Waukesha ZM Technologies 520 High Capacity Positive Displacement Pump

The Waukesha ZM Technologies Model 520 is a high-capacity positive displacement pump designed for sanitary and industrial applications, particularly in food, beverage, pharmaceutical, and chemical processing industries. This rotary piston pump excels in handling viscous fluids, shear-sensitive materials, and high-volume transfers with minimal pulsation. Key features include a robust stainless steel construction for corrosion resistance, CIP (Clean-In-Place) capabilities for easy maintenance, and bi-directional operation for versatile installation. It offers advantages over centrifugal pumps by providing consistent flow rates regardless of pressure changes, reducing product damage, and enabling precise metering. Benefits include high efficiency, low maintenance costs, and compliance with 3-A sanitary standards. Drawbacks may include higher initial cost and the need for regular seal inspections in abrasive environments. This model is ideal for transferring creams, gels, slurries, and other thick media, with superior performance in high-pressure scenarios compared to similar lobe or gear pumps. Based on attached images, the unit appears used with minor surface wear and rust spots but no major damage, suggesting good operational condition after potential refurbishment. Serial number 180420.19 indicates possible 2019 manufacture. No parent/child assets visible, but it includes flanged ports and a shaft for motor coupling.
