- Understand the amount of water used in pump seals within food processing and how to use water recycling technology to reduce water use.
This resource covers how pump seal wastewater can be reused for washing crates and pallets. In addition, water efficiency can be increased by creating a closed-loop pump seal water system.
Pump seals in food processing can use significant amounts of potable water. Pump seals are required in animal processing, animal food, bakeries, beverage production, dairy products, fruits and vegetables, grains, oils, seeds, seafood, and sugar manufacturing. In all pipe systems, pumps move the product to its destination. Food service pumps must be made of food grade materials and may not use lubricants or materials that could contaminate the food being processed. The seals on the pump must also keep out contaminants. As a result, water seals are commonly used. With water seals, if the seal leaks only clean potable water will enter the food. However, water seals on pumps continuously discharge water. With multiple pumps in a typical food processing plants, pump seal water use can be significant.
