Grout/Concrete Swivel and Shock Absorber

Grout/Concrete Swivel

Our swivel is especially designed for use with down-hole-hammers having operating pressures of up to 25 bar and are therefore also suited for use with modern high-pressure Down-Hole-Hammers.

High-quality seals are used for long lifeand a generously dimensioned shaft allows for high flushing speeds and large volumes.

The swivel can be equipped with couplings to suite customer requirements.

A bracket to arrest the swivel and prevent rotation of flushing/grouting hoses together with a cleaning hole is included as standard.

The swivel is also available with a double walled for reverse circulation drilling systems.

Shock Absorbers

Our shock absorbers are designed to offer maximum protection to rotary heads from vibration travelling up the drill string when using large diameter or high-pressure down-hole-hammers.

The shock absorber is mounted directly between the rotary head or down hole hammer and first drill rod.

Vibrations are absorbed by damping disks inside the shock absorber.

The shock absorber is also available with double wall for reverse circulation drilling systems.
