Description
The JS-530 Well Buddy 230v Automatic (code 011-530A) is a multistage submersible pump from JS Pumps with a float switch, for clean water at high pressure from wells, tanks and reservoirs. It delivers up to 140 litres per minute and a maximum head of 45 metres (4.5 bar) from a 1.3 kW motor, through a 1″ outlet, on standard 230v single-phase mains, drawing 5.8 A.
The float switch starts the pump as the water rises and stops it as the level falls, so you can empty or transfer water from a tank or well without standing over it. If you would rather switch the pump yourself or wire it to a pressure control, the JS-530 230v Manual is the same pump without a float. The JS-530 110v Automatic is this model for 110v site supplies. For a lighter plastic alternative on 230v, compare the Well Buddy 1000A and 1000P.
JS builds the JS-530 from stainless steel and cast iron parts. The 1.3 kW figure is the motor’s input power; its output at the shaft is 0.84 kW. The pump has a 1″ outlet with no hosetail supplied, measures 520 x 200 x 235 mm, weighs about 17 kg and comes with a 10 metre power cable. JS rates it for a maximum submersion depth of 7 metres and water temperatures from 0 to 40 °C.

For clean water only, with no suspended solids or abrasive material, so it is not a drainage or dirty water pump. It must not be allowed to run dry under any circumstances. Leave enough room around the pump for the float to move freely. At 200 x 235 mm across, it will not fit a narrow borehole.
