Product Description:
This extensive collection of replacement diaphragms is meticulously engineered to be compatible with Milton Roy mechanical and hydraulic diaphragm metering pumps. It includes models from the widely used GM series, ranging from GM0002 to GM1200, the GB series covering GB0350 to GB1800, as well as the mRoy MRA and MRB models.
Crafted from premium materials such as virgin PTFE and F46 fluoropolymer, these diaphragms deliver outstanding chemical resistance, exceptional durability with a long flex life, and dependable sealing performance in challenging dosing scenarios.
The GM and GB series employ mechanically actuated PTFE diaphragms, capable of handling flow rates up to 1800 liters per hour and pressures reaching 12 bar. Meanwhile, the mRoy MRA and MRB series feature hydraulically balanced PTFE diaphragms designed to achieve operating lifespans of up to 96,000 hours.
Whether you require a single diaphragm for urgent repairs or a comprehensive service kit for routine maintenance, this product range offers OEM-quality replacement parts. These components help maintain pump efficiency and reduce downtime across various industries, including water treatment, chemical processing, and industrial dosing applications.
Features:
These diaphragms offer broad compatibility and are designed to fit a wide range of Milton Roy models. They are suitable for use with the GM series (GM0002–GM1200), the GB series (GB0350–GB1800), as well as the mRoy MRA and MRB models, ensuring versatile application across different pump types.
Constructed from premium materials, the diaphragms feature virgin PTFE, which provides maximum chemical inertness, complies with FDA standards, and exhibits excellent non-stick properties. Additionally, this material withstands temperatures up to +150°C, making it highly durable under demanding conditions.
Another key material used is F46 fluoropolymer, which offers superior chemical resistance while providing enhanced flexibility compared to standard PTFE. This makes it ideal for applications requiring both robustness and adaptability.
The design varies depending on the pump type. For the GM and GB series, a mechanically actuated design is employed, utilizing a robust PTFE diaphragm to ensure reliable dosing performance. In contrast, the mRoy MRA and MRB models use a hydraulically balanced design, featuring a PTFE diaphragm known for its extended operating life of up to 96,000 hours. This design eliminates the need for seal and plunger packing maintenance, reducing downtime.
Each diaphragm is precision molded to guarantee an accurate fit and effective sealing against pump heads. They come as integral studs or assemblies, which include the diaphragm plate, O-ring, and screw where applicable, providing a complete solution for replacement needs.
For ease of identification, PTFE diaphragms are color-coded in white or off-white. Customers can choose between purchasing single diaphragms or full service kits, which include O-rings, gaskets, and seals, allowing for comprehensive maintenance.
Engineered for long service life, these diaphragms are capable of millions of cycles in continuous duty environments. Their chemical resistance and sanitary design make them well-suited for aggressive chemicals, high-purity processes, and applications demanding strict hygiene standards.

Support and Services:
Our Pulse Valve Diaphragm product is designed to deliver reliable performance and long service life in demanding industrial applications. To ensure optimal operation, it is important to follow proper installation, maintenance, and troubleshooting procedures.
For installation, make sure the diaphragm is correctly positioned and securely fastened to prevent air leaks and ensure efficient pulse jet cleaning. Use only compatible materials and avoid overtightening, which can cause damage.
Regular inspection and maintenance are essential. Check the diaphragm for signs of wear, cracking, or deformation, and replace it immediately if any damage is detected. Clean the valve components to prevent buildup of dust or debris that could impair function.
In case of operational issues such as reduced pulse force or air leakage, verify the integrity of the diaphragm and the sealing surfaces. Ensure that the air supply pressure and pulse duration settings are within the recommended ranges.
We recommend using genuine replacement diaphragms and parts to maintain product performance and warranty coverage. Detailed service manuals and technical documentation are available to assist with installation and maintenance procedures.
