Features
- Aftermarket Industry Standard
- Equal to: John Crane Type 2100 & 2106
- A compact unitized single spring elastomeric bellows shaft seal.
- Innovative full convolution bellows and interlocking drive band design allow for positive drive and greater tolerance to misalignment.
- Interference fit of the primary ring ensures positive drive while avoiding high face distortions associated with crimped designs.
- Floating Mating ring
The seals are designed to give long life, provide automatic self-adjustment, and reduce maintenance costs. Additionally, mechanical seals offer these important advantages.
Absolute Sealing
Proper selection and installation of seals result in less pumpage loss, cleaner facilities, less fire hazard, no danger from fumes, and no contamination of the fluid being pumped.
No Rubbing Friction Between the Shaft and Seal Parts
Replace packing with a mechanical seal and avoid expensive shaft or sleeve replacements.
Flexible Seals Means Longer Service Life
Compared to packing, mechanical seals are more flexible and are able to compensate for shaft deflection, axial and radial end play, vibration, and seal face wear.
Less Friction Means Valuable Power Savings
Mechanical seals use less friction than packing. Therefore, they require less horsepower consumption.
Precision Lapped Sealing Surfaces
Positively control leakage and eliminate "break-in" runs.
Higher Speeds and Pressures
The seals are designed for higher speeds and pressures.
Flat Surfaces of Mating Faces
Sealing surfaces are precision lapped to a flatness of one to three light bands, which maintains the necessary face film lubrication, resulting in positive leakage control.
