Description
The JS JST-15H 400v (code 011-019) is a three-phase high head heavy duty submersible drainage pump for clean and dirty water. It delivers up to 450 litres per minute and a maximum head of 23 metres from a 1.5 kW motor, through a 2-inch outlet, on a 400v three-phase supply. This is the high head version of the JST-15. It uses the same 1.5 kW motor on a 2-inch outlet, giving 23 metres of head against 18 metres for the standard JST-15, at a slightly lower flow.
It is a manual pump, so it runs whenever power is applied. JS states that every JST model can be made to run automatically with a three-phase control panel and float switches; see our pump controls and float switches. In the same range, the JS JST-15 is the standard version, 500 l/min to 18 m on a 3″ outlet, and the JS JST-22H is the next high head model, 650 l/min to 30 m.
Like every pump in the JST range, it has a stainless steel shaft and motor case, with a cast iron motor top cover, lower motor and seal housing, pump case, impeller and volute. Twin mechanical seals (carbon ceramic and silicon carbide) run in a lubricated chamber, and the pump comes with 10 metres of power cable. A hose tail is supplied for the outlet.

The JST range is for clean and dirty water containing small solids such as silt, sand and grit. It is not designed for raw sewage, rag or fibrous material, heavy slurry, oil or chemicals: for sewage on a 400v supply see the JST SV sewage vortex pumps, and for sand-laden water and slurry see the JST KB slurry pumps. It needs a 400v three-phase supply and, like any standard submersible, stops drawing once the water falls below the intake.
