Sterling - Shaft seal type WPR
The
WPR Seal is suitable for all types of turbines including reversible pump
turbines and as face loading is remotely controlled by water pressure it is
particularly suited to turbines where there is no access to the seal for
adjustment. All Seals are custom designed and are tully split for ease of
installation and maintenance. The main wearing face is made from a special
composite material that will regenerate mutually conforming seal faces if
damaged by abrasive particles.
Benefits
- Positive Sealing -
Hydraulically balanced faces
dimensioned to suit the application give minimum leakage.
- Long Life -
Seal
life is built in and this combined with a wear indicator
facilitates planned maintenance. Seal face life in excess
of ten years is not uncommon.

|
- Non Clogging -
Smooth
contours and no springs in the water prevent clogging in
silty conditions.
- Durable Materials-
All
wetted components are manufactured from corrosion
resistant materials.
|
- Robust -
The composite wear face can be dropped without
damage unlike carbon. It can also withstand vibration and abrasives
without permanent damage.
- Space Saving -
Custom designed seals can usually be engineered
to fit into the available space.
|
|
- Easy Maintenance -
Simple robust components are easier to handle
and fit than multi-segment carbon glands thereby reducing downtime and
maintenance costs.
- Flexible Design -
Can accommodate axial and radial shaft
movements without special precautions.
