Onga pressure pump range parts

The range of pressure pumps manufactured by Onga are suited to Australian conditions. There are 3 major types:

  1. The SMHP range of multistage centrifugal pumps. These pumps provide a flow rate from 20L/min to 80L/min and up to 300-350kpa operating pressure.
  2. The JM series of jet assisted single impellor pumps. These are a polypropylene housing and composite impellors and provide 15-30L.min for small household applications. These are a great economical pump.
  3. The JS range of jet assisted single impellor pumps. These pumps have a stainless steel housing and composite jet and impellors. an internal jet and venturi setup, to help the impellor with suction lift and also create output pressure. They come in a range of nominal flow rates (15L/minup to 50L/min) and produce approximately 200kpa at their nominal flow rate. The come as a bare pump, with a pressure switch and tank and also with a press control unit.

We stock mechanical seals, bearings, O-rings, capacitors and aftermarket pressure controllers for all the Onga pressure pump models.
