How Do Pneumatic Powder Pumps Work?

ARO powder pumps operate through a simple yet effective process:

Fluidization: Compressed air fluidizes the powder, making it easier to move.
Suction and Discharge: The pump’s diaphragms move back and forth, creating alternating suction and discharge cycles. This action draws the fluidized powder into the chamber and pushes it out through the discharge port.
Patented Air-Induction System: This unique system prevents powder pack-out and optimizes powder aeration for consistent flow.
Built-in Delay Timer: Ensures proper fluidization before start-up, reducing downtime.
4-Way Air-Efficiency Valve: Minimizes air consumption, reducing costs and energy use.

Additional Features or ARO powder pumps are:

Main Air Control Valve: Directly controlled by the delay timer for precise start-up.
Stall-Free Air Valve: Ensures continuous, reliable operation without interruptions.

Frequently Asked Questions About Powder Pumps

An ARO pneumatic powder pump uses compressed air to fluidize and transfer dry powders. Fluidization introduces air into the powder, making the material easier to move. Reciprocating diaphragms then create alternating suction and discharge cycles inside the pump. These cycles draw fluidized powder inward and push it through the discharge port. A patented air-induction system supports aeration and helps prevent powder pack-out.
