Sterling - Shaft seal type HHSS

horizontal rule

HHSS Type seals are suitable for all types of turbines including reversible pump turbines as long as there is access for adjustment of the spring loading during and after commissioning. All seals are custom designed and are fully 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.
