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.
Features
All major components are made of GG25 cast iron. Two separate mechanical seals (the motor-side seal in the oil chamber and the impeller-side seal in contact with the liquid), together with high-quality components, ensure excellent performance and product reliability.
Advantages of A2 pumps
A2 series pumps feature a closed single-channel impeller with excellent raw sewage pumping properties. Since there is only one channel, the flow is not divided within the pump’s hydraulic system, preventing fibrous materials from winding around the impeller. At the same time, the impeller efficiency is considerably higher than that of pumps with free passage and Vortex-type impellers.
Installation of A2 pumps
As A2 series pumps are intended for professional applications, they are usually installed on DRENO guide rails 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 protection against pump damage, 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 expected pumping station parameters.
Features
- Closed single-channel impeller with a 40 mm free passage,
- Side pump outlet ending in a DN65 PN10 flange,
- 10 m power cable with free terminals,
- T1-T2 thermal protection built into the motor winding and connected to an external control panel,
- Warranty and post-warranty service,
- 24-month warranty.
