Jenny J4 Design

The J4 is very compact in design where the minimum length is reduced to lower the center of gravity for greater stability. This unit is small and light enough to be moved around, to be of survice as a portable pump. This pump has a full water jacket where water flows around the entire motor housing which ensures good cooling even if the pump is not totally under water.

Wet end of the pump consists of a single centrifugal impeller with a cast metal diffuser, creating a relatively moderate head and flow performance for the amount of power available.

These applications would typically be:

  • Mining applications (including fiery mines),
  • Industrial waste water,
  • Agriculture irrigation,
  • Construction site drainage,
  • Commercial and domestic water features.

Careful consideration has been taken when designing this unit to minimise onsite maintenance by utilising sealed for life bearings and a double sided mechanical seal running in an oil bath. Onsite maintenance is not recommended but rather a standby unit as a backup.

Jenny J4 Application

The unit can be mounted on an Amandla Float when required.

J4X - Jenny  is Ex d I approved according to SANS 60079-1 for underground use in fiery mines. All international 3-phase standard voltage ratings are available from 380 to 1000V.

Material construction ranges from basic complete cast iron to chrome iron and stainless steel constructions or a combination thereof. Other special materials of construction are available on request.
