Wps 330 3rd is a tumbling barrel for water polishing buttons, beads and costume jewellery in polyester, acrylic and acetate materials. It can also be used with great advantage during roughing operations for urea and galalith buttons.The steel barrel is lined internally with a material which is highly resistant to abrasion. The water inlet, placed on the rear part, allows considerable saving on water consumption. The barrel is rotated by a two-speed motor and reduction gear which prevents jerks when starting and stopping, thus extending the life of transmission. The up-and-down movement of the barrel is driven by a motor gear (no maintenance required). The electric wiring is in conformity with EC rules with a waterproofing grade IP65.
