You can experience leaks, loss of flow, unplanned downtime, lost revenue, safety risks for your employees and even environmental issues if fluid escapes the designated areas around your lines. To achieve and maintain hygienic conditions and prevent contamination, the food and beverage industry employs a wide range of pumps for various processing applications.
Pumps are some of the most important pieces of equipment in food and beverage processing. Along with having to handle both low- and high-viscosity fluids, pumps used in the food and beverage industry must provide solutions to these processing challenges:
Air-operated double diaphragm (AODD) pumps are known for reliability, safety and simplicity in fluids, slurries and solids-laden transfers, making this type of pump ideal for food and beverage processing. AODD pumps:
Because pumps are crucial to keeping your food and beverage processing systems running properly, it’s important that you select the type that best meets your needs. Regardless of whether a pump is a food-grade air diaphragm pump or a centrifugal pump, for food and beverage applications, it must:
The materials that make up a pump are key to ensuring the pump is FDA-compliant. Because the FDA regulates many food products, all pump components must comply with the FDA’s Code of Federal Regulations (CFR) Title 21 Part 177 for materials that come in contact with food and beverages. Santoprene, Polytetrafluoroethylene or Teflon (PTFE) and stainless steel are several popular options for FDA-compliant food processing AODD pumps. For a superior surface finish, some manufacturers offer additional mechanically polished and electropolished stainless steel materials.
When pumping costly fluids like those used in the food and beverage industry (i.e., sauces, oils, beer, wine), leak detection products are beneficial because they allow you to monitor your pump’s diaphragm integrity through visual, electronic or mechanical leak detection systems.
AODD pumps used in Food and Beverage applications are constructed by either clamping or bolting the mating parts together. If your food and beverage processing pumps are part of a batch process like salsa or barbeque sauce requiring regular and frequent equipment tear-downs for cleaning and sanitation, then clamped construction pumps are ideal as it typically takes less time to take apart, clean, and re-build. If your process takes much longer and equipment is not torn frequently such as a winery fermentation and pump-over process, then bolted pumps may be more ideal as bolted construction pumps are generally more robust and leak-tight over a long period of time.
Most AODD pumps have discharge ports on top of the pump so any fluids containing settling solids struggle to pass through and can remain stuck inside. Bottom discharge porting can help eliminate damage and frequent maintenance caused by solids settling in your pump as gravity assists with helping the fluid pass through. Other porting options or check valve types may provide you with improved suction lift. When choosing an AODD pump manufacturer, choose one that has experienced application engineers on staff to help you determine the best pump size and porting configuration for your application. Not only will this increase your pump’s performance life and efficiency, but it’ll also save you time and money.
Now that you know which features pumps must have for food and beverage applications, find the right pump for your project. Whether your application includes food filling and packaging, product batching and transfer, recirculation and fermentation pump-overs, SANDPIPER’s food-grade AODD pumps are here to help.
