CONSTRUCTION FEATURES

Dry Motor

Sealing System

The silicon carbide mechanical seal, highly resistant to abrasion and wear, and the lip seal, continuously lubricated thanks to the special design of the oil chamber, ensure the absolute tightness of the motor seal.
In the event of dry running, the sealing system will not be damaged and the motor will not suffer from infiltration.
The oil used complies with FDA (FOOD AND DRUG ADMINISTRATION) standards.

Single-phase models with float (CG) are also available
