Air-Operated Double Diaphragm Pumps (AODD) How Energy-Saving AODD Pumps Help to Keep Products Flowing
Emco Chemical Distributors relies on Wilden Pro-Flo Shift Advanced Fit Series and Hygienic Series air-operated double diaphragm (AODD) pumps to transfer liquids at its new facility in Pleasant Prairie, Wisconsin/USA. Learn how their innovative air control valves provide big savings in compressed air consumption compared to other types of AODD pump.
After four decades of continuous growth, Emco Chemical Distributors finally ran out of expansion room at its location in North Chicago, USA. In 2010 the company unveiled plans to create a new headquarters and distribution facility at an old resin and ink factory in Pleasant Prairie, Wisconsin, just across the Illinois-Wisconsin border near the city of Kenosha.
The new facility officially opened in August 2013. It is a tribute not only to the vision of founder Edward Polen but also to the abilities of B.J. Korman, Stuart Levy and Mark Serdar, who are, respectively, Emco’s Vice President of Engineering; Vice President, Maintenance; and Facilities Maintenance Manager. That trio was tasked with designing and engineering the layout of the new facility. The vacant building gave them a blank canvas on which to locate the various warehousing, blending, packaging, liquid-storage, test-lab and operations areas.
“When we were finished, we moved our entire industrial-chemical division to Pleasant Prairie,” says Korman. “At heart, we’re a just-in-time distributor. We make a blend, make a tote and get it out to the customer the next day. We can create bulk quantities of chemicals from 11,000 gallons (40 m3), on down to five-gallon (20 l) containers.”
Looking For the Right Pumps
The complexity of the project, specifically identifying the types of pumps that would be needed, forced Korman, Levy and Serdar to expand their team. They did not hesitate to include Joe Cervantes, Pump Sales Engineer for Brookfield, WI-based Anderson Pump & Process, Emco’s long-time pump supplier.
“When Emco wanted to expand, they knew us and came to me to ask my thoughts on what pumping technologies to use,” says Cervantes. “In addition to the main storage and packaging areas, they were planning on adding a couple of unique operations that were better suited to diaphragm-pump technologies. They had been using some old air-diaphragm pumps in the North Chicago plant, but we knew there were newer diaphragm-pump technologies available that could aid in the efficiency of their operations.”
The design team’s ideas for the plant included a “warm room” and a “clean room”. Read more on the next page ...
