Product Description:
The ProMinent pump diaphragms are premium replacement membranes specifically crafted for use with ProMinent metering and dosing pumps. These include various models such as the VAMD (Vario D) motor-driven series, the MTMDH (Meta) mechanical diaphragm series, and the Beta/Concept solenoid-driven series. Manufactured from high-grade materials, including pure PTFE and a PTFE+EPDM composite, these diaphragms provide outstanding chemical resistance, extended operational life, and reliable sealing performance for challenging industrial dosing environments.
The DEVELOPAN® pump diaphragms from ProMinent are designed with a fabric-reinforced EPDM core, featuring a large-area vulcanised steel core and a PTFE Teflon coating on the surfaces in contact with the media. This construction grants remarkable durability and excellent chemical protection. The PTFE+EPDM composite diaphragms combine the inert chemical properties of PTFE with the flexibility and sealing capabilities of EPDM. This makes them especially well-suited for metering media that contain microcrystals, such as silicate. On the other hand, the PTFE diaphragms boast almost universal chemical compatibility, effectively handling most aggressive chemicals.
Whether applied as original equipment manufacturer (OEM) replacements or utilized during routine maintenance, ProMinent pump diaphragms deliver the precision, dependability, and durability essential for critical chemical dosing and fluid handling tasks. Their hermetically sealed metering units and chemically resistant materials empower these pumps to efficiently manage aggressive media with confidence and ease.
Features:
Premium Material Options
Our diaphragms are available in a variety of premium materials including pure PTFE, PTFE combined with EPDM composite, as well as DEVELOPAN®. The DEVELOPAN® option consists of EPDM with a woven inner layer, a steel core, and a PTFE coating, providing a range of choices to meet different chemical compatibility needs.
ADVANCED DEVELOPAN® Technology
The DEVELOPAN® diaphragms utilize fabric-reinforced EPDM integrated with a large vulcanised steel core. The wetted side is coated with PTFE Teflon, delivering exceptional durability and outstanding chemical resistance. This advanced construction ensures long-lasting performance under demanding conditions.
Pure PTFE Diaphragms
Pure PTFE diaphragms offer nearly universal chemical compatibility, making them ideal for handling the most aggressive and corrosive media. Their robust nature ensures reliable operation when working with highly corrosive substances.
PTFE+EPDM Composite Diaphragms
Combining the chemical inertness of PTFE with the flexibility of EPDM, these composite diaphragms are especially suitable for metering media that contain microcrystalline particles such as silicates. This blend enhances both durability and adaptability.
