Jenny J11M Dewatering Drainage Pump
The Jenny J11M is a new pump model in our de-watering vertical submersible pump range, it slots in perfectly between the new design J4 and J22. The design of this pump allows for clean and dirty water applications where small particles may be present.
Jenny J11M – Standard construction
Jenny J11MX – Flameproof construction
The Jenny J11M is designed for typical drainage and dewatering applications where small particles may be present but limited to a maximum SG of 1.05. These applications would typically be:
- Mining applications (including fiery mines),
- Industrial waste water,
- Agriculture irrigation,
- Construction site drainage,
- Commercial and domestic water features.
The J11M is very compact in design where the length has been minimised to lower the center of gravity for added stability. 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 submerged.
The wet end consists of a single centrifugal impeller with a polyurethane lined diffuser and suction cover creating a lower head compared to the J11H but with significantly higher flow. The impeller is an open vane impeller with an adjustable suction cover to allow for adjustment when the impeller is worn.
Careful consideration has been taken when designing this unit to minimise onsite maintenance by utilising sealed for life bearings and two independent mechanical seals running in an oil bath. Onsite maintenance is not recommended, apart from impeller adjustment or clearing the wet end of debris, but rather a standby unit as a backup.
The unit can be mounted on an Amandla Float when required.
The Jenny J11MX 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 cast iron with duplex stainless steel impeller and polyurethane linings to full stainless steel construction or a combination thereof. Other special materials of construction are available on request.
