Submersible pump Dreno AT-EX 80/2/173 C.257 with single channel open impeller

Pump application: the A2 pole series is used for pumping and draining clear liquids and wastewater. Its high productivity makes it useful in a variety of applications: sewage treatment plants, industrial enterprises, farms and sewers. Feature: all main components are made of GG25 cast iron. Two separate mechanical seals (the engine side in the oil chamber, the impeller side in contact with the liquid) and high-quality parts ensure perfect operation and reliability of the product. Motor range: 2-pole short-circuited rotor motor; thermal protection T1 and T2 integrated in the motor winding (connected to a three-pole Contactor on the control panel); Class F insulation (155°C); protection class IP68. Engine cooling: engine cooling is provided by the liquid in which the pump is immersed.
