1 Inch PP AODD Pump - Chemical Resistant Air Diaphragm Pump

1 Inch PP AODD Pump - Chemical Resistant Air Diaphragm Pump

The NOVAPUMP 1 Inch PP (Polypropylene) AODD Pump is the ultimate solution for aggressive chemical transfer where metal pumps corrode and fail. With its full polypropylene fluid body and PTFE diaphragms, this air-operated pump handles nearly any acid, alkali, or solvent without degradation. Ideal for chemical processing plants, electroplating lines, and wastewater treatment facilities.

Key Features

• Full Chemical Resistance: PP body + PTFE diaphragms + PTFE balls = handles 98% of industrial chemicals
• No Electrical Components: 100% air-operated - intrinsically safe for explosive atmospheres (ATEX zones)
• Self-Priming to 5m: Automatically evacuates air from suction line without manual priming
• Stall-Free Design: Patented air valve design eliminates mid-cycle stalling common in other AODD pumps
• Lightweight: At 8.5 kg, the PP body is 60% lighter than equivalent metal pumps

Applications

Acid transfer (H2SO4, HCl, HNO3 up to 98%), alkali transfer (NaOH, KOH), electroplating solution circulation, wastewater chemical dosing, solvent transfer, and bleach/pool chemical pumping.

FAQs

Q: What chemicals can it NOT handle?
Concentrated nitric acid above 60%, fuming sulfuric acid (oleum), liquid bromine, and strong oxidizing agents at elevated temperatures. Contact our engineering team for a chemical compatibility matrix.

Q: Is it suitable for food-grade applications?
No, the standard PP/EPDM configuration is for industrial use only. Food-grade (FDA PP body, Santoprene/PTFE diaphragm) available on special order.

Q: What spare parts should I stock?
We recommend 2 sets of diaphragms and 1 set of ball valves per pump for one year of continuous operation.
