Applications
The 4-pole A series is designed for pumping clear liquids and wastewater. Its wide range and high hydraulic efficiency make it particularly suitable for water treatment plants, sewer systems, agriculture, and industrial facilities, including airports, underground public transport, hospitals, and hotels.
The pumps can be used in all potentially explosive atmospheres in accordance with certificate CE0477 EPT 17 ATEX 2701 X, Ex II 2G [Ex db IIB T4 Gb, Ex h IIB T4 Gb, 0°≤Ta≤40°. Available on request.
Specifications
All major components are made of GG25 cast iron. Two separate mechanical seals (on the motor side in the oil chamber and on the impeller side in contact with the liquid), along with high-quality components, ensure excellent performance and product reliability.
A4 Submersible Pumps
The A4 series submersible pumps feature an open, single-channel impeller, which offers excellent performance when pumping raw wastewater and cuts fibrous materials. On one hand, having just one channel limits flow separation in the pump's hydraulic system, preventing fibrous materials 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 much more efficient than those used in pumps with free passage and Vortex-type impellers.
A4 Submersible Pump Installation
WSince A4 series pumps are intended for professional use, in most cases they are installed on DRENO coupling feet of the following types: A, B or DUTY in municipal and industrial pumping stations. We offer customers advanced control systems for operating them, with appropriate motor protection and safeguards 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 a submersible pump with an open single-channel impeller to confirm the required pumping station parameters.
Features
- Open single-channel impeller with a 75 mm passage,
- Side pump outlet with a DN80 PN16 flange,
- 10 m power cable with a starter box,
- T1-T2 thermal protection built into the motor winding, connected to an external control panel,
- Warranty and post-warranty service,
- 24-month warranty.
