How Pneumatic Powder Pumps Work?

 What Is a Pneumatic Powder Pump?

A pneumatic powder pump uses compressed air to transfer dry powders safely and efficiently. ARO powder pumps handle powders with densities up to 721 kg/m³ (45 lb/ft³), including:

• Carbon black
• Expanded mica
• Silicones
• Acrylic resins
• 3D printing powders
• Pharma ingredients

Key Specifications:

• Pump Ratio: 1:1
• Sizes: Available in 2'' and 3'' options
• Maximum Particle Sizes:
• • 6.4 mm (0.25 in) for 2'' pumps
  • 9.5 mm (0.37 in) for 3'' pumps
• Maximum Pressure: 6.9 bar (100 psi)
• Materials: Aluminum or stainless steel

Weight:

• 2'' Aluminum Pump: 41.5 kg (91.5 lbs)
• 3'' Aluminum Pump: 62.4 kg (137.5 lbs)
• 2'' Stainless Steel Pump: 71.6 kg (157.8 lbs)
• 3'' Stainless Steel Pump: 107.4 kg (236.8 lbs)

How Do Pneumatic Powder Pumps Work?

ARO powder pumps operate through a simple yet effective process:

1. Fluidization: Compressed air fluidizes the powder, making it easier to move.
2. 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.
3. Patented Air-Induction System: This unique system prevents powder pack-out and optimizes powder aeration for consistent flow.
4. Built-in Delay Timer: Ensures proper fluidization before start-up, reducing downtime.
5. 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.

How to Install a Pneumatic Powder Pump?

ARO powder pumps are designed for easy and flexible installation:

• Portable Design: Can be moved between sites or mounted on existing equipment.
• Air Supply: Ensure a stable and filtered compressed air source for optimal performance.
• Secure Connections: Properly connect the air supply and powder intake to prevent leaks and ensure smooth operation.

Included Components:

• Air Filter/Regulator: Maintains clean and regulated air supply for consistent performance.
• Flexible installation in harsh environments, including in hazardous duty areas (ATEX).
