General Description
(continued)
The machine with Electrical gear motor (at frequency 50 Hz) is rotating at fixed speed: 14 RPM with
2xø2mm nozzles and 6.5 RPM with 4xø4.2mm nozzles. The machine with 2xø3.8mm nozzles is
available in both a High Speed (14 RPM) and a Low Speed version (6.5 RPM).
Self-cleaning
Apart from the main flow flushing the inside of the Base housing and the Down pipe, and thereafter
forming the jets through the Nozzles, fluid is flushed through all internal cavities, through Bevel gear,
Ball bearings and gabs between moving parts and is finally also used for cleaning of the outside
surfaces of the machine.
From the gab between the Base housing and the rotating Down pipe, a cleaning jet is directed against
the Down pipe, thus loosening and removing product remains on the outside. A liquid film flushing all
around the tube further assists by continuously transporting away loosened product remains. The front
of the Cleaner head is flushed by a liquid flow from the gab between the Cleaner head and the
Retaining ring.
In order to ensure a proper self-cleaning, the machine must be installed in an approx. upright position
and the inlet pressure must be min. 3 bar.
In the bottom of the Cleaner head, in the Retaining ring, the machine is equipped with a hole to ensure
self-draining. This self-draining is only ensured, if the machine is installed in an upright position.
