Pumps of the series 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 in serial connection before the side channel stages to obtain a more favorable NPSH.
Applications:
CEH pumps pump clean liquids smoothly under adverse suction side conditions. They suit positive suction heads under 0.5 m. Due to its multiple material possibilities, homogeneous dimensions and performance, and interchangeable components, the CEH is ideal for pharmaceutical, chemical, petrochemical, plastic, and oil applications. Condensate, refrigerant, boiler feed water, and LPG can be pumped under vapor pressure with the CEH’s low NPSH and positive suction head. Retention stages prevent dry running in CEH /7 series pumps. This design handles liquids at vapor pressure or while pumping from underground tanks. The CEH /5 series bottom-offloads liquids under vapor pressure.
