Description
The JS RSD 150 Puddle Buddy 230v (code 012-150) is a portable residue pump for clearing clean water from flooded rooms, garages and cellars at home. It delivers up to 100 litres per minute and a maximum head of 6.5 metres from a 0.15 kW motor, through a 1″ outlet, and plugs into a standard 230v socket, drawing 1.4 amps. JS’s catalogue says it starts pumping at around 2 mm of water.
This is the version for household use. If you need to run the pump from a site transformer, the RSD 150 Puddle Buddy 110v has the same performance on a 110v supply. For contractor work or regular flood clearance, the stainless steel cased JS RSD-400 residue puddle pumps are the heavier-duty choice.
Like every RSD 150, it has a plastic pump body and plastic impeller, which keep the weight to 5 kg, and a single mechanical seal and oil seal. The 1″ male top outlet comes with a step adapter female hose tail for 1″, ¾” or ½” hose, and an anti-air lock valve helps the pump in shallow water. It is supplied with 10 metres of power cable and measures 265 x 138 x 138 mm (H x W x L).
The pump is manual, so it runs whenever it is switched on. The 230v model can be made automatic with The Crab low level sensor probe, which rests on the floor beside the pump and is factory set to start it 5 seconds after detecting water and stop it 30 seconds after the water clears. When you use it this way, fit a non-return valve on the outlet so the water in the hose does not run back when the pump stops.
