Description
The JS-150SV 230v Automatic MAC-3 (code 011-150A) 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 standard 230v single-phase mains supply, drawing 1.4 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 230v Automatic Agma does the same job with a level switch fixed to the pump body, and the JS-150SV Manual 230v is the same pump without a float, for use with your own controls. The same pump is available on 110v as the JS-150SVA 110v 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. Remember that 6.5 metres is the head at which flow stops; the curve below shows how much the pump moves at your actual lift.
