Peripheral Drive Clarifier

Hubert clarifiers come standard with a two-wheeled carrier. One wheel is directly driven by a motor reduction gear. In the centre of the tank, the bridge is supported by a ball thurst bearing.

Various types of bridge beams can be provided:

Tubular beam
Plate beam
Profile beam
Triangular beam (aluminium)
Trapezium beam (aluminium)

These beams can be supplied as follows:

Half bridge: the peripheral side of the bridge is fitted with a two- wheeled carrier
Two/third bridge: the peripheral side of the bridge is fitted with a two-wheeled carrier
Full bridge: the bridge is fitted with a two wheeled carrier at either end

Central Drive Clarifier

For tanks with a diameter up to 50 m, a central drive or cage drive can be used. The drive features a special drive unit fitted to the shaft or cage which can be equipped with an overload sensor. The scraper arms are fitted with blades and are connected to the drive unit by means of a shaft or cage.

See also our seperate product page Central Drive System.

Benefits

Unlike other designs, our scraper system does not rest on wheels over the tank bottom. There is no contact with the bottom (with the exception of the rubber strip), wear to the bottom of the tank is not an issue and risks of malfunction during operation are minimized.
