Features

GMC
Safety
The double mechanical seal with oil chamber ensures safe separation separating the
motor from water and providing further protection against accidental operation when dry.
Reliability
The lower double ball bearing ensures high reliability under all operating conditions.
High security
The three-phase motors are equipped with integrated thermistors, which provide the
motor with thermal protection. The motor cable is pre-wired to enable the user to connect
directly to a control panel, providing easier installation.
Flexible installation
The availability of the pump casing with horizontal or vertical flanged ports allows the
installation of pumps in all pits and wells, both small and large sizes. Installation is also
possible with a duck foot coupling.
