Applications
The 2-pole A series is designed 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 dewatering.
Specifications
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 feature an open, single-channel impeller with excellent performance for pumping raw sewage and cutting fibrous materials. On the one hand, the single channel limits flow separation in the pump’s hydraulic system, preventing fibrous matter from wrapping around the impeller. On the other hand, long materials are cut by the cutting pair formed by the impeller and the pump housing plate. At the same time, the impeller is significantly more efficient than those in pumps with free passage and Vortex-type impellers.
A2 Pump Installation
Wecause 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.
