Onga shallow and deep well jet pump range

The Onga 54, JJ and OJ range are the higher flow and pressure range of jet assisted, single impellor pressure pumps. These pumps are available as either a shallow well pump (with an inbuilt jet and venturi) or a deep well pump with the jet and venturi mounted on the end of the suction pipe with a 2nd pipe to provide the pressure and flow to the venturi. They come in a range of nominal flow rates (98L/min to 245Lmin) at the surface and can produce up to 1145kpa with the correct jet and venturi. When fitted with a deep well kit they can also draw up water from a depth of up to 49m. The single phase units come standard with Square D pressure switch, with the option to set up a pressure tank to make the system run properly. The 3 phase pumps come as a bare pump and need external control.

The 543/544 have composite housings and the rest have Cast iron housings, with glass reinforced polycarbonate impellor and noryl internals, a 1/2″ shaft on the JJ400 and a 3/4″ shaft on the 543/544, JJ600, OJ700 and OJ800. We stock mechanical seals, bearings, O-rings, capacitors and aftermarket pressure switches for the entire range of shallow and deep well pumps.
