Product Description:
This extensive selection of replacement diaphragms is meticulously designed to fit Milton Roy’s mechanical and hydraulic diaphragm metering pumps. It accommodates popular models such as the GM series (ranging from GM0002 to GM1200), the GB series (from GB0350 to GB1800), and the mRoy MRA/MRB product lines.
Crafted from premium materials like virgin PTFE and F46 fluoropolymer, these diaphragms deliver outstanding chemical resistance, exceptional flexibility, and dependable sealing performance. They are specifically built to endure the rigorous demands of dosing applications, ensuring longevity and consistent functionality.
The GM and GB series are equipped with 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 models incorporate hydraulically balanced PTFE diaphragms engineered for an impressive operational lifespan of up to 96,000 hours.
Whether you require a single diaphragm for an emergency repair or a comprehensive service kit for preventative maintenance, this range offers OEM-quality replacements. These parts help restore pump performance and reduce downtime across various sectors, including water treatment, chemical processing, and industrial dosing.
Features:
Broad Compatibility
These components are designed to be broadly compatible with a range of Milton Roy models. They fit the GM series (from GM0002 to GM1200), the GB series (ranging from GB0350 to GB1800), as well as the mRoy MRA and MRB models, ensuring versatile application across multiple pump types.
Premium Materials
Constructed from high-quality materials, these diaphragms offer excellent performance and durability. Virgin PTFE is used for its maximum chemical inertness, FDA compliance, outstanding non-stick characteristics, and the ability to withstand temperatures up to +150°C.
Additionally, F46 fluoropolymer provides superior chemical resistance and enhanced flexibility compared to standard PTFE, making it ideal for demanding environments.
Innovative Designs
The mechanically actuated design, used in the GM and GB series, features a robust PTFE diaphragm ensuring reliable and consistent dosing. Meanwhile, the hydraulically balanced design found in the mRoy MRA and MRB models uses a PTFE diaphragm with an extended operating life of up to 96,000 hours. This design eliminates the need for seal and plunger packing maintenance, improving longevity and reducing downtime.
Precision Engineering and Assembly
Each diaphragm is precision molded to guarantee an accurate fit and effective sealing against pump heads. The components come either as integral studs or assemblies, which include the diaphragm plate, O-ring, and screw where applicable, providing a complete replacement solution.
For easy identification, the diaphragms are color-coded in white or off-white when made from PTFE. They are available as single diaphragms or full service kits that contain O-rings, gaskets, and seals to support maintenance needs.
Durability and Application Suitability
Designed for a long service life, these diaphragms can endure millions of cycles under continuous duty conditions. Their material composition and construction make them well-suited for use with aggressive chemicals, as well as in high-purity and sanitary applications where PTFE's properties are essential.
