Product description

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.

Waukesha MDL Sanitary Pump Series is intended for gentle transfer of viscous, non-abrasive and shear-sensitive fluids in food, beverage and pharmaceutical processing where CIP is required. It is based on Waukesha Cherry-Burrell medium-duty sanitary rotary lobe pump series technology and should be matched to the actual process duty. AxFlow can support selection and availability checks for the required application.
Waukesha MDL Sanitary Pump Series should be selected by checking the duty point, media behaviour, temperature, cleaning method, connections and any series-specific operating limits. Verified AxFlow source data states nine MDL models with capacities up to 124 m3/h and differential pressure up to 10 bar. AxFlow can help compare the verified data with the required installation conditions.
Tri-lobe rotary design -> Supports smooth, gentle transfer of shear-sensitive products supports process-specific selection and operation. 316L stainless steel rotors -> Provides a verified hygienic material basis for product contact supports process-specific selection and operation. The final configuration should still be checked against the real process conditions.
For Waukesha MDL Sanitary Pump Series, integration should be checked against the existing piping or equipment layout, connections, process conditions and cleaning or control requirements. The verified medium-duty sanitary rotary lobe pump series operating envelope should be compared with the actual duty before replacement or upgrade. AxFlow can support the practical review of configuration and installation requirements.
Yes, AxFlow can support identification of the correct Waukesha MDL Sanitary Pump Series configuration and discuss service or spare-parts requirements. Maintenance planning should reflect the process criticality, wear parts, seals or service items relevant to this series. Contact AxFlow for availability, product selection and a quote.
