FEATURES
|
APPLICATIONS
|
|
1. Semi-open, Ductile Iron impeller with replaceable/adjustable wearplate increases wear resistance when pumpage contains abrasive particles.
|
1. Commercial, industrial dewatering and construction site drainage.
|
|
2. Double inside mechanical seals with silicon carbide faces, (both top and bottom) running in an oil filled chamber and further protected by a lip seal running against a replaceable, 420
stainless steel shaft sleeve, provides for the most durable seal design available.
|
2. Effluent transfer
|
|
3. Highly efficient, continuous duty air filled, copper wound motor with class E, B and F insulation, minimizes the cost of operation.
|
3. Decorative waterfalls and fountains
|
|
4. Built in thermal and amperage sensing, protector prevents motor failure due to overloading or accidental run - dry conditions.
|
4. Raw water supply from rivers or lakes
|
|
5. Double shielded, permanently lubricated, high temperature C3 ball bearings fated for a B-10 life of 60,000 hours, extend operational life.
|
|
|
6. Top discharge, flow-thru design enables operation at low water levels for extended periods.
