Applications
The A 2-pole series is designed for pumping clear liquids and raw wastewater. The high-performance open single-channel impeller makes this type ideal for wastewater treatment plants, industrial sewage systems, agriculture, and drainage applications.
Characteristics
All main components are made of GG25 cast iron. Two separate mechanical seals (the motor side in the oil chamber and the impeller side in contact with the liquid), along with high-quality components, ensure excellent performance and product reliability.
Advantages of A2 pumps
A2 series pumps feature an open single-channel impeller, i.e. an impeller with excellent raw wastewater pumping properties and a function for cutting fibrous materials. On the one hand, there is only one channel, which limits flow division 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 consisting of the impeller and the pump housing plate. At the same time, the impeller's efficiency is considerably higher than that of pumps with a free passage and a Vortex-type impeller.
Installation of A2 pumps
As A2 series pumps are intended for professional applications, they are most often installed on DRENO-type coupling feet: A, B or DUTY in municipal and industrial pumping stations. For their control, we offer customers advanced control systems with appropriate motor protection and safeguards against pump damage, such as two independent moisture probes in the motor and oil chambers, for example CR3.1.
We recommend consulting our specialists when selecting pumps with an open single-channel impeller in order to confirm the expected pumping station parameters.
