Unbalanced PTFE Wedge Seal Johncrane 59U Replacement
Product Description
+
This component is PTFE wedge-mounted, designed with multi-springs. It can rotate in both directions, and the drive of the shaft is fastened using set screws tightened with the hex key. The multi-springs and robust design provide even closing forces around the sealing face circumference, which lead to improved pV capability and higher sealing performance.
The narrow-designed radial profile is suitable for European DIN24960/En12756 metric seal chamber.
It is suited for pump or devices such as the Mitsubishi CVD-25L, Viking LVP19, Viking LVP23 and others.
