Product Description:
This extensive selection of replacement diaphragms is expertly designed 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 from GB0350 to GB1800, as well as the mRoy MRA and MRB variants.
Constructed from premium materials such as virgin PTFE and F46 fluoropolymer, these diaphragms deliver outstanding chemical resistance, extended flex life, and dependable sealing performance. These qualities make them ideal for challenging dosing environments where reliability is crucial.
Specifically, the GM and GB series comprise 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 that are engineered to provide an impressive operating lifespan of up to 96,000 hours.
Whether you require a single diaphragm for urgent repairs or a complete service kit for scheduled maintenance, this product range offers OEM-quality replacement components. They help ensure pumps maintain peak efficiency and reduce downtime across various applications, including water treatment, chemical processing, and industrial dosing systems.
Features:
This product offers broad compatibility, making it suitable for a variety of Milton Roy pump models. It fits the GM series ranging from GM0002 to GM1200, the GB series from GB0350 to GB1800, as well as the mRoy MRA and MRB models.
Constructed from premium materials, the diaphragms feature virgin PTFE, which provides maximum chemical inertness. This FDA-compliant material boasts excellent non-stick properties and can withstand temperatures up to +150°C. Additionally, the use of F46 fluoropolymer offers superior chemical resistance with improved flexibility compared to standard PTFE.
The GM and GB series utilize a mechanically actuated design with a robust PTFE diaphragm that ensures reliable dosing performance. In contrast, the mRoy MRA and MRB models employ a hydraulically balanced design with a PTFE diaphragm engineered for an extended operating life of up to 96,000 hours, effectively eliminating the need for seal and plunger packing maintenance.
Each diaphragm is precision molded to guarantee an accurate fit and proper sealing against the pump heads. The assembly often includes integral components such as the diaphragm plate, O-ring, and screw as required, providing a complete replacement solution.
For easy identification, the diaphragms are color-coded in white or off-white, which corresponds to PTFE material. They are available both as single diaphragms and in full service kits that contain O-rings, gaskets, and seals.
Designed for long service life, these diaphragms are engineered to handle millions of cycles under continuous duty. They are well suited for use with aggressive chemicals, high-purity environments, and sanitary applications where PTFE’s properties are particularly beneficial.

Support and Services:
Our Pulse Valve Diaphragms are designed to deliver reliable performance and long service life in demanding industrial applications. To ensure optimal functionality, it is important to follow proper installation, maintenance, and troubleshooting procedures.
Installation: Before installing the diaphragm, ensure that the valve is clean and free from debris. Align the diaphragm correctly according to the manufacturer's specifications to prevent leaks and ensure proper sealing. Avoid using excessive force during installation to prevent damage.
Maintenance: Regular inspection of the diaphragm is recommended to detect signs of wear, cracks, or deformation. Replace the diaphragm immediately if any damage is observed to maintain system efficiency. Use only genuine replacement parts to ensure compatibility and performance.
Troubleshooting: Common issues such as air leaks, reduced pulse efficiency, or valve malfunction may be related to diaphragm condition. Check for proper seating, integrity, and cleanliness of the diaphragm. Cleaning with a mild solvent may help remove deposits, but avoid harsh chemicals that could degrade the material.
Storage: Store diaphragms in a cool, dry place away from direct sunlight and ozone sources. Keep them in their original packaging until ready for use to prevent contamination and damage.
