Product Description:
The ProMinent pump diaphragms are premium replacement membranes specifically engineered for use in ProMinent metering and dosing pumps. They cover a range of pump types including the VAMD (Vario D) motor-driven series, the MTMDH (Meta) mechanical diaphragm series, and the Beta/Concept solenoid-driven series. Crafted from high-quality materials such as pure PTFE and PTFE+EPDM composites, these diaphragms provide outstanding chemical resistance, extended service life, and dependable sealing performance, making them ideal for challenging industrial dosing environments.
Among the product line, ProMinent's DEVELOPAN® pump diaphragms stand out with their fabric-reinforced EPDM core, complemented by a large-area vulcanized steel core and a PTFE Teflon coating on the surface that contacts the media. This unique construction ensures exceptional strength, durability, and chemical protection. The PTFE+EPDM composite diaphragms merge the chemical inertness of PTFE with the flexibility and sealing efficiency of EPDM, which makes them especially effective when handling metering media containing microcrystals like silicate. Furthermore, the PTFE diaphragms exhibit nearly universal chemical compatibility with a broad spectrum of aggressive substances.
Whether utilized as original equipment manufacturer (OEM) parts or for regular maintenance tasks, ProMinent pump diaphragms consistently provide the accuracy, reliability, and durability that are critical in chemical dosing and fluid handling operations. Their hermetically sealed metering units, together with corrosion-resistant materials, allow these pumps to efficiently manage aggressive media without compromising performance.
