Product Overview
Engineered for commercial boosting duties, the Davey Monsoon Light vertical multistage booster package delivers responsive water supply. 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.
Engineered for extended maintenance-free service, peak hydraulic volume reaches 383 L/min. Across elevated vertical distribution lines, the multistage hydraulic wet end generates up to 54.7 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 16 bar.
Power delivery is handled by an electric induction motor built for variable frequency modulation. 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 7.8 Amps. Pre-plumbed hydraulic connections feature standardized 2" BSP ports, rated for clean liquid operating temperatures from 0°C to 40°C.
Designed for easy maintenance access, the package rests on an open-frame 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.
