EH pumps are designed in accordance with ISO 2858 standard while the performance even better than ISO 2858. Pumps have superior hydraulic design, by which significantly higher efficiencies are achieved for less power consumption. The flow rates are 1.6 times and the heard are 1.25 times of their correspondent sizes ni ISO 2858 standard.
Pump performance can be changed by impeller trimming. There are 4 sizes of shafts and 4 sizes of bearing housing among the whole series, and many of the parts such as shaft, shaft sleeve, shaft seal and impeller nut of one pump are interchangeable with other pumps of the same bearing housing.
Back pull-out design and driven by motor or other driving device through flexible coupling, very easy and convenient to install and maintain.
