Product Description:
The ProMinent pump diaphragms are premium replacement membranes specifically engineered for a range of ProMinent metering and dosing pumps. This encompasses the VAMD (Vario D) series driven by motors, the MTMDH (Meta) mechanical diaphragm series, as well as the Beta/Concept solenoid-driven models. Crafted from high-quality materials such as pure PTFE and a PTFE+EPDM composite, these diaphragms ensure outstanding chemical resistance, extended durability, and dependable sealing performance in challenging industrial dosing environments.
ProMinent's DEVELOPAN® pump diaphragms are constructed with a fabric-reinforced EPDM core, reinforced by a large-area vulcanised steel core, and coated with a PTFE Teflon layer on the surface that contacts the media. This design provides remarkable strength and excellent chemical protection. The PTFE+EPDM composite diaphragms blend the chemical inertness of PTFE with EPDM’s flexibility and sealing abilities, making them especially effective for metering fluids that contain microcrystals such as silicates. Meanwhile, the pure PTFE diaphragms offer near-universal chemical compatibility, performing reliably with most aggressive chemicals.
Whether chosen as original equipment manufacturer (OEM) parts or for regular upkeep, ProMinent pump diaphragms guarantee precision, reliability, and a long operational lifespan. Thanks to their hermetically sealed metering units and chemically resistant materials, these pumps are capable of handling aggressive media effortlessly, ensuring optimal performance in critical chemical dosing and fluid management applications.
