Coupling for Conveying of Fragile Materials

January 14, 2014

Schenck Process Quick Clamp No-Ledge CouplingSchenck Process LLC, a North American design/build provider of pneumatic conveying, air filtration, weighing and feeding systems and manufacturer of Mac Process and Schenck AccuRate equipment, has launched the new Quick Clamp No-Ledge coupling. Part of the Clean Design Initiative, the Quick Clamp No-Ledge coupling is designed for food and light industry conveying of fragile materials or materials requiring a high degree of sanitation. Unlike a compression coupling, which can have frequent pipe misalignment during installation, the Mac Process Quick Clamp No-Ledge coupling delivers a machined tolerance joint. This ensures proper alignment and creates a ledge-free interior environment on connection points. As a result, friction and crevices which catch product and cause fines are greatly reduced. The Quick Clamp No-Ledge coupling offers a recessed O-ring gasket that delivers a smooth transition through a positive sealing metal-to-metal joint. This eliminates gasket contact with the product stream — a critical improvement in sanitary piping system design. Quick Clamp No-Ledge is available with a single T-handle or nut, or backing flanges that tightens the clamp around the male and female flanges. The clamp presses the face of the male and flanges together by way of a bevel on the edge of each flange compressing the o-ring creating an air tight seal. Lightweight design and a tool-free assembly option speeds installation.
