Solosele® KB Hydro special duty seal

Special duty products Solosele® KB Hydro

For Kaplan turbine blade roots

Description
Solosele® KB Hydro is an innovative
product developed specifically to
seal the blade roots of Kaplan water
turbines.

This profiled elastomeric seal is reinforced
at the base with an integral anti-extrusion
element of rubber-proofed fabric that is
securely mould-bonded to the lip portion.
The anti-extrusion element is sufficiently
tough to stop the seal from ‘stretching
and bunching’ when the shaft rotates, yet
is remarkably flexible for ease of fitting.

Tube test seals

Special duty products Tube test seals

High-pressure hydrostatic testing

We manufacture two types of seal
that are specifically designed to
operate with tube testing machines
that repeatedly seal and release the
tube ends as part of the hydrostatic
testing process.

The quality of such seals is a crucial
factor in the reliability of the machines’
operation; our tube test seals therefore
provide the highest levels of performance.

Other designs are available on request.

'O' rings

'O' rings ‘O’ rings

Highly versatile sealing devices

Description
The seemingly humble ‘O ring, or
toroidal seal, is a highly versatile
device that is rated as the world’s most
popular volume produced fluid seal.

James Walker has been manufacturing
top quality ‘O’ rings since this sealing
method was introduced in the 1930s.
Today we stock thousands of types and
sizes of ‘O’ rings ready for same-day

WARNING: Please note that, due to the complexity of making a material selection for any given duty, all information provided in this document
on chemical compatibility is intended only as a guide. For example, a compound compatible at low temperatures may show considerable deterioration
at high temperatures; also, combinations of chemicals in a fluid medium may have detrimental effects. Actual service life will depend on type of
application, whether static or dynamic, specific pressure medium, temperature cycle, time of exposure, etc. The low temperatures quoted are generally
values at atmospheric pressure and may change at elevated pressures. If any doubt exists, please seek advice from James Walker.

Diametral Clearance: In piston applications this is the difference between the Cylinder bore Ø - D and Piston Ø - P and it controls the level of the extrusion
gap (see Housing arrangement). It may be further increased by the expansion of the cylinder from internal pressure. The level of the extrusion gap is critical
in achieving satisfactory and long term sealing performance; it should be the subject of consultations between the housing designer and James Walker.
