Description
The JS Pumps JS-400SV 230v Manual (code 012-410) is the entry point of the JS SV single-phase range: a compact cast iron submersible sewage pump with a vortex impeller. It delivers up to 260 litres per minute and lifts to a maximum head of 7.5 metres from a 0.4 kW motor, through a 2″ outlet, on a standard 230v single-phase mains supply, drawing 3.8 A at full load.
This is the manual version, so it runs whenever it is switched on. Use it where someone is on hand, or wire it to a separate float switch or control panel for unattended duty. The JS-400SV 230v Automatic is the same pump with a MAC-3 float fitted for automatic operation. If you need more lift, the JS-650SV 230v Manual reaches 12 m on the same 2-inch outlet, and the JS-750SV 230v Manual moves 450 l/min through a 3-inch outlet.
Every JS SV pump shares the same construction: a cast iron pump body and vortex impeller, a cast iron volute, motor top cover and lower bearing and seal housing, and a stainless steel shaft and motor case. Twin mechanical seals (carbon ceramic and silicon carbide) run in a lubricated oil chamber. The side-mounted outlet points vertically upwards and can be removed to fit a coupling foot for guide rail installation, and each pump comes with 10 metres of power cable and a hose tail.
JS Pumps also lists Class F motor insulation, a shaft sleeve to reduce wear, an additional lip seal that keeps grit away from the mechanical seals, thermal overload protection and an improved cable entry seal for this model.
Features
- Cast iron pump body, volute and vortex impeller
- Vortex impeller sits clear of the flow, so soft solids pass through with less risk of blockage
- Passes soft solids up to 35 mm
- Twin mechanical seals (carbon ceramic and silicon carbide) in a lubricated oil chamber
- Thermal overload protection (JS Pumps specification)
- 0.4 kW motor, 230v, 3.8 A
- Up to 260 l/min and 7.5 m head
- 2″ side vertical outlet with hose tail, removable for a coupling foot
- Manual operation (add a float switch or panel for unattended use)
- 10 metres of power cable
Applications
- Sewage and foul water sumps in houses, annexes and outbuildings
- Commercial and light industrial waste water pits
- Basement and below-ground drainage carrying soft solids
- Dirty water and drainage
Built for sewage, foul water, dirty water and drainage containing soft solids. A vortex pump does not cut or macerate, so it is not the right choice for small-bore pressure pipework; for that, look at the JS GS grinder pumps. It is not designed for oils, fuels, solvents or chemicals. If the water has a long way to travel or a high lift, check the curve: at 7.5 m maximum head this is a short-lift pump.
