Pump series NMS

The Packo multistage pumps from the NMS series are equipped with open investment cast impellers and pump casings. They are the right match for operations at moderate flows and high pressures.


  1. Large seal cavity to guarantee liquid circulation around the seal
  2. Solid design thanks to investment cast pump casings and impellers
  3. Open impellers: no axial forces on motor bearings
  4. Monobloc execution with std. IEC motors

Application areas

For use in food, brew, beverage, pharmaceutical and chemical industries, as transfer and mixing pump for liquid food products, drinks, medicines, lotions, etc.

Typical applications: process pump for plate heat exchangers, pasteurizer systems, filters, filling machines, mixers, deaerators, carbonators and high pressure cleaning systems.



Your benefits

  • Ideal for operation at moderate flow rate and high pressures
  • High pump efficiency resulting in lower energy consumption
  • Low NPSH values: less risk on cavitation
  • Electropolished: higher resistance against corrosion
  • Easy & robust construction and easy maintenance: less downtime
  • Standard components
  • Easy to install
  • Open impellers: longer bearing life
