JJ and OJ Dual Pump Sets
JJ and OJ dual pump sets consist of two identical pumps. The pumps alternate at start up which reduces the load on any one pump, and extends the life of the product. Duty assist stand-by operation, if water demand is greater than one pumps performance the second pump starts, effectively doubling the water available.

Used in conjunction with a suitable onga pressure tank to minimise pump cycling.


Features
  • Two pumps alternate to share the load.
  • Manual mode or automatic mode.
  • Pump isolation switch.
  • Operating warning lights.
  • Failure warning lights and reset buttons.
  • Low voltage safety shut down.
  • Additional control circuit for control box, loss of prime, float switch or other protection device.
  • Overload protection.
  • Run-on timer to minimise cycling.
  • Quick cycling indicator as a warning to check the air charge in the pressure tank.
  • One pump automation operation if the second pump fails.
  • Dual pump operation on demand.
  • Over temperature protection option.
Applications
  • Ideal for providing large volumes of water on demand.
  • Suitable for many commercial applications where a back-up pump is necessary.
  • Energy saving design as second pump only works when required.
