    • 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.

    The powder processing and palletizing equipment is widely used in pharmaceutical, food, and chemical applications. Selection can be made based on material type (e.g. wet, dry, or fragile), flowability, and target throughput. Based on these parameters, a suitable model and configuration are recommended for the intended process.

    Our powder handling equipment can be built using high-temperature-resistant, corrosion-resistant, and explosion-proof designs. Typical options include 316L stainless steel construction, PTFE sealing, explosion-proof motors, and nitrogen inerting systems.

    Our powder processing machines are designed in line with GMP requirements. Product-contact surfaces can be supplied in SS304 or SS316L with polished finishes down to Ra ≤ 0.4 μm, suitable for installation in clean production areas.

    Complete lines can be tailored, including equipment footprint, capacity range, and inlet/outlet height, to achieve direct integration into existing processes.

    Voltage and frequency can be supplied according to regional standards (for example 220 V / 380 V / 415 V, 50 Hz / 60 Hz). Control systems can include PLC and HMI with Siemens or Schneider electrical components.
