Description
The JS-530 Well Buddy 230v Manual (code 011-530) is a multistage submersible pump from JS Pumps for clean water at high pressure. 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 manual version has no float switch: it runs whenever it has power. That makes it the one to choose when you will switch the pump yourself, or when you want to connect it to your own control, such as a pressure switch for supplying water on demand. If you want the pump to start and stop with the water level, the JS-530 230v Automatic is the same pump with a float switch. For a site on 110v, see the JS-530 110v Automatic.
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. Because it has no float switch, it will keep running if the water level falls below it, so use it only where you can control it or protect it against a low water level.
