Product Description:
These premium replacement diaphragms are specifically designed to fit ARO and Ingersoll Rand air-operated double-diaphragm (AODD) pumps. They are compatible with widely used models, including the BQG series that serves mining and industrial sectors. The product line accommodates various pump sizes, ranging from 1/2" to 3", matching diameters for models like the BQG450/0.2 as well as other standard ARO pumps.
Crafted from high-quality elastomers such as Santoprene™ (available in beige and black), NBR (black), F46 (white), and imported PTFE (white), these diaphragms ensure dependable sealing performance. They deliver excellent resistance to flex fatigue and boast a lengthy service life, even when operating under tough conditions. Whether you're managing abrasive slurries, chemical substances, oils, or fluids requiring high purity, we provide materials tailored to meet the demands of your specific application.
Each diaphragm is precisely molded with exact dimensions and includes integral studs where necessary, facilitating straightforward installation and a secure fit onto the pump shaft. Ideal for both original equipment manufacturer (OEM) replacements and maintenance inventory, these diaphragms help restore pump efficiency while reducing operational downtime.
Features:
Compatibility
These diaphragms serve as direct replacements for ARO and Ingersoll Rand pumps, including the BQG series models such as BQG450/0.2. They are also compatible with standard pump sizes ranging from 1/2" to 3" (including 1", 1.5", 2", and 3").
Multiple Material Options
A variety of materials are available to suit different operating conditions. Santoprene™ (beige or black) offers excellent flex fatigue resistance, strong chemical compatibility, and performs well over a wide temperature range. NBR (black) is resistant to oil and fuels and provides good abrasion resistance. For applications requiring superior chemical resistance and flexibility, F46 (white), a fluoropolymer, is an ideal choice. Additionally, PTFE (white, imported) provides maximum chemical inertness and is FDA-compliant, making it perfect for aggressive acids and high-purity applications.
Design and Performance
Each diaphragm features a precision-molded outer sealing lip that ensures leak-free operation. They also come with either an integral stud or center hole to provide a secure connection to the piston or shaft; however, compatibility depends on the specific pump model. The materials are color-coded for easy visual identification: beige indicates Santoprene, black represents NBR, and white corresponds to either F46 or PTFE.
Durability and Maintenance
Engineered for long flex life, these diaphragms can withstand millions of cycles in continuous duty environments. They are available as single diaphragms or matched pairs and can also be purchased as part of complete repair kits that include O-rings and gaskets. This makes maintenance cost-effective, reducing downtime and extending the service intervals of pumps.
Applications
These diaphragms are suitable for use in harsh environments such as mining, chemical plants, water treatment facilities, and food processing industries (when the correct materials are selected), ensuring reliable performance even under demanding conditions.
