Wilden Donates Pump to Fresno State University Lab

12 March 2020

Wilden®, part of PSG®, a Dover company, 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 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.

“We use the pump to produce the majority of our jarred products,” explained Carmen Licon, Assistant Professor for Fresno State’s Department of Food Science and Nutrition. “Last semester, our old diaphragm pump broke down, so we needed to find a new one.”

The pump has been specially designed to meet all of the needs of a food-manufacturing operation. Wilden 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.
