WILDEN 15 Series Outer Diameter 305 mm Pump Size 3″ PTFE Composite Diaphragm 15

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 optimal performance for your pumping systems.

The diaphragms are offered in three distinct, high-quality materials, each easily identified by color coding: black diaphragms are made from NBR or Wil‑Flex™ and are suitable for general-duty oil and water applications; beige diaphragms utilize EPDM, ideal for hot water and alkaline environments; while white diaphragms consist of PTFE, designed to withstand aggressive chemicals and support high-purity processes.

Available models include the standard 51‑series single-piece diaphragms, along with the 52‑series, 55‑series, and 58‑series variants. Additionally, there is the larger 15‑1020‑51 model tailored for specialized applications. Each diaphragm is precision-molded with integral studs to guarantee leak-free sealing, extended flex life, and straightforward installation.

Whether you need these diaphragms for routine maintenance, urgent repairs, or upgrading your pumps, this comprehensive range addresses all common Wilden pump configurations. It helps restore both efficiency and reliability across diverse industries, including industrial manufacturing, chemical processing, food production, and sanitary operations.

Features:

These diaphragms are designed as direct OEM replacements for Wilden pump models 02‑1010, 04‑1010, 08‑1010, 15‑1010, and 15‑1020. They ensure perfect compatibility and optimal performance for your equipment.

Our diaphragms come in three distinct material options, each color-coded for easy identification:

• Black: Made from NBR (nitrile) or Wil‑Flex™, ideal as a general-purpose material with high resistance to oil, water, and fatigue.
• Beige/Yellowish: Crafted from EPDM, this material offers superior performance when exposed to hot water, steam, alkalis, and ozone.
• White: Constructed from PTFE, which is chemically inert, FDA-compliant, and excels at handling acids and solvents.

Each diaphragm includes an integral molded stud for a positive drive connection, which significantly reduces assembly time. The product is engineered to deliver outstanding flex life, capable of enduring over 10 million cycles without cracking. Additionally, the precision sealing lip is designed to perfectly match the pump housing, ensuring zero leakage for reliable operation.

These diaphragms operate effectively over a wide temperature range, from -40°C up to +120°C, depending on the material selected. They are available as individual diaphragms or matched pairs, allowing for complete pump replacements tailored to your needs.

Suitable for use in FDA-regulated, ATEX-zone, and CE-certified environments when the correct material is chosen. The diaphragms facilitate quick field replacement, minimizing equipment downtime and reducing associated maintenance costs.

Compatibility extends across the Wilden M, P, and PS pump series in their respective sizes, ensuring seamless integration and enhanced pump performance.

Applications:

Chemical processing involves handling a variety of substances including acids, caustics, solvents, and other aggressive fluids. These processes require specialized equipment capable of withstanding harsh chemical environments.

Water and wastewater treatment is an essential sector focused on the purification and management of water resources. This includes the removal of contaminants and the treatment of sewage to protect public health and the environment.

The food and beverage industry encompasses the production of items such as juices, syrups, edible oils, and dairy products. Pumps and fluid transfer systems in this sector must comply with strict hygiene standards to ensure product safety and quality.

Pharmaceutical and cosmetic manufacturing demands precision and cleanliness in the movement and processing of fluids. Equipment used here must meet regulatory requirements to maintain product integrity.

In paint, ink, and coating circulation, the handling of viscous and sometimes abrasive fluids requires robust systems designed to maintain consistent flow and prevent clogging or degradation of materials.

The mining industry involves the transport and processing of mineral slurries, which are mixtures of solids and liquids. Pumps used must be durable and capable of handling abrasive materials without frequent maintenance.

Oil, fuel, and lubricant transfer is a critical operation in many industrial settings, necessitating equipment that can safely and efficiently move these fluids while preventing leaks and contamination.

Ceramic and glaze pumping plays a key role in manufacturing processes where precise application and handling of viscous materials are required to achieve the desired product finish and quality.

Industrial cleaning and surface treatment utilize various fluids to prepare or treat surfaces, often involving aggressive chemicals that require specialized pumps resistant to corrosion and wear.

General fluid transfer includes the movement of water, light oils, and emulsions in a variety of applications. Flexible and reliable pumping solutions are essential to accommodate different fluid characteristics and system demands.
