Applications
The 4-pole A series is designed for pumping clear liquids and wastewater. Its wide range and high hydraulic efficiency make this series particularly suitable for water treatment plants, sewage systems, agriculture, and industrial facilities, including airports, underground public transport systems, hospitals, and hotels.
Features
All major 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.
A4 submersible pumps
The A4 series submersible pumps are equipped with an open single-channel impeller, i.e. an impeller with excellent raw sewage pumping properties and a function for cutting fibrous materials. On the one hand, there is only one channel, which limits the division of the flow in the pump's hydraulic system, preventing fibrous materials from winding around the impeller. On the other hand, longer materials are cut by the cutting pair consisting of the impeller and the pump housing plate. At the same time, the impeller efficiency is significantly higher than that of pumps with a free passage and a Vortex-type impeller.
Installation of the A4 submersible pump
As A4 series pumps are intended for professional applications, they are usually installed on DRENO coupling feet of type A, B, or DUTY in municipal and industrial pumping stations. For their control, we offer customers advanced control systems with suitable motor protection and pump damage protection, such as two independent humidity probes in the motor and oil chambers, e.g. CR3.1.
We recommend consulting our specialists when selecting a submersible pump equipped with an open single-channel impeller in order to confirm the expected parameters of the pumping station.
Features
- Open single-channel impeller with a 75 mm passage,
- Side pump outlet fitted with a DN80 PN16 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.
