It is suited to domestic, commercial, or light industrial use where the shower outlets are positioned below the cold-water storage tank. The pump is typically installed in an airing cupboard or loft space, close to the water supply. Regenerative Pump Design for Complex Plumbing Routes: Unlike standard centrifugal pumps, this unit uses a regenerative pump design, which makes it well equipped to overcome air pockets in the pipework. This is particularly useful where the plumbing route includes multiple bends and elbows. The continuous duty rating means the pump can run for extended periods without interruption. Brass Construction for Long-Term Reliability: The pump is built with brass impellers and machined brass stampings, which offer greater durability than plastic-bodied alternatives. Long-life silicon carbide seals reduce wear over time and contribute to the low-noise operation. The motor housing is finished in black, with brass pump heads providing a solid, hardwearing build throughout. Quiet Operation with Built-In Protection: Anti-vibration feet are fitted as standard to reduce noise and vibration during operation. A built-in integrated thermal protection system stops the motor automatically if it overheats, protecting the pump from damage. The quiet induction motor and minimal turbulence pump head design keep operating noise to a minimum during use.
