Pump series ZL

Packo rotary lobe pumps are state of the art. The series can be equipped with a variety of rotors and options to adapt to almost all hygienic pumping applications. This guarantees an optimal and efficient operation of the pumping process.

  1. Available with various rotor geometries (Bi-Wing, Tri-Lobe, Heli-Lobe, Multi-Lobe, Single Wing, Bi-Lobe): the optimal solution is available for every application.
     
  2. Rotors can be changed without timing spindles, or opening the gearbox for adjustments.
     
  3. Available with various sealing arrangements: single, flushed, double, O-ring seal, triple lip seal, etc. which are interchangeable.
     
  4. Wetted seal parts can be replaced without disassembling the rotor case: pump does not need to be mounted out of the installation to change seals.
     
  5. Food grade oil-filled gearbox increases bearing lifetime and requires minimal service effort. Ball bearings generate very low heat, helical and grinded gears guarantee smooth operation.
     
  6. Investment cast stainless steel gearbox available

Application areas

The Packo pumps of the ZL series are designed for a wide range of hygienic applications in dairies, breweries, the pharma and cosmetics industry and bakeries, as well as for pumping liqueurs, detergents, shampoos, gels, etc. They are the ideal solution for gentle pumping of low to high viscous liquids.
