Product Description:
This extensive selection of replacement diaphragms is specifically engineered to fit Wilden air-operated double-diaphragm (AODD) pumps in sizes 02, 04, 08, and 15. Each diaphragm serves as a direct OEM-equivalent component, ensuring compatibility and reliable performance.
The diaphragms come in three distinct high-quality materials, each identified by color for easy selection. The black diaphragm is made from NBR or Wil‑Flex™, which is suitable for general-duty oil and water applications. The beige diaphragm utilizes EPDM material, ideal for handling hot water and alkaline substances. For more demanding environments involving aggressive chemicals and high-purity requirements, the white PTFE diaphragm is the preferred choice.
Available models include the standard 51-series single-piece diaphragms, as well as the 52-series, 55-series, and 58-series variants. Additionally, there is a larger 15‑1020‑51 model designed for specialized applications. All diaphragms are precision-molded with integral studs, providing leak-free sealing, extended flex life, and straightforward installation.
Whether you need diaphragms for routine maintenance, urgent repairs, or to upgrade your pump system, this comprehensive range supports all common Wilden pump configurations. It helps restore operational efficiency and reliability across various sectors, including industrial, chemical, food processing, and sanitary operations.
Features:
Direct OEM Replacement for Wilden Pumps
This product line offers direct OEM replacement diaphragms compatible with Wilden pump models 02‑1010, 04‑1010, 08‑1010, 15‑1010, and 15‑1020. Designed to fit perfectly, these diaphragms ensure optimal pump performance and reliability.
Available Material Options
Customers can select from three distinct material types, each color-coded for easy identification:
- Black: Made from NBR (nitrile) or Wil‑Flex™, these diaphragms provide general-purpose resistance to oil, water, and fatigue.
- Beige/Yellowish: Constructed with EPDM, offering superior durability in applications involving hot water, steam, alkalis, and ozone.
- White: Fabricated from PTFE, these diaphragms are chemically inert, FDA-compliant, and suitable for handling acids and solvents.
Enhanced Features and Performance
Each diaphragm comes with an integral molded stud that ensures a positive drive connection, significantly reducing assembly time during installation. Engineered for longevity, they boast an outstanding flex life of more than 10 million cycles without cracking.
The precision sealing lip is designed to match the pump housing perfectly, guaranteeing zero leakage under operating conditions. Depending on the chosen material, these diaphragms can operate effectively across a wide temperature range from -40°C up to +120°C.
Versatile Options and Compliance
These diaphragms are available both as single units or matched pairs, allowing for a complete replacement solution tailored to your maintenance needs. When selecting the appropriate material, they are suitable for use in FDA, ATEX, and CE-certified environments.
Installation in the field is quick and straightforward, minimizing downtime and reducing maintenance costs for operational efficiency.
Compatibility
Our diaphragms are compatible with Wilden M, P, and PS pump series, available in the respective sizes to ensure seamless integration.
