We offer a high-quality Protected spring mechanical seal, the BV-2 model. This seal is engineered with a special design where the spring is out of contact with the product, making it ideally suited for pumping high viscosity and abrasive media without clogging.

To meet strict hygiene standards, the seal features electropolished metal parts and formed secondary sealings that avoid gaps, ensuring suitability for sterile applications.

It is a balanced seal, designed to operate independently of the direction of rotation, and fits perfectly into dimensions according to DIN 24960 (EN12756).

• Resin impregnated caron(В)
• Antimony impregnated carbon (A)
• special CrMo steel(Е)
