Description:
The EA pumps series comply fully to the European
standard DIN24255. This standard covers both
performance and dimensions.
The EA pumps series are used for pumping cleanwater or liquids with characteristics similar to water. They are suitable for plants, mines , city water supp lies , air-conditioning coolers , firefighting system and irrigation.
For a pump of same the model, the performance can be changed by trimming the outer diameter of the impeller. Only four shafts are required to cover the total range, and this gives many common interchangeable parts for pumps fitted to the same shaft. Just like the shaft, the bearing house has only four sizes for the whole series.
The pump has a back pull-out design, and when a suitable spacer coupling is fitted to a direct coupled unit, the casing and motor can remain in position while
all other pump parts can be removed for simple and quick maintenance.
