Transferring oils and lubricants reliably requires pumps that can handle varying viscosities, operate safely, and minimise downtime. For many industrial applications, air-operated double diaphragm (AODD) pumps are a proven and practical solution.
Why AODD Pumps Are Well Suited to Oils & Lubricants
AODD pumps use compressed air to move fluid via two flexible diaphragms connected by a central shaft. As one chamber fills, the other discharges, creating a continuous and controlled flow.
This simple operating principle makes AODD pumps:
- Easy to service and repair
- Reliable in demanding industrial environments
- Suitable for a wide range of oil and lubricant types
Key Benefits for Oil Transfer Applications
AODD pumps are commonly used to transfer mineral oils, hydraulic oils and food-grade lubricants because they offer:
- Leak-free operation
- Self-priming and dry-running capability
- Adjustable flow rates
- Multiple elastomer options for chemical compatibility
- Rugged metallic construction for industrial use
These features allow many facilities to standardise on a single pump technology across multiple oil transfer duties.
Metallic AODD Pumps for Industrial Use
Metallic AODD pumps are widely used for general-purpose oil and lubrication transfer where durability and performance are essential.
Allflo metallic AODD pumps are available in aluminium, anodised aluminium and stainless steel to suit different corrosion and abrasion requirements. Stainless steel models are typically selected where higher chemical resistance or harsher operating conditions are present.
Common applications include:
- Lubrication systems
- Hydraulic oil transfer
- Bulk oil handling
- Maintenance and service operations
Selecting the Right Pump
Choosing the correct AODD pump depends on factors such as:
- Fluid viscosity and temperature
- Required flow rate
- Chemical compatibility of elastomers
- Operating environment
Reviewing a chemical compatibility chart is essential to ensure long service life and reliable operation.
