulic wet end generates up to 157 metres of maximum shut-off head to overcome static elevation losses. Internal impellers and intermediate stage diffusers are manufactured from AISI 304 stainless steel to maintain fluid purity and hydraulic efficiency. A hard-faced mechanical seal and reinforced casing construction support operating system pressures up to 25 bar (2,500 kPa PN25).
Mechanical power is supplied through a precision induction motor designed for commercial duty. Speed regulation is governed by an integrated variable frequency drive controller, continuously matching motor speed to instantaneous draw to stabilize pipeline pressure. The electrical package connects to a 415V supply at 50 Hz drawing a rated current of 5.8 Amps. Pre-plumbed hydraulic connections feature standardized 1-1/4" BSP ports, rated for clean liquid operating temperatures from 0°C to 40°C.
The complete unit is factory-aligned and secured to a rigid structural steel skid. Integrated elastomeric mounts isolate pump vibrations, protecting connected distribution pipework from mechanical stress and acoustic transmission. Engineered and assembled to meet demanding Australasian commercial plumbing standards, the system benefits from comprehensive Davey technical support and readily available nationwide spare parts.
