Shaft Grounded Pump Motors

The need for proper motor grounding is extremely important in preventing premature bearing failure which could result in high maintenance costs or worse - facility downtime. The Baldor-Reliance close-coupled pump with internal AEGIS® bearing protection ring is the ultimate pump motor that can be paired with a VFD. The shaft grounding ring is installed internally in a protected environment shielded from contaminants that could affect its performance.
