AT 80/2/173 C.257 (7,5 kW, 400 V) submersible pump

Applications

The 2-pole A series is used for pumping clear liquids and raw sewage. Its high-performance open single-channel impeller makes this type of pump ideal for wastewater treatment plants, industrial sewage systems, agriculture, and drainage.

Characteristics

All main components are made of GG25 cast iron. Two separate mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid) and high-quality components ensure excellent performance and product reliability.

Advantages of A2 pumps

A2 series pumps have an open single-channel impeller, i.e. an impeller with excellent properties for pumping raw sewage and cutting fibrous materials. On the one hand, there is only one channel, which limits flow separation in the pump's hydraulic system, preventing fibrous matter from winding around the impeller. On the other hand, long elements are cut by the cutting pair: the impeller and the pump housing plate. At the same time, the impeller is much more efficient than those in pumps with free passage and a Vortex-type impeller.

A2 pump installation

WSince A2 series pumps are designed for professional applications, they are installed in most cases on DRENO coupling feet of the following types: A, B or DUTY in municipal and industrial pumping stations. For their control, we offer customers advanced control systems with appropriate motor protection and pump damage protection, such as two independent moisture probes in the motor and oil chambers, e.g. CR3.1.

We recommend consulting our specialists when selecting pumps with an open single-channel impeller to confirm the required pumping station parameters.
