Our Omniseal® diaphragms are designed to provide a long lifetime in the harshest environments; therefore, we only use materials that offer an excellent compromise between chemical compatibility and mechanical properties: Virgin PTFE and Modified PTFE materials.
Our Omniseal® diaphragms are molded to the final shape for valves diaphragms or thermoformed (TFM) for the pump diaphragms. In both cases, solutions are designed to fit the customer's hardware to ensure easy assembly and integration. They are designed for both low and high pressures.
Temperature resistance
from -240°C to +280°C (-400°F to +536°F), temperature is dependent on materials selected in design phase of pump or valve diaphragm
Pressure
145 psi (10 bar) maximum for pump & valve diaphragms
Max Speed
High speed & frequency (pump)
Low speed & frequency for closing and opening (valve)
Dimensions Diameter
Pump diaphragms: from 50 mm to 400 mm
Valve diaphragms: Nominal DN8 (¼”) to DN150 (6”)
Fluoroloy® Fluoropolymers
High performance proprietary material formulations
Consisting of a family of proprietary materials that are composed primarily of polytetrafluoroethylene (PTFE) based resins, the different grades of this high-performance polymer material have been specifically formulated to meet the needs of challenging applications and the different applicable certifications. For example, some grades were designed to be USDA, USP, and/or FDA compliant and therefore well suited for life science equipment such as harmonic scalpels or chemical analyzers.
Used in
when low friction or high wear life / abrasion resistance is needed
