Product Overview
Regional healthcare infrastructure chooses the hydraulic precision 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.
Controlled speed variation allows the system to output flows up to 483 L/min. Across elevated vertical distribution lines, the multistage hydraulic wet end generates up to 146 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).
Power is delivered via an industrial induction motor built with high-grade electrical laminations. 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 21.4 Amps. Pre-plumbed hydraulic connections feature standardized 2" BSP ports, rated for clean liquid operating temperatures from 0°C to 40°C.
Engineered to withstand pipework stresses, the unit is anchored to a rigid steel chassis. 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.
