Summary:

AE/SE/SEH is a new generation of single-stage single suction centrifugal pump, which is a new generation product after optimizing the hydraulic model and structure on the IS standard pump. Compared with IS series single-stage single suction pump, AE/SE/SEH new generation end suction pump has the following advantages and characteristics:

1. The hydraulic performance of the pump is better. Under the same flow head parameters, the inlet and outlet diameters of some pumps are less than those of IS series pumps, and the efficiency is much higher than that of IS series pumps.

2. New design and manufacturing standards are adopted. AE/SE/SEH new generation end suction pump is in line with international standards, and the design and manufacturing standards adopted comply with ISO5199, ISO2858, GB/T 5656 and GB/T 5657 standards.
