Wilden® Donates Saniflo™ FDA Series AODD Pump to Food Processing Laboratory at Fresno State University

Wilden Donates Saniflo

Wilden®, part of PSG®, a Dover company and a worldwide leader in specialty pumps, is proud to announce that it has recently donated a 38 mm (1-1/2”) Pro-Flo® SHIFT Saniflo FDA Series Air-Operated Double-Diaphragm (AODD) Pump with Pure-Fuse Diaphragms to the Food Processing Laboratory at Fresno State University, Fresno, CA. The donated pump, a PS4 model in Wilden nomenclature, will receive hands-on use from the upwards of 80 students who are currently enrolled in Fresno State’s Department of Food Science and Nutrition.

As part of their educational requirements, these students are tasked with producing a wide variety of food products, including jams, jellies, salsas and sauces – all in a processing environment that cannot compromise food quality or safety. The Wilden PS4 pump will play a significant role as the conduit between the manufacturing system’s cooking kettles and filling lines; without it, the students would have to jar their products by hand, a time-consuming and potentially unsanitary process.

During this time, we teach them about food safety and good manufacturing practices. Last semester, our old diaphragm pump broke down, so we needed to find a new one because we didn’t want to have to jar by hand, which is time-consuming and unsafe for students.”

Wilden donated a pump that was specially designed to meet all of the needs of a food-manufacturing operation. The FDA Series pumps possess Tri-Clamp® connections and a straight flow-through design that gives them the versatility to pump shear-sensitive liquids with a wide range of viscosities and solids sizes, including the high-acid, high-sugar and high-fat media that are found in many of the products produced by the Fresno State students. The pumps have passivated stainless steel components with various surface finishes, which allows them to comply with all FDA, CE, 1935/2004/EC and ATEX regulations regarding the sanitary and intrinsically safe production of food products.

The pump’s Pro-Flo SHIFT Air Distribution System (ADS) is the industry’s most efficient as its design automatically restricts the amount of air that enters the pump, eliminating any overcharging of the air chamber with no reduction in flow rate. The result is an AODD pump that delivers up to a 60% reduction in air consumption and 34% more product yield than competitive models. Finally, the pump is outfitted with Pure-Fuse Integral Piston Diaphragms. The design of these diaphragms features an integrated one-piece piston that eliminates the trap areas and abrasion that are common with other diaphragm styles, resulting in a cleaner, more durable pumping process.

“The pump is easy to use and set up; it didn’t cost us a lot of time or effort to figure out how to use it,” said Licon. “For cleaning, we do clean-out-of-place. We basically take it apart, run a cycle with soap and water and it’s ready to be used again. With the older pump, we couldn’t do that, we had to flush a lot of water and soap until the water ran clean. With this new pump, it takes around 20 minutes to clean.”

The Wilden FDA Series pump arrived on campus in October 2019 and immediately went to work. Licon is looking forward to the spring semester and summer internships when it will be used to help produce the products that are featured at Fresno State’s Gibson Farm Market, the on-campus food store where the products that have been grown, processed and packaged by the Fresno State students are sold.

“Overall, I am very happy so far and would definitely recommend the Wilden pump to others,” said Licon. “It’s very easy to use and clean, very user-friendly, just plug it in and it’s ready to go. It’s a good asset for us, a welcome upgrade from what we had before. I love it. Now, I can teach my students how the pump works, they can see inside it and they can see how the diaphragms work. I would really just like to thank Wilden for the donation.”
