1/4 Inch Mini AODD Pump - Micro Air Diaphragm Pump for Sampling & Lab

1/4 Inch Mini AODD Pump - Micro Air Diaphragm Pump for Sampling & Dosing

The NOVAPUMP 1/4 Inch Mini AODD Pump is our smallest diaphragm pump, designed for precision micro-flow applications where accuracy and chemical compatibility matter more than volume. With a flow range of 0.5-15 L/min and the ability to handle viscosities up to 5,000 cP at low flow rates, this pump excels in chemical dosing, laboratory sampling, inkjet supply, and medical device fluid handling.

Technical Specifications

• Size: 1/4 inch inlet/outlet (threaded)
• Max Flow Rate: 15 L/min (4 GPM)
• Max Head: 70 meters (230 ft)
• Air Supply: 1-7 bar (14-101 PSI)
• Air Inlet: 1/8 inch push-connect
• Body Material: Polypropylene or PVDF (select at order)
• Diaphragm: PTFE (standard for chemical compatibility)
• Ball Valves: PTFE or 316 SS
• Weight: 0.9 kg (PP body) / 1.2 kg (PVDF)

Key Features

• Micro-Flow Precision: Delivers as little as 0.5 L/min with proportional air control
• Chemical Compatibility: PVDF body option handles aggressive media; PTFE internals as standard
• Pulse-Free Option: Available with pulsation dampener accessory for smooth flow in sensitive applications
• Bench-Top Portable: Under 1 kg - easily move between workstations or mount in laboratory setups
• No Electrical Power: Operates on compressed air or nitrogen bottle - safe in hazardous areas

Applications

Chemical metering and dosing, laboratory sample transfer, inkjet printer ink supply, medical diagnostic fluid handling, and environmental water sampling pumps.

FAQs

Q: Can it dose precise volumes?
With a cycle counter and solenoid valve on the air inlet, it can dose within ±3% accuracy. Contact us for dosing control kit options.

Q: What is the minimum air pressure needed?
Operates from 1 bar (14 PSI). A small diaphragm air compressor or nitrogen bottle regulator is sufficient.

Q: Is it repairable?
Yes, fully serviceable. The mini diaphragm and ball valve kit costs approximately 25% of pump price.
