JS GS-1200 230v Manual Sewage Submersible Pump

Description

The JS Pumps GS-1200 230v Manual (code 020-702) is a single-phase submersible sewage grinder pump for mains-powered installations. A cutter working against a high-chrome grinder ring shreds soft solids before they reach the impeller, so the pump can deliver up to 190 litres per minute and lift to 19 metres of head through a 1¼” outlet, driven by a 1.2 kW motor drawing 9.9 A at 230v.

As the manual version it runs whenever power is applied, which suits a sump controlled by your own float switch or a control panel. If you want the level control built in, the GS-1200 230v Automatic is the same pump with a MAC 3 float switch. For longer or higher discharge runs, step up to the GS-1500 230v Manual, which lifts to 22 metres.

The pump body, impeller, motor top cover and lower bearing and seal housing are cast iron, and the motor case is stainless steel. Twin mechanical seals (carbon ceramic and silicon carbide) run in a lubricated oil chamber. The side vertical outlet is removable, so the pump can stand free with the hose tail supplied or sit on a guide rail coupling foot for easy lifting out. It comes with 10 metres of power cable.
