Waukesha MDL Sanitary Pump Series is specified for medium-duty sanitary transfer of viscous, non-abrasive and shear-sensitive fluids in food, beverage and pharmaceutical processing. It is relevant where gentle product handling, cleanability and predictable maintenance affect product quality and production continuity. AxFlow can help assess whether the selected MDL size fits the actual duty point, process media and cleaning requirements.
The series uses a sanitary rotary lobe positive displacement principle with stainless steel 316L rotors and a tri-lobe configuration. Source material confirms CIP suitability and mechanical seal options, including single and double arrangements depending on configuration. Selection should consider flow, differential pressure, temperature, viscosity, media compatibility, connection type and seal arrangement.
Verified AxFlow source data states nine MDL models with capacities up to 124 m3/h and differential pressure up to 10 bar. The series was developed for medium-duty sanitary applications and gentle handling of viscous, non-abrasive and shear-sensitive fluids. Exact temperature, viscosity, elastomer and connection limits should be confirmed for the selected model before specification.
For maintenance and total cost of ownership, correct sizing and seal selection help reduce avoidable wear and unplanned downtime. A defined spare-parts strategy also gives maintenance teams a clearer basis for planned service. AxFlow can support model selection, availability checks, service planning and spare-parts identification.
