Clean Room and Warm Room

The design team’s ideas for the plant included a “warm room”, where raw liquids that require a higher ambient temperature would be stored, and a “clean room”, where Emco can blend and package food-and pharmaceutical-grade products. For these areas, Cervantes recommended various models of air-operated double-diaphragm (AODD) pumps from Wilden Pump & Engineering.

Emco’s decision to construct a clean room will better position the company as a hygienic manufacturer when expected modifications to US Pharmacopeial Convention (USP) and US Food & Drug Administration (FDA) regulations come into effect in 2015. Emco is using two Wilden Hygienic Series (HS) AODD models in the clean room. “We decided to build the clean room to ISO certification standards,” says Korman. “Not many manufacturers even have a true clean room right now. When the new rules arrive we will be positioned where no one else will have what we have, and the Wilden pumps meet our needs perfectly.”

The warm room, meanwhile, features 17 storage tanks containing a range of chemicals, some hazardous and some very viscous. These are loaded and unloaded with Wilden Advanced Fit Series AODD pumps. Serdar designed the layout of the warm room and chose the equipment. After originally choosing clamped AODD pumps, he determined that a higher level of product containment was needed. He therefore upgraded to 2-inch bolted stainless steel PS800 Advanced Fit Series models. Wilden has designed these to drop into existing AODD pump piping configurations.

The Advanced AODD pumps feature Wilden’s innovative new Pro-Flo Shift air distribution system (ADS), which deliver as much as 60 % savings in air consumption compared to competitive brands (see box). They also offer higher flowrates and higher pumping efficiency. The optimized fluid path of the Fit pumps reduces pressure drop, allowing the pump to produce higher flowrates for the same energy consumption.

“We wanted better product containment and the Pro-Flo Shift Advanced Fit Series pump has been a fool-proof pump that has given us great performance with no worries,” says Serdar. “We chose these pumps because we wanted an economical fit for this application and they were the most cost-effective because of the energy savings.”
