DRIVELUB SEAL SYSTEM

Watertight electric motor protected by multiple seal system with oil chamber. A V-ring and silicon carbide mechanical seal mechanical seal (extremely resistant to wear and abrasion), as well as a lip seal lip seal which is continuosly lubricated by the DRIVELUB system, provide an extreme barrier against infiltration.
