Jenny J90M Dewatering Drainage Pump
Jenny J90M – Standard construction
Jenny J90MX – Flameproof construction
The Jenny J90M 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.
This pump can be run vertically or horizontally. When the pump runs vertically the motor is below the wet end and remains submerged even when the water level drops low enough for the unit to lose prime and stop pumping, thus keeping the motor cool. When the unit is run horizontally the motor will be partially submerged when the water level drops low enough for the pump to lose prime, still giving partial cooling to the motor.
The wet end consists of a single double sided centrifugal impeller and a volute casing with two polyurethane lined suction covers creating a lower head compared to the J90H but with significantly higher flow. The impeller is a double sided open vane impeller with adjustable suction covers to allow for adjustment when the impeller is worn.
Careful consideration has been taken when designing this unit to minimise onsite maintenance by utilising a greased roller bearing and two greased angular contact bearings and two independent mechanical seals running in an oil bath. Onsite maintenance is not recommended but rather a standby unit as a backup.
The unit can be mounted on an Amandla Float when required.
The Jenny J90MX 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 1000 V.
Material construction ranges from basic cast iron with a high chrome iron impeller and polyurethane linings to full stainless steel construction or a combination thereof. Other special materials of construction are available on request.
Flameproof units are identified by an additional suffix X after the pump model name.
