Description
Wilden 00-5411-16 Air Operated Double Diaphragm AODD Pump 1/4 NPT Polypropylene
The Wilden 00-5411-16 is a compact air operated double diaphragm (AODD) pump with a polypropylene body. It uses compressed air as its motive force to flex two diaphragms alternately, drawing fluid in on one side while discharging on the other — with no need for electricity and no dynamic shaft seals in contact with the pumped fluid. This is a small-format AODD pump suited for low-flow transfer of thin to moderately viscous fluids, chemicals, and liquids in laboratory or light industrial settings.

Applications
Wilden is one of the original and most widely recognized manufacturers of air operated double diaphragm pumps, and their compact mini-series pumps like this 00-5411-16 are used throughout laboratory, chemical processing, pharmaceutical, and light industrial environments for transferring liquids that may be corrosive, abrasive, shear-sensitive, or hazardous. Because AODD pumps are self-priming, can run dry without damage, and handle solids in suspension, they are a common choice for drum unloading, reagent transfer, sampling, and waste collection. The polypropylene construction makes this pump suitable for many mild acids, bases, and solvents. The small 1/4 NPT port size is typical for bench-scale or low-flow process work. These pumps have been a staple in chemical and process labs since the 1980s and remain in active use today across a wide range of fluid handling applications.
This Wilden 00-5411-16 Air Operated Double Diaphragm Pump is in used condition, pulled from a working environment where it was previously in service. The polypropylene body shows general surface soiling and typical handling wear consistent with industrial use. The stainless steel clamp bands and center air section appear intact, with the blue pilot spool visible and undamaged. Port caps are present on both top discharge outlets. No cracks or structural damage are visible. Please review our photos carefully and contact us with any questions before purchasing.
