3-5 Flange Mounting Tips
; Run a bead of silicone sealant around the mounting flange before seating the vacuum hopper.
This makes a better seal.
; Use rivets to mount the hopper. Nuts and bolts can loosen, fall off, and damage process
equipment.
; Check across the mounting flange with a bubble level. A level installation is important for
proper hopper dump.
; Properly ground all sight glass loaders and vacuum hoppers.
3-6 Installing Material/Vacuum Tubing
Note: System capacity is directly affected by the pressure drop in the overall system, such as
number of material line bends, footage of pipe, Y-tubes, T-tubes, etc.
Use the minimum effective amount of vinyl flex hose to maximize material line efficiency. Keep
material lines as straight as possible.
Important!
Vacuum leaks anywhere in your system reduce capacity.
