Product Description:
These high-quality replacement diaphragms are specifically designed to be compatible with ARO and Ingersoll Rand air-operated double-diaphragm (AODD) pumps. This includes popular models such as the BQG series, which are widely used in mining and various industrial applications.
The product range accommodates pump sizes ranging from 1/2 inch to 3 inches. It also covers diaphragm diameters that match models like the BQG450/0.2, as well as other standard ARO pump types, ensuring broad compatibility across different equipment.
Crafted from premium elastomer materials such as Santoprene™ (available in beige and black), NBR (black), F46 (white), and imported PTFE (white), these diaphragms deliver outstanding sealing performance. They offer excellent resistance to flex fatigue and are built to endure long service life even in challenging operating conditions.
Whether your application involves handling abrasive slurries, aggressive chemicals, oils, or high-purity fluids, we provide diaphragms made from the appropriate materials tailored to your specific media requirements.
Each diaphragm is manufactured with precision-molded dimensions and features integral studs where applicable, facilitating simple installation and secure attachment to the pump shaft. These replacement parts are ideal for both OEM servicing and stocking for maintenance purposes.
By installing these diaphragms, you can effectively restore pump efficiency and significantly reduce downtime, ensuring reliable performance in demanding industrial environments.
Features:
Compatibility
These diaphragms are designed as direct replacements for ARO and Ingersoll Rand pumps, including the BQG series such as BQG450/0.2. They are compatible with standard pump sizes including 1/2", 1", 1.5", 2", and 3", ensuring a wide range of applications.
Multiple Material Options
Several material choices are available to meet different operational requirements:
- Santoprene™ (beige/black): Offers excellent flex fatigue endurance, strong chemical resistance, and operates effectively across a wide temperature range.
- NBR (black): Known for its resistance to oil and fuel, with good abrasion resistance properties.
- F46 (white): A fluoropolymer that provides superior chemical resistance and flexibility, ideal for challenging environments.
- PTFE (white, imported): Provides maximum chemical inertness and is FDA-compliant, making it suitable for aggressive acids and high-purity applications.
Design Features
The diaphragms feature a precision-molded outer sealing lip that guarantees leak-free performance. They also have an integral stud or center hole to ensure a secure connection to the piston or shaft, depending on the pump model.
Additionally, the materials are color-coded for easy visual identification: beige represents Santoprene, black corresponds to NBR, and white indicates either F46 or PTFE.
Performance and Maintenance
Engineered for durability, these diaphragms offer a long flex life capable of handling millions of cycles in continuous duty. They are available both as single diaphragms and matched pairs, as well as within complete repair kits including O-rings and gaskets.
This design promotes cost-effective maintenance by minimizing downtime and extending intervals between pump servicing.
Application Suitability
These diaphragms are suitable for use in harsh environments such as mining operations, chemical plants, water treatment facilities, and food processing industries, provided the appropriate material choice is selected.

Applications:
The mining and mineral processing industries rely on specialized pumps for various applications such as slurry transfer, managing tailings, and dewatering processes. The BQG series pumps are well-suited for these demanding tasks, ensuring efficient and reliable operation.
In the field of chemical processing, handling aggressive fluids like acids, caustics, and solvents requires pumps that can withstand harsh conditions. These pumps are designed to provide excellent corrosion resistance and durability.
The oil and gas sector utilizes pumps for transferring fuels, lubricants, and managing oily wastewater. These pumps play a crucial role in maintaining smooth operations and environmental compliance.
Water and wastewater treatment facilities benefit from pumps that can handle various fluid types to support treatment processes and ensure effective water management.
Within the food and beverage industry, pumps equipped with PTFE or Santoprene components are used for transferring edible oils, syrups, and juices. These materials help maintain product purity and meet sanitary requirements.
Pharmaceutical and cosmetic manufacturing also depends on reliable pumps for precise fluid transfer, contributing to product quality and safety.
In addition, the circulation of paints, inks, and coatings requires specialized pumps that ensure consistent flow and prevent contamination during production.
Ceramic and glaze pumping involves materials that demand robust and reliable pumps to handle viscous and abrasive fluids effectively.
Finally, general industrial fluid transfer covers a wide range of applications, including the movement of water, emulsions, and light chemicals, all of which benefit from adaptable and efficient pump solutions.
