JS-530 Well Buddy Multi Stage Irrigation Pumps
The JS-530 Well Buddy is a heavy duty multistage submersible pump from JS Pumps for moving clean water at high pressure from traditional wells, rainwater harvesting tanks, collection tanks and reservoirs. It delivers up to 140 litres per minute and a maximum head of 45 metres (4.5 bar), enough to feed irrigation systems, run sprinklers over a large garden or lift water up to a header tank on higher ground.
JS builds the JS-530 from stainless steel and cast iron parts around a 1.3 kW motor, with a 1″ outlet and a 10 metre power cable. At about 17 kg it is a substantial pump, made for jobs where a lightweight plastic garden pump would be working at its limit.
Choosing a JS-530: manual or automatic, 230v or 110v
All three versions share the same pump end and the same performance. What changes is how the pump switches on and the supply it runs from.
The 230v manual (011-530) runs whenever it has power. Choose it when you will control the pump yourself, or when it will be wired to a separate control such as a pressure switch.
The 230v automatic (011-530A) has a float switch that starts the pump as the water level rises and stops it as the level falls. That suits emptying or transferring water from a tank or well without leaving the pump to run once the water has gone.
The 110v automatic (011-532A) is the same float-switched pump wound for 110v, for building sites and other workplaces that run tools from a 110v transformer. It draws 11.6 A against 5.8 A for the 230v versions, so check your transformer can supply it. There is no 110v manual version.
Not the same as the Well Buddy 1000A and 1000P. Despite the shared name, those are a separate range of lighter plastic pumps with 1.0 kW motors, 230v only. Compare them on our Well Buddy 1000A and 1000P page.

Where to Use JS-530 Pumps
The JS-530 is built for clean water jobs that need both volume and pressure. Typical uses are irrigation and sprinkler systems fed from a hand-dug well or spring, drawing harvested rainwater from an underground tank, moving water between storage tanks, and lifting water uphill to a header tank or trough. JS also lists it for home pressurisation, where the manual version is paired with a separate pressure control; call us if you want help putting that together. Our guide to choosing the right well pump covers the wider options.
Work out your duty before you order. The 45 metre maximum head is only reached at very low flow, and every metre of lift, every metre of pipe or hose and the pressure you want at the outlet all use some of it up. As a rule of thumb, 10 metres of head equals 1 bar. Read your required flow and head off the performance curve on the product page; our guide to pump head and flow rate shows how.
Know where the JS-530 stops. It is for clean water only, with no suspended solids or abrasive material, so it is not a drainage or dirty water pump. At 200 x 235 mm across it will not go down a narrow borehole: for 4-inch bores look at the Matra Venus borehole pumps, or browse all well and borehole pumps.
Frequently Asked Questions
Which JS-530 do I need?
On a 230v mains supply, choose the 011-530 manual if you will switch the pump yourself or connect it to your own control, or the 011-530A automatic if you want a float switch to start and stop it with the water level. On a site running 110v tools, the 011-532A is the only option and is automatic. Performance is the same on all three: up to 140 l/min and 45 m of head.
How is the JS-530 different from the Well Buddy 1000A and 1000P?
The JS-530 is a heavier stainless steel and cast iron pump with a 1.3 kW motor, rated to 140 l/min, and comes in 110v as well as 230v. The Well Buddy 1000A and 1000P are lighter plastic pumps with 1.0 kW motors, rated to 110 and 100 l/min, for 230v only. Both reach 45 m of head.
Can the JS-530 run dry?
No. The JS-530 must not be allowed to run dry under any circumstances, so keep it covered by water whenever it is running. If the water level can fall below the pump, choose an automatic version so the float switch stops it, or fit suitable level protection to the manual model.
How deep can it go, and how warm can the water be?
JS rates the JS-530 for a maximum submersion depth of 7 metres and water from 0 to 40 °C. Lower it on a rope attached to the pump rather than by its power cable, and keep it clear of sediment at the bottom of a well or tank.
What hose or pipe does it take?
The JS-530 has a 1″ outlet and no hosetail is supplied, so order a 1″ fitting to suit your hose or pipe. On long runs, a larger pipe loses less head to friction and leaves more pressure at the far end.
For help choosing a JS-530 or sizing it for your well or irrigation system, call the AES Rewinds team on 01252 515169 or email sales@aesrewinds.com. If you need to raise mains water pressure rather than draw from a well or tank, see our booster pumps instead.
