Product Description:
These premium replacement diaphragms are specifically designed to fit ARO and Ingersoll Rand air-operated double-diaphragm (AODD) pumps. This includes compatibility with the widely used BQG series, which is favored in mining and industrial settings. The product line accommodates pump sizes ranging from 1/2" up to 3", covering models such as the BQG450/0.2 as well as other standard ARO pump variants.
Constructed from high-quality elastomers, these diaphragms utilize materials like Santoprene™ (available in beige and black), NBR (black), F46 (white), and imported PTFE (white). This selection of materials ensures dependable sealing performance, outstanding resistance to flex fatigue, and extended service life, even under tough operating conditions. Whether dealing with abrasive slurries, chemical substances, oils, or ultra-pure fluids, the appropriate material is available to meet the demands of your specific application.
Each diaphragm is precisely molded to exact specifications and includes integral studs where applicable. These features allow for straightforward installation and secure attachment to the pump shaft. Designed to serve both as genuine OEM replacements and as part of regular maintenance inventories, these diaphragms help restore pump efficiency and reduce operational downtime effectively.
Features:
Compatibility
These diaphragms serve as a direct replacement for ARO and Ingersoll Rand pumps, including models from the BQG series such as BQG450/0.2. They also fit standard pump sizes ranging from 1/2" up to 3". This broad compatibility ensures seamless integration with a variety of existing pump systems.
Multiple Material Options
Customers can choose from several high-quality materials tailored to specific application needs:
- Santoprene™ (beige/black): Known for excellent flex fatigue resistance, strong chemical resistance, and a wide operational temperature range.
- NBR (black): Offers oil and fuel resistance along with good abrasion resistance, making it suitable for demanding environments.
- F46 (white): A fluoropolymer providing superior chemical resistance combined with excellent flexibility.
- PTFE (white, imported): Delivers maximum chemical inertness; FDA-compliant and ideal for handling aggressive acids and applications requiring high purity.
Design Features
Each diaphragm includes a precision-molded outer sealing lip to guarantee leak-free operation. Additionally, they feature either an integral stud or a center hole to ensure a secure piston or shaft connection, depending on the pump model.
The color-coded materials facilitate easy visual identification: beige represents Santoprene, black indicates NBR, and white corresponds to either F46 or PTFE materials.
Durability and Availability
Engineered for longevity, these diaphragms provide a long flex life designed to withstand millions of cycles in continuous-duty applications. They are available both as single diaphragms or matched pairs, and can also be purchased as part of comprehensive repair kits that include O-rings and gaskets.
Cost-effectiveness and Application
These products offer cost-effective maintenance solutions by reducing downtime and extending the service intervals of pumps. They are well suited for use in harsh environments such as mining operations, chemical plants, water treatment facilities, and food processing plants when the appropriate materials are selected.

Packing and Shipping:
Product Packaging and Shipping for Pulse Valve Diaphragm
Each pulse valve diaphragm is carefully packaged to ensure maximum protection during transit. The diaphragm is first placed in a sealed plastic bag to prevent contamination from dust, moisture, or other environmental factors. It is then cushioned with foam or bubble wrap to absorb shocks and vibrations.
The protected diaphragm is placed inside a sturdy cardboard box that is appropriately sized to minimize movement within the box. Multiple units may be packed together with additional padding between each item to avoid damage.
For bulk orders, the individual boxes are consolidated into larger cartons or wooden crates, depending on the quantity and shipping requirements. The outer packaging is clearly labeled with product information, handling instructions, and shipping details.
Shipping is carried out through reliable carriers to ensure timely and safe delivery. We offer various shipping options including air freight, sea freight, and express courier services, tailored to the customer's needs.
All shipments are accompanied by detailed documentation including packing lists, invoices, and certificates of quality to facilitate smooth customs clearance and inventory management.
