Mechanical Seal BM3A
Heavy duty solutions for medium and high pressures operations.
Heavy duty solutions for medium and high pressures operations are widely used on multistage and boiler feedwater pumps.
The BM3A has a type A pinned stationary seat, pressure balanced, manufactured in accordance with UNI EN 12756 (ex DIN 24960).
Both are suitable for clockwise or anti-clockwise rotation.
With the three drive lugs on the rotating body, they can tolerate high levels of vibration, and mechanical stress.
The O-ring is easily removed and refitted when assembling the seal on shafts with keyways, threads or sharp edges.
The BM3A is a multi-spring version more suitable for clean liquids.
