The various models of Wilden® bolted AODD pumps offer many operational advantages for chemical processors, including optimized flow paths, easy maintenance, quick assembly and disassembly, and the ability to be a bolt-to-bolt and pipe-to-pipe drop-in replacement for competitive pump models.
3) Versatile and Compatible
AODD pumps can also match the supposed benefits of competing pump technologies in chemical processing because they have a number of operational advantages:
- Can be used with fluids from water-like to high-viscosity
- Can run dry and strip discharge lines without getting damaged
- Control relies solely on solenoid operators, pump-cycle counters and surge-dampener assemblies
- Operating costs are lower when all maintenance, accessories and controllers are considered
Also, a new generation of AODD pump styles – highlighted by Wilden’s bolted pump models – have been designed to be direct bolt-to-bolt and pipe-to-pipe drop-in replacements in existing pumping systems. Finally, the operation of AODD pumps virtually eliminates product slip since the pump’s ball check valves control fluid transfer.
4) Pump Construction
AODD pumps are available in a wide range of materials of construction. Common chemical-pump materials include polypropylene, Kynar®, stainless steel, ductile iron and Hastelloy, with some companies, like Wilden, able to offer special materials like super duplex when really unique materials are required.
If metal pumps are required, one overlooked material is ductile iron, which works well in both acidic and basic PH application ranges of 4 to 10. Provided that the chemical compatibility is correct, operators who use ductile-iron pumps can realize all of the benefits of stainless steel, but at a lower price point.
Conclusion
The design and operation of the AODD pump has proven to be able to meet the demands of chemical processors. The AODD pump, which possesses a stable of notable operational characteristics, has become a first-choice technology for chemical manufacturers who are searching for a pump that meshes cost-conscious air consumption with reliable and safe production rates.
