Product Description:
This extensive selection of replacement diaphragms is specifically engineered to fit Wilden air-operated double-diaphragm (AODD) pumps in various sizes including 02, 04, 08, and 15. Each diaphragm serves as a direct OEM-equivalent component, ensuring compatibility and optimal performance.
The diaphragms are offered in three distinct high-performance materials, each easily recognizable by its color coding: black diaphragms are made from NBR or Wil‑Flex™ suitable for general-duty oil and water applications; beige diaphragms utilize EPDM, ideal for handling hot water and alkalis; and white diaphragms are constructed from PTFE, designed for use with aggressive chemicals and in high-purity environments.
Available models include the standard 51-series single-piece diaphragms as well as variants from the 52-series, 55-series, and 58-series. Additionally, there is the larger 15-1020-51 diaphragm tailored for specialized applications. These diaphragms are precision-molded with integral studs, which guarantee leak-free sealing, an extended flex life, and straightforward installation.
Whether you need these diaphragms for routine maintenance, emergency repairs, or pump upgrades, this comprehensive collection covers all common Wilden pump configurations. Utilizing these diaphragms helps restore efficiency and reliability across a wide range of applications including industrial, chemical, food processing, and sanitary operations.
Features:
These diaphragms serve as direct OEM replacements for Wilden pumps, specifically compatible with models 02‑1010, 04‑1010, 08‑1010, 15‑1010, and 15‑1020. Designed to fit seamlessly, they ensure optimal performance and reliability in pump operation.
Customers can choose from three distinct material options, each identified by a unique color code. The black variant is made from either NBR (nitrile) or Wil‑Flex™, which is ideal for general-purpose applications due to its resistance to oil, water, and fatigue. The beige or yellowish option is crafted from EPDM, offering superior durability when exposed to hot water, steam, alkalis, and ozone. Lastly, the white version is composed of PTFE, a chemically inert and FDA-compliant material that effectively handles acids and solvents.
Each diaphragm features an integral molded stud for a positive drive connection, streamlining the assembly process and reducing installation time. Engineered for longevity, these diaphragms exhibit outstanding flex life, capable of enduring more than 10 million cycles without cracking.
The precision sealing lip is designed to perfectly match the pump housing, providing a leak-free seal. Depending on the chosen material, the diaphragms can operate efficiently across a wide temperature range, from as low as -40°C up to +120°C.
Available as either single diaphragms or matched pairs, they offer complete replacement solutions. These products are suitable for use in FDA, ATEX, and CE-certified environments, provided the appropriate material is selected for the specific application.
Quick field replacement capabilities help minimize downtime and reduce maintenance costs. Furthermore, these diaphragms are compatible with the Wilden M, P, and PS pump series in their respective sizes, ensuring versatile applicability across a range of equipment.

Applications:
Chemical processing involves the handling and movement of various substances such as acids, caustics, solvents, and other aggressive fluids. These processes require specialized equipment designed to withstand harsh chemical environments.
Water and wastewater treatment is another critical application area, where fluids are managed to ensure environmental standards and public health. Efficient pumping and transfer systems play a vital role in these treatment processes.
The food and beverage industry includes the manufacturing of products like juices, syrups, edible oils, and dairy. In this sector, hygiene and precision in fluid handling are essential to maintain product quality and safety.
Pharmaceutical and cosmetic production also demands careful fluid management, ensuring that ingredients are transferred safely and accurately during the manufacturing stages.
Circulation of paints, inks, and coatings requires pumps and systems that can deal with viscous and sometimes abrasive fluids, ensuring consistent application and quality.
In mining operations, the handling of mineral slurries is a common challenge. Specialized equipment is used to transport these heavy and abrasive mixtures efficiently.
Transferring oil, fuel, and lubricants is essential in many industries, demanding pumps that can safely manage these flammable and viscous fluids.
Ceramic manufacturing involves glaze pumping, where consistent and controlled fluid transfer is crucial to product finish and quality.
Industrial cleaning and surface treatment processes rely on effective fluid management to deliver cleaning agents and treatment chemicals precisely where needed.
Finally, general fluid transfer covers a wide range of applications including water, light oils, and emulsions, requiring versatile and reliable pumping solutions.
