Product Description:
These premium replacement diaphragms are specifically designed to fit ARO and Ingersoll Rand air-operated double-diaphragm (AODD) pumps. This includes the widely used BQG series, which is favored in mining and various industrial applications. The product line accommodates pump sizes ranging from 1/2" up to 3", covering diameters that match models like the BQG450/0.2 as well as other standard ARO pump models.
Crafted from high-grade elastomers such as Santoprene™ (available in beige and black), NBR (black), F46 (white), and imported PTFE (white), these diaphragms ensure dependable sealing and outstanding resistance to flex fatigue. Their durable construction guarantees a long service life even under the most demanding operational conditions.
Whether your application involves handling abrasive slurries, harsh chemicals, oils, or fluids requiring high purity, we provide diaphragm materials tailored to suit the specific media. Each diaphragm is precisely molded with careful attention to dimensions and includes integral studs when applicable, simplifying installation and ensuring a secure fit to the pump shaft.
Perfect for use as OEM replacements or as part of your maintenance inventory, these diaphragms help restore pump performance while reducing downtime, making them an excellent choice for maintaining operational efficiency.
Features:
Compatibility
These diaphragms serve as a direct replacement for ARO and Ingersoll Rand pumps, including the BQG series such as BQG450/0.2 and other standard pump sizes like 1/2", 1", 1.5", 2", and 3".
Multiple Material Options
The diaphragms are available in a variety of materials to suit different applications:
- Santoprene™ (beige/black): Offers excellent flex fatigue resistance, strong chemical resistance, and a broad temperature operating range.
- NBR (black): Designed for oil and fuel resistance with good abrasion resistance.
- F46 (white): A fluoropolymer that provides superior chemical resistance while maintaining excellent flexibility.
- PTFE (white, imported): Provides maximum chemical inertness, is FDA-compliant, and ideal for handling aggressive acids and applications requiring high purity.
Enhanced Features
Each diaphragm includes a precision-molded outer sealing lip that guarantees leak-free operation. Additionally, an integral stud or center hole design ensures a secure connection to the piston or shaft—please verify your specific pump model for compatibility.
The materials are color-coded for easy visual identification: beige for Santoprene, black for NBR, and white for F46 or PTFE.
Durability and Cost Efficiency
Engineered for longevity, these diaphragms can endure millions of flex cycles, making them suitable for continuous-duty operation. They are available as single diaphragms, matched pairs, or as part of comprehensive repair kits including O-rings and gaskets.
Utilizing these diaphragms enhances maintenance cost-effectiveness by minimizing downtime and extending pump service intervals.
