PTFE Diaphragm Pumps

PTFE Diaphragm Pumps

PTFE diaphragm pumps are made with polytetrafluoroethylene, a material known for strong chemical resistance and good temperature resistance. They are used for aggressive liquids that may not be compatible with standard plastic pump materials, especially in chemical processing, electronic circuit production, pharmaceutical processes, and other demanding applications.

Advantages
Safe and Stable Operation
  • Air-Driven Operation for Hazardous Areas: PTFE air-operated diaphragm pumps run on compressed air, with no electrical components at the pump body and no electric sparks during operation, so they are suitable for areas with explosion risks.
  • Full PTFE Material for Aggressive Chemicals: The full PTFE structure is suitable for strong acids, strong alkalis, and other highly corrosive liquids that require stronger material compatibility.
  • Better Protection for Fasteners: Fluorine-lined bolts are covered by PTFE plugs, which protects them from direct exposure in harsh chemical environments.
  • Easier Assembly and Maintenance: The upper and lower covers share the same design, so assembly is simpler and maintenance work is easier.
  • Longer Diaphragm Service Life: The integrated composite diaphragm supports continuous operation for more than 2000 hours under suitable working conditions.
  • Higher machining accuracy: CNC-machined parts fit more precisely than typical injection-molded parts, which supports better sealing performance.
Practical Structural Design
  • Strong Pump Chamber: The chamber has a solid structure, and the streamlined flow path reduces resistance during liquid transfer.
  • One-Piece Intermediate Section: The integrated intermediate structure provides better strength and stable support for the pump body.
  • Integrated Composite Diaphragm: The one-piece composite diaphragm improves durability during repeated movement and supports longer service life.
  • Durable Ball Valve Assembly: Strong valve balls, cage-style valve seats, and linear sealing surfaces help the valves open, close, and seal more reliably.
  • Integrated Inlet and Outlet Ports: The inlet and outlet structure have good strength and is easier to disassemble. Different port directions are available to make installation and pipeline layout more flexible.
Applications

PTFE diaphragm pumps are a strong option for aggressive chemicals, high-purity liquids, and fluids that require clean material compatibility. Common applications include:

  • Chemical Processing: Strong acids such as sulfuric acid, hydrochloric acid, and nitric acid, as well as strong alkalis and other highly corrosive chemicals.
  • Food and Beverage: Fruit juice, milk, syrup, and other liquid food materials that require compatible pump materials and proper hygiene configuration.
  • Pharmaceutical Production: Corrosive pharmaceutical liquids and high-purity raw materials used in production or transfer processes.
  • Electronics Industry: Electroplating solutions and chemical reagents used in electronic components, circuit boards, and related processes.
  • Environmental Treatment: Wastewater with suspended solids, solid particles, or corrosive chemical additives.
