As a close-coupled variant of the EA series, the EIFEL EAZ series dispenses with coupling components. The motor shaft is directly inserted into the pump shaft, which not only ensures precise concentricity but also reduces the overall axial dimension. Featuring highly interchangeable components and a space-efficient structure, this series is applicable to a broad range of scenarios, including industrial plants, mining operations, municipal water supply, fire-fighting facilities, air-conditioning systems and agricultural irrigation.

Field Chart
EIFEL EAZ series are Close-coupled type of EA series. No need to use couplings and motor shaft is plugged into pump shaft to ensure concentricity and shorten the axial length.
Read More
This is a close-coupled pump. It requires no separate coupling, as the motor shaft directly connects to the pump shaft. This design guarantees perfect concentricity and reduces overall axial length.
Read More
This pump adopts a close-coupled structure where the motor shaft connects directly to the pump shaft, eliminating the need for a separate coupling. This design delivers exceptional concentricity and a shorter overall axial length for easier installation.
