This component is used in the following industrial products
A precision fluid handling component designed to accurately measure and dispense specific volumes of liquid ingredients within an automated beverage blending system.
A pump designed to deliver precise volumes of beverage syrup or concentrate with high accuracy and repeatability.
A valve that automatically reduces a higher inlet pressure to a steady lower outlet pressure regardless of flow variations.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Diaphragm / Piston.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Diaphragms use a flexible membrane to isolate fluid from the drive, ideal for corrosive or sterile applications, while pistons are rigid plungers for high-pressure or viscous fluids, offering direct displacement but requiring robust sealing.
Choose based on fluid compatibility, pressure, temperature, and hygiene requirements. For example, PTFE for chemical resistance, stainless steel for durability, and elastomers for flexibility in sanitary applications.
