The Packo twin screw pump ZS series is a versatile positive displacement screw pump that combines the benefits of rotary lobe and centrifugal pumps in one hygienic, efficient design. Engineered for applications requiring the transfer of both high-viscosity liquids and thin cleaning fluids, this two-in-one pump offers pulsation-free operation—ensuring gentle, consistent product handling.
Whether you’re processing delicate foods, pharmaceuticals, or cosmetics, the Packo ZS twin screw pump helps you achieve maximum efficiency, hygiene, and flexibility in your production line.
The ZS twin screw pump operates using two intermeshing screws that rotate synchronously without contact. As the screws turn, they create sealed cavities that move the product smoothly from suction to discharge.
This design ensures:
The identical geometry of the pumping chamber prevents product squeezing, maintaining integrity even for liquids containing solids.
Packo ZS twin screw pumps are ideal for hygienic and gentle transfer of liquids in industries such as:
Thanks to its wide speed range, the ZS pump can serve as both a process pump and a CIP pump, eliminating the need for an additional centrifugal unit.
Yes, the Packo ZS Twin Screw Pump can handle both, eliminating the need for a separate CIP pump.
It features stainless steel 316L construction, smooth surfaces (Ra < 0.8 μm), and is certified to 3A and EC1935/2004 standards.
