Description
The JS-150SV 110v Automatic MAC-3 (code 011-152A) is the automatic version of JS Pumps’ smallest sewage vortex pump, supplied with a MAC-3 float switch on a tethered cable. It delivers up to 125 litres per minute and lifts to a maximum head of 6.5 metres from a 0.15 kW motor, passes soft solids up to 25 mm through its 1¼-inch outlet, and runs on a 110v site transformer, drawing 2.8 A.
The MAC-3 float rises with the liquid to start the pump and drops as the sump empties to stop it, so the pump looks after itself. A tethered float needs room to swing, so check your pit leaves clear space around the pump. In a tight sump, the JS-150SVAG 110v Automatic Agma does the same job with a level switch fixed to the pump body, and the JS-150SV Manual 110v is the same pump without a float, for use with your own controls. The same pump is available on 230v as the JS-150SVA 230v Automatic MAC-3.
If you need more than the JS-150SV can give, the JS-250SV moves up to a 1½-inch outlet with a cast iron pump body, and the JS SV single-phase range runs from 2-inch to 3-inch pumps for larger sumps and longer lifts.
The JS-150SV is built light. The pump body, vortex impeller, motor lid and lower motor and bearing housing are all plastic, and the motor is sealed by a single silicon mechanical seal. It comes with 10 metres of power cable and a 1¼” BSP female outlet, supplied with a 1¼” male hose tail. JS states a maximum immersion depth of 7 metres, and the pump must stand upright: it must not be installed lying on its side.

This is a light duty pump. It is not built for heavy solids, rags or continuous commercial sewage loads, and it does not cut or macerate, so it is not a match for small-bore pressure pipework; for that, look at the JS GS grinder pumps. It is not designed for oils, fuels, solvents or chemicals. On site, make sure the pump stands upright on firm ground in the sump rather than lying on its side in the mud.
