Hopper to Transfer Car Inflatable Seals
Install Pneuma-Seal inflatable seals on the mouth of a hopper valve or metering device; they are designed to expand axially down to form a leak-tight seal around the fill opening in a transfer cart. Type 1 seals are best suited for this quick connect/disconnect application.
Inflatable Seals for Viscous Pumping Equipment
Type 10 style profiles are the ideal solution for sealing around the periphery of follower plates when pumping viscous liquids, such as grease, paste, or cake frosting from their container drums. The rectangular profile of these seals minimizes the tendency of roll out from the seal's retainer, which can pinch the seal when the follower plate descends.
Drum Filling Inflatable Seals
Type 1 and Type 2 style inflatable seals work particularly well for drum filling applications where the seal on the cover expands radially outward against the inside of the drum to allow for leak-tight filling.
Bulk Bag Filler Inflatable Seals
A filling equipment seal on the spout expands radially outward to effect a dust-tight seal against the inside of the bag neck during filling. This is very common with FIBC bulk bag filler systems. Any of the Type 1 or Type 2 styles of Pneuma-Seal work very effectively in this application.
Mixer Lid Inflatable Seals with Square Corners
Pneuma-Seal inflatable seals can be configured with pre-molded 90 degree corners to effect leak-tight seals for hinged or sliding covers on access ways and other openings in mixers and other powder/bulk or fluid handling processing equipment. Type 1 style seals are best suited for this application.
Inflatable Seals for Butterfly Valve
Pneuma-Seal inflatable seals are ideal for butterfly valves in tight sealing applications. The clearance between the deflated seal allows for low torque rotation of the disk and eliminates the damaging effect of abrasion on the seal. When the disk is fully closed, the seal inflates radially inward against its edge to effect a leak-free condition.
Slide Gate Valve Inflatable Seals
Pneuma-Seal inflatable seals provide the tightest seal possible for controlling the flow of very fine materials. The valve seal does not inflate until the blade is firmly in position and then the seal inflates - creating a leak-free seal.
