Pearl End Suction Centrifugal Water Pump - CEC Series Pumps

SINGLE IMPELLER

The compact design allows for easy installation even in confined spaces. The mechanical structure of the hydraulic parts in contact with the pumped liquid are dimensioned to guarantee the maximum resistance to mechanical stress.
The lantern bracket design prevents contact with the pumps rotating parts, providing protection to the end user whilst allowing for inspection of the mechanical seal.
The bearing and shaft are designed to ensure the reduction of the stress, providing high reliability under all operating conditions.
