Packo Rotary Lobe Pumps ZW

The ZW series Packo pumps use standard rubber heli-lobe rotors designed to handle liquids with small particles like grape skins, seeds and stems. The soft rubber rotors prevent damage and ensure high efficiency. These pumps are ideal for transferring wine, juice, pomace and similar liquids.

Features of the Global Pumps range of Packo rotary lobe pumps include:

  • certificates: FDA, EX, EAC
  • sealing options: Choose from various sealing arrangements and materials, including single, double, and triple lip seals
  • front loaded single mechanical seals
  • added features: stainless steel trolley and the option for a built-in frequency converter
  • max. flow rate: 50 m3/hr
  • max. viscosity: 1,000,000 cP
  • max. differential pressure: 8 bar
  • max. temperature: 120 ºC


While operating similarly to standard models, this lobe pump sets itself apart with highly polished internals. The polished surfaces not only contribute to efficient operation but also make cleaning easy—a critical factor for preventing bacterial contamination in sensitive applications.

Moreover, lobe pumps excel in handling products gently, making them ideal for shear-sensitive materials. With strong self-priming capabilities ensuring efficient start-up, they are a reliable choice for applications that require precise flow control.

In summary, lobe pumps offer a simple yet effective solution for hygienic and efficient fluid transfer.


The Packo ZW series pumps, featuring standard rubber heli-lobe rotors, are tailored for pumping liquids with small particles like grape skins, seeds, and stems.

Thanks to their soft rubber rotors, there's no risk of rotor damage or galling. Plus, the close clearance between these soft rubber rotors and the rotor case delivers top-notch efficiency and minimises any product handling issues.

For a range of applications, from wine and juice to pomace, Packo rotary lobe ZW pumps are your go-to solution, combining practicality and performance with ease.
