ARO 1-1/2" Beige and Green Santoprene Diaphragm for Ingersoll Rand 40 Pump NBR PTFE FEP Rubber 94615，94616，94617，93459-4，92973-B

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 of 1/2", 1", 1.5", 2", and 3", ensuring seamless integration with your existing equipment.

We offer a variety of material choices to meet diverse application needs:

• Santoprene™ (beige/black) – Provides excellent flex fatigue resistance, outstanding chemical resistance, and operates effectively across a wide temperature range.
• NBR (black) – Known for its resistance to oil and fuels, along with good abrasion resistance.
• F46 (white) – A fluoropolymer material offering superior chemical resistance combined with excellent flexibility.
• PTFE (white, imported) – Offers maximum chemical inertness, is FDA-compliant, and is ideal for handling aggressive acids and applications requiring high purity.

The diaphragms feature a precision-molded outer sealing lip that ensures leak-free operation. Each diaphragm includes either an integral stud or a center hole to guarantee a secure connection to the piston or shaft; please verify the configuration according to your pump model.

Materials are color-coded for easy visual identification: beige indicates Santoprene, black corresponds to NBR, and white represents F46 or PTFE materials.

Engineered for long flex life, these diaphragms can withstand millions of cycles under continuous duty conditions. They are available either as single diaphragms or matched pairs and can also be purchased as part of comprehensive repair kits that include O-rings and gaskets.

Utilizing these diaphragms helps reduce downtime and extends the service intervals of your pumps, offering a cost-effective solution for maintenance.

Suitable for use in harsh environments, these diaphragms perform reliably in industries such as mining, chemical processing plants, water treatment, and food processing, provided that the materials selected are appropriate for the specific operating conditions.

The BQG series pumps are widely utilized in mining and mineral processing industries for various applications such as slurry transfer, tailings management, and dewatering processes. Their robust design ensures efficient handling of abrasive and dense materials.

In the chemical industry, these pumps are ideal for transferring aggressive fluids including acids, caustics, and solvents. Their compatibility with harsh chemicals makes them suitable for demanding chemical processing tasks.

The oil and gas sector benefits from the BQG series pumps for moving fuels, lubricants, and treating oily wastewater. Their reliable performance supports operational efficiency and environmental compliance.

Water and wastewater treatment facilities utilize these pumps to manage fluid transfer effectively, ensuring smooth processing and treatment operations.

In the food and beverage industry, the pumps handle edible oils, syrups, and juices, incorporating materials like PTFE and Santoprene to maintain hygiene and chemical resistance.

The pharmaceutical and cosmetic manufacturing sectors rely on these pumps for precise and clean fluid handling, supporting high standards of product purity and quality.

Circulation of paints, inks, and coatings is another common application, where the pumps deliver consistent flow and maintain the integrity of the materials.

Ceramic and glaze production processes also benefit from the reliable pumping of viscous and abrasive fluids provided by these pumps.

Lastly, the BQG series pumps serve general industrial fluid transfer needs, handling water, emulsions, and light chemicals efficiently across various applications.
