The Protex Proflush Power Flushing and Descaling Pump is designed for flushing central heating systems to resolve circulation and boiler noise problems caused by the accumulation of sludge, corrosion deposits and scale. The unit can be fitted with an optional magnetic filter to speed up the power flushing process. The filter can be permanently mounted in the heating system or be used together with the Proflush pump. The magnet is removable therefore avoiding direct contact with the hands. The built in flow management forces water to flow over the fins, thus maximising the iron oxide retention over an increased surface area.
