Product Description:
These top-quality 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 popular in mining and various industrial applications. The available sizes cover pump diameters ranging from 1/2" up to 3", accommodating models like the BQG450/0.2 as well as other standard ARO pump variants.
Crafted from premium elastomer materials such as Santoprene™ (available in beige or black), NBR (black), F46 (white), and imported PTFE (white), these diaphragms ensure dependable sealing and outstanding resistance to flex fatigue. Their robust construction guarantees a long operational life even under challenging conditions.
Whether you are pumping abrasive slurries, various chemicals, oils, or high-purity fluids, these diaphragms come in materials suitable for your specific media requirements. Each part is precision molded to exact dimensions and includes integral studs when necessary, facilitating easy installation and secure attachment to the pump shaft.
Ideal for both original equipment manufacturer (OEM) replacements and maintenance inventories, these diaphragms help restore pump performance while minimizing operational downtime. Their reliable design makes them an excellent choice to maintain the efficient functioning of your AODD pumps.
Features:
Compatibility
These diaphragms serve as direct replacements for ARO and Ingersoll Rand pumps, including the BQG series such as BQG450/0.2, along with standard pump sizes of 1/2", 1", 1.5", 2", and 3". They are designed to fit seamlessly, ensuring optimal performance without modifications.
Multiple Material Options
The diaphragms are available in a variety of materials to suit different operational requirements:
- Santoprene™ (beige/black): Offers excellent flex fatigue resistance, broad chemical compatibility, and performs well across a wide temperature range.
- NBR (black): Known for its resistance to oils and fuels, combined with good abrasion resistance.
- F46 (white): A fluoropolymer that provides superior chemical resistance along with flexibility.
- PTFE (white, imported): Exhibits maximum chemical inertness, is FDA-compliant, and is ideal for applications involving aggressive acids and high purity requirements.
Design Features
Each diaphragm includes a precision-molded outer sealing lip that guarantees leak-free operation. The design incorporates either an integral stud or a center hole, depending on the pump model, to provide a secure piston or shaft connection.
Color-coded materials simplify identification: beige indicates Santoprene, black denotes NBR, and white represents F46 or PTFE variants. This coding helps in quick and accurate material selection.
Performance and Maintenance
Engineered for durability, these diaphragms deliver a long flex life, capable of withstanding millions of cycles in continuous usage. 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.
The use of these diaphragms supports cost-effective maintenance by minimizing downtime and extending the intervals between service. Their robust construction makes them suitable for operation in harsh environments such as mining, chemical processing plants, water treatment facilities, and food processing setups—provided the correct material is selected for the application.
