BT-ARP mechanical seals are the ideal solution for media 

which contain solids or are highly viscous. The spring is 

product-protected, thus preventing sticking or clogging. 

Reliable for rugged operation in all kind of applications 

such as waste water treatment. The dimensions can be 

adapted and additional seats are available. The bellows 

provides protection across the entire seal length.
