SIHI® CEH Side-Channel Pump

Pumps of the series CEH-X/CEH have a segmental type construction with open vane wheel impellers. The construction of the CEH pump is a so-called centrifugal combined system. This combination pump is suited with a centrifugal stage serial connection before the side channel stages in order to obtain a more favorable NPSH.

Frequently asked questions

What is the SIHI CEH side-channel pump used for?
The SIHI CEH is an industrial side-channel pump for clean liquids where suction conditions are challenging. Typical applications include condensate, refrigerants, boiler feed water, LPG and liquids near their vapour pressure.
What is low NPSH and why does it matter?
NPSH relates to the pressure available at the pump inlet. The CEH’s low-NPSH design helps reduce cavitation risk where suction conditions are limited or the liquid is close to boiling.
How many sizes and stages are available?
The CEH range includes six pump sizes with up to eight stages, allowing it to be matched to different flow and head requirements.
How do I choose the right SIHI CEH pump?
Selection depends on the liquid, vapour pressure, required flow and head, suction conditions, temperature, materials and seal arrangement. Contact us and we can help identify a suitable configuration.
