Vacuum Feeder, VP Series
Powder handling glovebox for safe handling of potent powders and charging reactors in a sealed manner
The VP series vacuum feeder consists of a vacuum system, back-blow cleaning system, filtration system, inlet butterfly valve, and discharge butterfly valve. The vacuum system can be configured either with a built-in pneumatic vacuum pump or an external vacuum source.
Under negative pressure generated by the vacuum system, materials are drawn through the suction pipe into the storage hopper. The integrated filter separates air from solid particles, preventing powder from entering the vacuum unit. The feeder operates automatically in a suction–discharge–back-blow cycle, ensuring continuous and efficient conveying. Explosion-proof versions are available for transferring reactive media to reactors or mixing tanks.
The VP vacuum feeder is widely used for enclosed conveying of powders, granules, and small flakes, especially in industries with stringent cleanliness requirements such as pharmaceuticals, food additives, and fine chemicals.
