Product Description:
The ProMinent pump diaphragms are premium replacement membranes specifically engineered for use with ProMinent metering and dosing pumps. These include various series such as the VAMD (Vario D) motor-driven pumps, the MTMDH (Meta) mechanical diaphragm pumps, and the Beta/Concept solenoid-driven models. Crafted from high-quality materials like pure PTFE and a PTFE+EPDM composite, these diaphragms ensure outstanding chemical resistance, extended service life, and dependable sealing performance in rigorous industrial dosing environments.
Featured within ProMinent's product range, the DEVELOPAN® pump diaphragms boast a fabric-reinforced EPDM core paired with a large-area vulcanised steel core. The side that contacts the media is coated with PTFE Teflon, enhancing both durability and chemical protection. The combination of PTFE’s chemical inertness and EPDM’s flexibility in the PTFE+EPDM composite diaphragms makes them especially well-suited for metering fluids containing microcrystals, such as silicate. Meanwhile, diaphragms made entirely of PTFE provide almost universal chemical compatibility with a wide range of aggressive substances.
Whether utilized as original equipment manufacturer (OEM) replacements or for regular maintenance, ProMinent pump diaphragms offer the precision, reliability, and longevity necessary for critical chemical dosing and fluid handling operations. The hermetically sealed metering units, combined with their resistant construction materials, allow these pumps to manage aggressive media efficiently and safely.
