WAM Minimum Residue Tubular Screw Feeders – EASYCLEAN

EASYCLEAN are specialised Screw Conveyors and Feeders entirely manufactured from stainless steel.

WAM Minimum Residue Tubular Screw Feeders - EASYCLEAN

They consist of a tubular housing equipped with at least one inlet and outlet spout, one end plate at the drive end to carry end bearing assembly and drive unit, a tube cover plate complete with screw fixing locator for support of the screw at the end opposite the drive unit, a rotating screw with a shaft coupling bush at each end, a gear motor with integrated end bearing assembly complete with adjustable shaft seal in accordance with the requirements of the application.

To satisfy the needs of the most demanding industrial sectors, EASYCLEAN Screw Conveyors and Feeders come with a high finishing grade. Finishing of fabricated components takes place on machine tools that guarantee a perfectly smooth internal surface in order to reduce material residue inside the screw conveyor.


The particular design features and total absence of nuts and bolts inside the EASYCLEAN Screw Conveyor / Feeder allow quick and efficient cleaning of all the conveyor parts, as well as minimum material residue inside. To a great extent this is due to minimum clearance between flight and outside tube which is obtained from a slightly eccentric position of the screw axis towards the bottom of the tube. The maximum clearance between flight and trough is less than 5 mm (0.2 in).

Furthermore, the end play of the screw between screw and end plate amounts to 2.5 mm (0.1 in). All inspection hatches are supplied complete with a locking device that requires the use of a tool for unlocking and opening, as required by the Directive 98/37/EEC and subsequent amendments. EASYCLEAN are suitable as conveyor or feeder for powdery or granular materials in applications in which quick access to the internal parts of the screw conveyor (e.g. for frequent cleaning) is essential.

EASYCLEAN Screw Conveyors and Feeders are particularly used in the food industry, in plastics and chemicals processing, and within certain limits, in the pharmaceutical industry.
