ΣΤΥΠΙΟΘΛΙΠΤΕΣ – Σειρά BS3A-BM3A

Heavy duty solutions for medium and high pressures operations are widely used on multistage and boiler feedwater pumps.
The BS3A and the BM3A are single component seals.
For both of these, type A has 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.
Because of 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 BS3A version is supplied with a single spring and is more suitable for moderately dirty liquids.
The BM3A is a multi-spring version more suitable for clean liquids.
