Available in different versions, these suction rings are technically sophisticated hybrid modules comprising a housing made from a circular stainless steel blank with multiple perforations precisely punched and machined, a rubber band with a perforation running around the outer surface, and a plastic channel and jet system pressed inwards.
All components are sealed airtight, securely riveted to one another and are supplied as a single unit ready for installation. The complete part has a diameter of 100mm and a height of 20mm. Unlike solid suction rings, the new hybrid modules are considerably lighter and less expensive.
