JS150SV Sewage Vortex Pumps
The JS-150SV sewage vortex pump is the smallest pump in the JS Pumps SV family: a compact 1¼-inch submersible for light duty sewage, foul water, dirty water and clean water. It moves up to 125 litres per minute, lifts to a maximum head of 6.5 metres and passes soft solids up to 25 mm, all from a 0.15 kW single-phase motor. At around 5.5 kg it is easy to lift in and out of a small sump.
A vortex impeller is recessed above the inlet, so it sets the liquid spinning rather than pushing every solid through the blades. That gives soft solids an easier path and reduces the risk of blockage. The JS-150SV is built light, with a plastic pump body, impeller, motor lid and lower motor and bearing housing, a single silicon mechanical seal, 10 metres of cable and a 1¼” BSP female outlet with a 1¼” male hose tail.
Choosing a JS-150SV: manual, MAC-3 or Agma
Pick the voltage first. Each version comes in 230v for mains power or 110v for a site transformer, and performance is the same on both.
Then choose how the pump is switched. The JS-150SV manual runs whenever it is powered, so use it where someone is on hand or wire it to your own float switch or control panel. The JS-150SVA comes with a MAC-3 float switch on a tethered cable that starts and stops the pump with the level, ideal where the sump has room for the float to swing. The JS-150SVAG uses an Agma level switch mounted on the pump body.
Install the pump standing upright, never on its side, and no deeper than 7 metres. Size it against the curve: at 6.5 metres the flow falls to nothing, while at 2 metres of head the pump still delivers around 100 litres per minute.

Where to Use a JS-150SV Sewage Pump
The JS-150SV is made for small sumps with light duty sewage or waste water: a utility room, shower or sink waste pit below the drain, a small cellar sump, or a pit serving a garden room or outbuilding. Its 1¼-inch outlet and 25 mm solids rating suit modest flows rather than a busy toilet stack, and at 125 litres per minute it empties a small pit quickly without oversizing the discharge pipe. Our guides on how to choose a sewage pump and the difference between a sewage pump and a sump pump will help you decide whether this is the right class of pump.
The 110v versions run from a standard site transformer, so they are handy on construction sites for small welfare and cabin sumps, dirty water in shallow pits and draining down. Because the pump is light and fitted with a hose tail, it is quick to move from one job to the next.
Check the lift before you buy. Maximum head is the height at which flow stops, so read the curve at your real lift and pipe length; our guide to reading a pump curve shows how. For bigger duties on a three-phase supply, the JST SV 400v range uses the same vortex principle in cast iron.
Frequently Asked Questions
What can the JS-150SV pump?
JS rates it for light duty sewage, clean water and dirty water, with soft solids up to 25 mm. It is not built for heavy solids, rags or oils and chemicals. If your sump takes waste from a well used toilet, a pump with a larger outlet, such as the JS-250SV (solids up to 36 mm) or a 2-inch JS SV pump, gives more margin.
What is the difference between the JS-150SVA and the JS-150SVAG?
Both are automatic. The JS-150SVA has a MAC-3 float on a tethered cable, which needs room to swing in the sump. The JS-150SVAG has an Agma level switch mounted on the pump body; JS lists it 22 mm longer than the standard pump. Performance is identical.
Should I choose the JS-150SV or the JS-250SV?
Choose the JS-150SV for small, light duty sumps where a 1¼-inch discharge is enough. The JS-250SV steps up to a 1½-inch outlet and a cast iron pump body, and passes soft solids up to 36 mm, so it gives you more margin where solids are larger or the pump works harder.
Can the JS-150SV run on a 110v site supply?
Yes. All three versions (manual, MAC-3 and Agma) are available in 110v as well as 230v, with the same performance. The 110v pump draws 2.8 A, against 1.4 A at 230v, so it puts only a light load on a site transformer.
How should the JS-150SV be installed?
Stand it upright on a firm base in the sump. JS states that it must not be installed lying on its side, and the maximum immersion depth is 7 metres. The 1¼” BSP female outlet takes the supplied hose tail or a threaded fitting; our guide to pump discharge pipe size covers the pipework.
