FEATURES
|
APPLICATIONS
|
|
1. Enclosed high chrome cast iron impeller with field adjustable/replaceable wear plate provides for high wear resistance when the pumpage contains abrasive particles.
|
1. Commercial, industrial wastewater and site drainage.
|
|
2. Highly efficient, continuous duty air filled, copper wound motor with class F or E insulation minimizes the cost of operation. The motor is equipped with a water cooling jacket
allowing for low water level operation for extended periods of time.
|
2. Sand and Gravel pit drainage.
|
|
3. Built in thermal protection prevents motor failure due to overloading, accidental run-dry and single phasing in three phase units.
|
3. Fly Ash water return.
|
|
4. Double inside mechanical seals with silicon carbide faces, (both top and bottom) running in an oil filled chamber, further protected by a labyrinth seal, running against a replaceable,
420 stainless steel shaft sleeve and seal pressure relief ports, providing for most durable seal design available.
|
4. Raw water supply from lakes or rivers.
|
|
5. Double shielded, permanently lubricated, high temperature C3 ball bearings rated for a B-10 life of 60,000 hours provide for extended operation life.
