PAX1112-03: Exquisite & Corrosion-Resistant, Self-Priming with Ease! Empower Low-Flow Fluid Transfer with this Mini Pneumatic Diaphragm Pump

In applications requiring the transfer of low-flow, sensitive, or corrosive fluids—such as laboratories, medical devices, and analytical instruments—traditional pumps often face challenges like large size, risk of contamination, and potential leakage. The PAX1112-03 is a miniature pneumatic double-diaphragm pump that serves as an ideal solution for precise, low-flow fluid handling. It excels with its compact design, strong self-priming capability, leak-free operation, and excellent corrosion resistance.Core Product Advantages

• Compact, Miniature DesignExtremely small and lightweight structure, making it perfect for integration into space-constrained equipment like analytical instruments and portable devices.
• Powerful Self-Priming, Dry-Run SafeSelf-priming height reaches several meters without needing initial priming. The absence of mechanical seals allows for dry running without pump damage, ideal for emptying containers.
• Leak-Free SealingUtilizes pneumatic actuation with complete isolation between the fluid chamber and the air drive chamber. The seal-less design eliminates any risk of leakage, ensuring safe fluid transfer.
• Compatible with Corrosion-Resistant MaterialsWetted components (diaphragms, ball valves, pump body) offer material options like Polypropylene (PP), Polyvinylidene Fluoride (PVDF), and Teflon (PTFE), providing resistance to various acids, alkalis, organic solvents, and other corrosive liquids.
• Adjustable Flow, Minimal PulsationOutput flow can be infinitely adjusted by regulating the inlet air pressure or flow rate. The reciprocating action of the dual diaphragms results in low outlet pulsation and smooth flow.

Typical Application Scenarios

• Laboratory Equipment:​ Precurse reagent transfer and sampling for chemical analyzers, autosamplers, and dilution instruments.
• Medical Devices:​ Quantitative transfer of medicinal liquids and samples in in-vitro diagnostic analyzers and anesthesia machines.
• Compact Environmental Protection Equipment:​ Reagent addition and sampling for online water quality monitors.
• Semiconductor Industry:​ Micro-volume transfer of high-purity chemicals.

Technical Parameters (Typical Values)

• Port Size:​ Φ6mm Barbed Connector (03 may indicate port code)
• Max Flow Rate:​ Approx. 1-3 L/min (Depends on air pressure and media viscosity)
• Max Pressure:​ 0.7 MPa
• Self-Priming Height:​ 3 meters (water)
• Operating Temperature Range:​ -10℃ ~ +80℃ (Depends on diaphragm material)

SummaryThe PAX1112-03 miniature diaphragm pump is a “mini workhorse” for low-flow, precise fluid transfer. Its small size, leak-free design, and superior corrosion resistance solve the challenges of safely handling micro-volume, high-purity, or corrosive fluids within precision equipment.Choosing the PAX1112-03 means equipping your precision device with a compact, safe, and reliable core component for micro-fluidic transfer!
