Description
The JS RS-550 110v top outlet drainage pump (code 010-552) is a submersible drainage pump with a top outlet, for clean and dirty water with small solids. It pumps up to 280 litres per minute and reaches a maximum head of 11 metres from a 0.55 kW motor on 110v, the reduced-voltage supply used on UK construction sites through a site transformer. It is the first of the heavier RS models, with a cast iron impeller and a larger motor for continuous site work.
It runs whenever it has power. For automatic operation add a Mouse or AGMA float switch, which switches the pump on as the water rises and off before it runs dry. The JS RS-550 230v is the same pump for 230v single-phase. The JS RS-750 110v is the next size up, 345 l/min to 15 m.
The top outlet keeps the pump slim, so it fits down narrow sumps and chambers and sits upright on a flat floor. Inside, twin mechanical seals (carbon ceramic and silicon carbide) run in a lubricated oil chamber to protect the motor. The outer case, shaft and motor case are stainless steel, and the volute, motor top cover and lower bearing and seal housing are cast iron. The RS-150, RS-250 and RS-400 have a plastic impeller; the RS-550 and RS-750 have a cast iron impeller. Every pump comes with 10 metres of power cable and a hose tail, passes solids up to 6 mm and can be submerged to 7 metres.
