Positive Displacement Pumps for Dairy

Our precision-engineered positive displacement pumps suit the needs of any dairy application and help you fight downtime for optimal efficiency.

Dairy processing involves a variety of materials and consistencies – from smooth, rich ice creams to all styles of cheeses, yogurts and more. In all types of dairy processing, you need positive displacement (PD) pumps that can handle a range of viscosities and pressures. Your dairy pumps should be easily reassembled after cleaning out of place (COP) to keep your production downtime minimum. No matter the product, successful processing requires a pump with low shear and consistent throughput.

Your processing demands are unique, which is why our innovative PD lobe and gear pumps are precision-engineered in all stainless steel (which inspectors love) and feature a compact design that delivers smooth, low-shear performance while maintaining product integrity. Our PD pump solutions have been proven to simplify dairy processing without sacrificing the quality of any dairy product.

An example is yogurt applications in which they need to transfer flavors (such as strawberry or blueberry) out of drums. Often the drums have a hygienic liner that can be a challenge for a traditional pump (it will suck the product and bag into the pump). However, a UHT Standard pump product offers a special BagLiner series pump for this exact application.

Features and Benefits

Our sanitary pumps excel in the dairy industry and provide many benefits:

  • Flat, crevice-free front cover that eliminates product dead zones
  • CIP and COP capability
  • Compact design
  • Horizontal or vertical mounting versatility
  • Elimination of pump and motor alignment issues
  • Safe design with no accessible moving parts
  • Easy maintenance
  • Diaphragm rupture detection systems
