Containment and Efficiency

Wilden’s Advanced Series metal and plastic bolted AODD pumps are designed for maximum performance, efficiency and containment. The bolted configuration ensures product containment, while the absence of a mechanical seal or packing reduces the risk of leaks and pump failure. A “drop in” design allows the pump to be installed into an existing pump footprint without the need to disturb the piping, resulting in reduced maintenance costs and system downtime.

Another containment feature is Wilden’s integral piston diaphragm. Most AODD pumps offer multiple-piece diaphragm configurations, but Wilden’s integral piston diaphragms are made in a single piece, eliminating any potential leak points. Full-stroke PTFE diaphragms provide increased product displacement per stroke, resulting in greater flowrates and higher efficiencies compared to pumps that rely on reduced-stroke PTFE diaphragms.

The patented Pro-Flo X ADS allows the operator to dial in the actual operating conditions regardless of the pump size. Because it uses the minimum amount of compressed air necessary for the job in hand, this results in pump operation that is the most efficient and cost-effective in the industry.
