JS-650SV 110v Automatic 2″ Sewage Submersible Pump

Description

The JS Pumps JS-650SV 110v Automatic (code 011-702A) is the high-head model of the 2-inch JS SV pumps: a cast iron submersible sewage pump with a vortex impeller. It delivers up to 360 litres per minute and lifts to a maximum head of 12 metres, through a 2″ outlet, on a 110v site transformer, drawing 11 A at full load.

This is the automatic version, fitted with a MAC-3 float switch that starts the pump as the level rises and stops it as the sump empties. Allow roughly 300 mm of clear space around the pump so the float can swing freely. The JS-650SV 110v Manual is the same pump without the float, for use with your own controls. For lighter duty with a shorter lift, the JS-400SV 110v Automatic gives 260 l/min to 7.5 m. Where volume matters more than height, the JS-750SV 110v Automatic delivers 450 l/min to 8 m 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)
• Single-phase motor, 110v, 11 A
• Up to 360 l/min and 12 m head
• 2″ side vertical outlet with hose tail, removable for a coupling foot
• MAC-3 float switch for automatic operation
• 10 metres of power cable

Applications

• Site welfare cabins and temporary toilet blocks on 110v
• Sumps where the discharge point is well above the pump
• Sewage and foul water transfer on construction sites
• Dirty water and drainage sumps on site
• Plant hire fleets that need a sewage-rated pump
• Unattended duty where the pump must switch itself

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.
