Powder pneumatic diaphragm pump

The powder pneumatic diaphragm pump is a type of pump driven by compressed air,
specifically designed for conveying dry powders or bulk solids. It incorporates a
fluidization air circuit on the basis of a standard pneumatic diaphragm pump,
enabling the suction and stable delivery of powdered materials, making it suitable
for applications such as pigments, chemical powders, pharmaceutical powders, and
food powders.
How does it deliver the powder
The diaphragm reciprocates by air pressure: Compressed air enters the pump chamber,
driving the diaphragm to move back and forth. The change in pump chamber volume
creates suction, drawing in and discharging the powder.
The powder must be "fluidized" first: conventional diaphragm pumps are suitable for
liquid transportation but prone to powder accumulation. Therefore, dedicated powder
pumps introduce a small amount of fluidizing air at the powder inlet to maintain a
semi-fluid state of the powder before it is suctioned away.
The air circuits should be separated: The working air and fluidizing air should be
split into two separate lines immediately after leaving the air compressor,
connecting them to the pump's working port and fluidizing port respectively, to
avoid insufficient airflow, powder suction difficulties, or blockages caused by a
single air supply line.
characteristics
Anti-clogging Design: The fluidized air path combined with self-priming negative
pressure can reduce powder clumping and pipe blockages, ensuring smoother conveying
of lightweight powders such as silica, silica gel, titanium dioxide, starch, and
pigment powders.
Dust-free sealed conveying: The pump body and pipelines can be designed as a sealed
system to minimize dust leakage, reduce raw material waste and environmental
pollution, making it more suitable for industries such as pharmaceuticals, food,
and chemicals that require high cleanliness standards.
Explosion-proof safety: No electricity required, powered by compressed air, no
sparks generated, suitable for flammable and explosive powders or explosion-proof
workshops.
Low material damage: The pump has low shear forces, making it difficult for powder
particles to be damaged, making it suitable for powders with high particle
integrity requirements.
