Product Description:
These premium replacement diaphragms are specifically designed to be compatible with ARO and Ingersoll Rand air-operated double-diaphragm (AODD) pumps. This includes the widely used BQG series, which is popular in mining and various industrial applications. The product line accommodates pump sizes ranging from 1/2 inch up to 3 inches, fitting models such as the BQG450/0.2 and other common ARO pump variants.
Crafted from high-quality elastomer materials, these diaphragms utilize options like Santoprene™ (available in beige and black), NBR (black), F46 (white), and imported PTFE (white). These material choices ensure dependable sealing performance, outstanding resistance to flex fatigue, and extended durability even under rigorous operating conditions. Whether your process involves abrasive slurries, aggressive chemicals, oils, or fluids requiring high purity, we have the appropriate diaphragm material to meet your application’s demands.
Each diaphragm is produced with precision-molded dimensions and comes equipped with integral studs where necessary, allowing for straightforward installation and a secure attachment to the pump shaft. These replacement diaphragms are ideal both for original equipment manufacturer (OEM) parts replacement and for maintaining inventory in service operations. By using these diaphragms, you can restore the efficiency of your pumps and significantly reduce downtime.
Features:
Compatibility
These diaphragms serve as a direct replacement for ARO and Ingersoll Rand pumps, including the BQG series such as BQG450/0.2, as well as standard pump sizes ranging from 1/2" to 3" (1/2", 1", 1.5", 2", 3").
Multiple Material Options
We offer a variety of material choices to suit different operational needs:
- Santoprene™ (beige/black): Known for excellent flex fatigue resistance, chemical resistance, and a broad temperature range.
- NBR (black): Provides resistance against oil and fuel, along with good abrasion durability.
- F46 (white): A fluoropolymer featuring superior chemical resistance and flexibility.
- PTFE (white, imported): Offers maximum chemical inertness, is FDA-compliant, and ideal for aggressive acids as well as high-purity applications.
Design Features
The diaphragms incorporate a precision-molded outer sealing lip that guarantees leak-free operation. An integral stud or center hole is available for a secure piston or shaft connection; availability depends on the specific pump model.
For easy visual identification, materials are color-coded: beige represents Santoprene, black indicates NBR, and white corresponds to F46 or PTFE.
Durability and Availability
Engineered for long flex life, these diaphragms can endure millions of cycles in continuous duty environments. They are available as single diaphragms or matched pairs, and can also be purchased as part of comprehensive repair kits that include O-rings and gaskets.
Cost-Effective and Versatile
Designed for cost-effective maintenance, these diaphragms help reduce downtime and extend pump service intervals. They are suitable for use in harsh environments such as mining operations, chemical plants, water treatment facilities, and food processing industries when using appropriate materials.
