Turbine Styles

  • Kaplan
  • Francis
  • Bulb
  • Reversible Pump
  • Pelton Wheel

Kaplan Units

Their applications include blade seals (trunnion seals), wicket gates, turbine shafts, brakes, and servomotors.

Turbine Shaft Seals

We offer a range of braided packings with the common styles loaded with either Teflon or graphite. Both of them are supplied with a built-in breakout lube for initial start-up. Otherwise, we offer a spring energized bearing seal.

Adjustable Kaplan Blades

Known in the industry as Kaplan blade seals or trunnion seals, these products come in different designs depending on the available seal housing depth.

  • Back-to-Back V-Pack
    This style of packing is produced completely from rubber and molded to size and height. The packing set offers double redundancy in both directions using a bidirectional center gland ring. When the packing is supplied in split form, the intermediate rings are cut at a standard 45 degrees, and the center gland ring is cut with a diamond cut to reduce leakage path. The all-rubber design is used to avoid possible shrinkage when using standard fabric and rubber rings.
  • Floating Back-to-Back V-Pack
    This floating style does not require an initial compression on the seals to operate. It also offers the double redundancy and bidirectional ring. For OEM equipment, we supply the endless seal sets. On the other hand, for in-field installations, we supply a split seal design that is joined in the field, thus making it an endless seal set. The split set rings are supplied with a diamond cut for easy and proper alignment.
  • Floating U-Cup
    This style of seal is used for applications with a shallow packing box when you can only put one seal in each direction.

Bulb Units

The three styles of blade seals (trunnion seals) used on a Kaplan unit are also used on bulb units.

Wicket Gates

Can supply floating U-cups, floating V packing in standard material or from all rubber due to low pressure.

Wicket gates are used on Kaplan, Francis, bulb, and reversible units. They are low-pressure sealing applications recommended by our professionals.

Brakes

We have supplied several seal designs and materials for this particular application.
Our team recommends using a floating V-pack, a standard V-packing, or a floating U-cup.
