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 favored in mining and industrial sectors. Our product range supports various pump sizes, spanning from 1/2" up to 3", fitting models such as the BQG450/0.2 and other common ARO pump types.
Crafted from high-quality elastomer materials, these diaphragms come in several varieties including Santoprene™ (available in beige and black), NBR (black), F46 (white), and imported PTFE (white). Each material is chosen to ensure exceptional sealing performance, outstanding resistance to flex fatigue, and durability even under harsh operating conditions.
Whether your application involves abrasive slurries, aggressive chemicals, oils, or fluids requiring high purity, we provide diaphragms made from the optimal material to match your specific fluid media. The diaphragms are precision-molded with exact dimensions and come equipped with integral studs where necessary, facilitating straightforward installation and secure connection to the pump shaft.
These diaphragms serve as excellent solutions for both original equipment manufacturer (OEM) replacements and maintaining your existing inventory. By using our diaphragms, you can effectively restore pump performance and reduce operational downtime, ensuring continuous and efficient pump function.
Features:
Compatibility
These diaphragms serve as a direct replacement for ARO and Ingersoll Rand pumps, including the BQG series such as BQG450/0.2. They fit a variety of standard pump sizes including 1/2", 1", 1.5", 2", and 3".
Multiple Material Options
We offer diaphragms in various materials to suit different application needs. Santoprene™ (beige/black) provides excellent flex fatigue resistance, chemical durability, and operates effectively across a wide temperature range.
NBR (black) is designed for oil and fuel resistance while also offering good abrasion protection.
F46 (white) is a fluoropolymer that delivers superior chemical resistance along with flexibility.
PTFE (white, imported) stands out with maximum chemical inertness, is FDA-compliant, making it ideal for handling aggressive acids and high-purity applications.
Design Features
Each diaphragm includes a precision-molded outer sealing lip that guarantees leak-free operation.
They come with an integral stud or a center hole for a secure connection to the piston or shaft, depending on the specific pump model.
The materials are color-coded for easy visual identification: beige represents Santoprene, black corresponds to NBR, and white is for F46 or PTFE.
Durability and Maintenance
These diaphragms are engineered for long flex life, capable of withstanding millions of cycles under continuous duty conditions.
Available as single diaphragms or matched pairs, they can also be purchased as part of comprehensive repair kits which include O-rings and gaskets.
Their cost-effective design helps reduce downtime and extends the overall service intervals of pumps.
