Reliable Fluid Management: Air Operated Double Diaphragm AODD Pump By Macnaught Canada

Key Benefits of AODD Pump Technology: -

Integrating an AODD pump into your operational workflow
provides several mechanical advantages:

• High Output, Low Air Draw: The MAX FLOW series is specifically engineered to deliver the highest flow rates with the lowest air consumption in its class — helping reduce operating costs without sacrificing throughput.
• Damage-Free Dry Running: Macnaught's M3 AODD pumps are designed to run without fluid present and will not sustain damage if the pump runs dry unexpectedly — providing an important layer of protection in unpredictable field conditions.
• Automatic Self-Priming Operation: These pumps can prime from a dry start without manual intervention, even when the intake sits above the fluid surface,which simplifies setup and speeds up operation on site.
•  Adjustable Flow Output: Operators can modulate the flow rate simply by adjusting the incoming air supply — no additional controls or fittings required.
• Solids Passage Capability: The diaphragm design accommodates the passage of solid particles and abrasive material, making these pumps well-suited to waste oil recovery and slurry applications common in Canadian mining and
  construction environments.
• Reduced Maintenance Costs: Macnaught's M3 pumps feature a high-reliability closed-centre air valve that is serviceable while the pump remains online, and an epoxy-coated air section built to withstand tough environmental conditions. With fewer moving components than motor-driven alternatives, the long-term maintenance burden is significantly reduced.

Available AODD Pump Configurations

Macnaught Canada offers various builds to ensure
compatibility with different fluid types: -

1. Metallic Pumps: Built from Stainless Steel or Aluminium for heavy-duty industrial tasks and fuel transfer.
2. Non-Metallic (Plastic) Pumps: Constructed from Polypropylene or PVDF to provide maximum resistance against corrosive acids and chemicals.
3. High-Flow Models: Specialized equipment designed for high-volume fluid movement and waste oil management.
4. Small Port Models (1/2 " to 1"):Compact designs for precise dosing
5. Large Port Models (1.5" to 3"): High-capacity pumps used for
   wastewater management and large-scale remediation.

Its Industrial Applications: -

· Automotive & Fleet Maintenance: AODD pumps are commonly used in Canadian auto shops and fleet service operations to collect and transfer used engine oil, lubricants, and coolants.

·   Mining & Construction: Portable dewatering and slurry transfer in remote, electricity-free environments.

• Mining & Construction: Ideal for dewatering and slurry transfer at remote job sites across Canada’s northern territories.
• Chemical Processing: Polypropylene-bodied pumps are well-suited to moving corrosive fluids and chemical solutions without risk of degradation to pump components.
• Environmental Cleanup: Rapidly managing spill
  recovery and debris-heavy water.
• Environmental Response: Rapidly manages spill recovery and debris-laden water during site remediation.

Frequently Asked Questions

Q1. How does an AODD pump function?

 Powered by compressed air, the pump uses two alternating flexible diaphragms to create a vacuum. This draws fluid into the chamber and displaces it with every stroke, providing a leak-free transfer without any electrical power.

Q2. Are Macnaught pumps safe to run dry?

Yes. Our Max Flow series is engineered to run dry without
risk of damage. They do not produce heat in the absence of liquid, so accidental dry running will not compromise the pump’s integrity.

Q3. What types of liquids can these pumps move?

Depending on the materials chosen, these pumps can handle
everything from mining fluids, acids, and solvents to food-grade liquids, asphalt sealcoating, and hazardous waste streams.

Q4. What is the warranty coverage for the Max Flow
series?

The Max Flow AODD range includes a 5-year warranty on the
pump body.

Q5. Can I purchase repair kits for these units?

 Yes, Macnaught offers both Air Motor and Wet End service kits as service kits.
