Advantages:
Non-Clogging- A patent pending elastomeric pack acts as a spring and cannot be clogged.
Free From Dynamic "O" Rings- The same elastomeric pack provides a seal on the sleeve and cannot "hang-up".
Self Aligning - A patented self aligning stationary seat will invariably position itself parallel to the rotating face.
Free From Harmonic Vibration - The elastomeric pack dampens static and dynamic shocks associated with hydrualic load fluctuation even at elevated R.P.M.
Hydraulically Balanced Design - Means increased performance parameters and extended seal life.
Free From Setting Clips Or Tabs - One non-removable setting collar allows the seal to run concentric and at the right working length.
True Running - A "soft footed" rotor gyroscopically aligns perpendicular to the shaft axis.
No Leakage At The Stuffing Box Face - A patented feature enables the operator to stop most gland/stuffing box face leakage while the pump is running.
