Conical spring mechanical seal AS-R12 to replace vulcan type 12,Burgmann BT-RN.
Features：
The seal contains the secondary seal——the o ring. The face materials and elastomers can be varied as per requirement of the application. The conical helical springs transmits the torque. The seals depend on the direction of the rotation. The conical helical spring can be fitted easily by pushing on the shaft and twisting as the spring winding. So, the spring diameter enlarges easily to make easy fitting. One can judge the direction of the rotation from the drive end of the shaft.
The clockwise rotating shaft requires the right handed spring and anti-clockwise rotating shaft requires left handed spring.
Recommended applications：
The conical single spring unbalance seals are used in central heating system in circulation pumps. It’s also used in the chemical process pumps, sewage and submersible pumps and chemical process pumps.
