PTFE EPDM Metering Pump Diaphragm Rigidity of Material High Strength
Quick details:
| Product Material | PTFE+EPDM |
| Service Life | ≥1000000 times |
| Size | DN8-DN200 |
| Use Scenario | Pharmaceutical, food, chemical |
Features: rigidity, strength, compression, compensation
Metering pump diaphragm performance:
100% pure PTFE sealing surface, providing a clean pollution-free sealing surface.
A unique composite process which firmly sticks PTFE to the rubber elastomer, preventing delamination and leakage.
They're the choice in the electronics industry, chemical plants, and pharmaceutical factories.
Resistant to chemical media other than acid-base metals and elemental fluorine.
Good rigidity, strength and compression, resilience, compensation performance, which can meet high pressure and harsh conditions.
Material:
1 PTFE is suitable for low and high temperature environment
Poly Tetra Fluoro Ethylene (PTFE) is a fluoropolymer synthesized from Ethylene fluoride, which is a kind of fluoroplastic. The chemical inertia of PTFE can prevent cross-linking, so there is no "memory", that is, can not be restored to its original shape as elastomer, the material under tension will produce creep and deformation, the so-called "cold flow" phenomenon. PTFE has a wide range of temperature application (-200~260℃), with good extrusion resistance, corrosion resistance, no aging problem, water and ultraviolet resistance, no toxicity and other characteristics. When the temperature is above 130℃, the simple PTFE diaphragm will produce large deformation, resulting in deformation and damage of the diaphragm.
2 EPDM/ PTFE composite diaphragm is widely used in water for injection or pure steam and other high temperature sanitary conditions
It has both the high elasticity of EPDM and the corrosion resistance of PTFE. In the biological and pharmaceutical industry, only EPDM and PTFE (TFMTM) are available. At present, only these two materials meet the FDA certification and meet the various needs of this industry. TFMTM is the second generation of improved PTFE, which has better diffusion than the traditional PTFE. And has been as a standard for some manufacturers.
The diaphragm is in direct contact with the working medium, and specific analysis should be made for each application before selecting the diaphragm material. Different working conditions often exist in the operation of the same equipment, which leads to the need to use different types of diaphragm materials. The chemical properties and temperature of the medium can cause different interactions, and the suitability of the product used must be checked by product compatibility list or quality order inspection. Only through this procedure can the equipment operate safely, economically and long-standing.
