Explosion-proof pumps
The 2-pole A series is designed for pumping clear liquids and raw sewage. The high-performance open single-channel impeller makes this type ideal for wastewater treatment plants, industrial sewage systems, agriculture, and drainage applications.
The pumps can be used in all hazardous areas in accordance with CE0477 EPT 17 ATEX 2701 X certification, Ex II 2G [Ex db IIB T4 Gb, Ex h IIB T4 Gb, 0°≤Ta≤40°, available on request.
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), together with high-quality components, ensure excellent performance and product reliability.
Advantages of A2 pumps
A2 series pumps are equipped with a closed single-channel impeller with excellent raw sewage pumping properties. There is only one channel, which limits flow separation in the pump's hydraulic system, preventing fibrous materials from winding around the impeller. At the same time, the impeller efficiency is significantly higher than that of pumps with free passage and a Vortex-type impeller.
Installation of A2 pumps
As A2 series pumps are intended for professional applications, they are usually installed 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 safeguards against pump damage, such as two independent humidity 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 expected pumping-station parameters.
