Compact DesignThe compact design allows for easy installtion even in confined spaces.

RobustnessThe mechanical structure of the hydraulic parts in contact with the pumped liquidare dimensioned to guarantee the maximum resistence to mechanical stress.

A unique designThe lantern bracket design prevents contact with the pumps rotating parts, provi-ding protection to the end user whilst allowing for inspection of the mechanical seal.

ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providinghigh reliability under all operating conditions.
