Wilden plastic pumps

Wilden air-operated double diaphragm (AODD) pumps with plastic bodies are an excellent solution when chemical resistance, light weight, and versatility are required for demanding industrial liquid transfer applications. Plastic constructions (PP, PVDF, PTFE), combined with Wilden’s advanced air motor technology, provide outstanding chemical compatibility and safety, especially for aggressive fluids.

Why Choose a Wilden Plastic Pump?

• Energy Efficiency as Standard: ProFlo® SHIFT air distribution system (ADS) reduces air consumption by up to 60% without compromising flow performance.
• Durable Materials: Polypropylene, PVDF, PTFE – broad chemical compatibility and excellent corrosion resistance.
• Lightweight and Easily Portable: Plastic pumps are lighter than metal ones, making installation and relocation easier.
• Bolted Advanced™ Series Construction: Minimizes leakage risks and ensures complete product containment.
• Wide Range of Elastomers: PTFE, EPDM, FKM WilFlex™, Saniflex® – choose according to your process needs.
• Process-Safe, Versatile Dry-Run and Self-Priming Capability.
