This pneumatic polypropylene diaphragm pump is an air-operated double diaphragm pump (AODD) designed for handling corrosive and challenging fluids. With a maximum flow rate of 44L/Min and operating pressure of 6.9bar, it delivers reliable performance in demanding industrial applications.

• Zero leakage design for safe operation
• Excellent self-priming performance
• Compatible with various media types
• Available in multiple materials: Cast steel, Aluminum, Stainless Steel, Polypropylene

• Hazardous liquids: toxic, flammable, and volatile substances
• Corrosive chemicals: strong acids and strong alkalis
• Industrial fluids: paints, adhesives, solvents, and coatings
• Food processing: syrups, chocolate, fruit pulp, and food products
• Construction materials: ceramic slurry, grouting, and mortar
• Oil and petroleum products: tanker unloading and residual oil pumping

The pump utilizes alternating air pressure to create intake and discharge cycles in the fluid chamber. Ball valves ensure unidirectional fluid flow, while the modular air motor and fluid section design provides reliable performance across various operating conditions.

• Remove upper and lower manifold components
• Extract ball valves, O-rings, and ball seats
• Carefully remove fluid cap and diaphragm assemblies
• Use proper tools to avoid damaging diaphragm rod surfaces

• Clean and inspect all components before reassembly
• Replace worn or damaged parts with genuine replacements
• Apply appropriate lubrication to diaphragm rod and seals
• Ensure proper alignment of diaphragms to prevent twisting
• Verify all fasteners and seals after initial operation
