HD COUPLING
QF COUPLING
The HD (HeviDuty®) coupling connection is engineered for high pressure ranges. They are designed for operating pressures of up to 200 bar. The weld-on collars, in conjunction with the two-shell coupling, ensure a force-fit and extremely tight connection. The end faces of the HD weld-on collars are plain - this has the advantage that individual pipes can be replaced during servicing without having to push the pipeline apart. The HD system can be connected to any high- density solids pump using appropriate adapter pipes. THE ALL-ROUNDER FOR HIGH PRESSURE RANGES IN HYDRAULIC CONVEYING
QUICK INSTALL, EASY MAINTENANCE - THE ALTERNATIVE TO FLANGES Derived from the coupling connections of hydraulic conveying, we have developed the QuickFix system (QF) for pneumatic conveying with pressures of up to 10 bar. This type of connection saves space and is extremely quick to install with just one bolt in the coupling. This system is primarily suitable for the pneumatic transportation of bulk materials. The coupling is pressure-tested with a safety factor of 2.
