High Volume Dewatering Pump
Pumps must have a solid construction, operate safely and easily, yet be compact and lightweight. Now, you'll have to top each of these attributes.
| Features |
Application |
| 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 & 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.
