Description
The JS Pumps GS-1200 110v Manual (code 020-704) is the site-voltage version of the GS-1200 sewage grinder pump, for use from a 110v transformer. It delivers up to 190 litres per minute and lifts to 19 metres of head through a 1ΒΌ” outlet, with a 1.2 kW motor and a cutter and high-chrome grinder ring that shred soft solids before pumping.
At 110v the motor draws 20 A, which is more than a standard 16 A 110v outlet supplies, so make sure your transformer and socket are rated for the load. Being manual, it runs whenever it is switched on, which suits an attended welfare tank or a chamber with separate level control. The GS-1200 110v Automatic adds a MAC 3 float switch, and the GS-1200 230v Manual is the mains-voltage equivalent.
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.
