The DSR pumps series comply fully to the European standard DIN24255. This standard cover both performance and dimension. The DSR pumps series are use for pumping clean water or liquids with characteristics similar to water.
For a pump of same 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 pump fitted to the same shaft. Just like the shaft, bearing house has only four sizes 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.
