The screw spindle pump for food and pharmaceuticals processes
EHEDG compliance, high speed ranges, capable of pumping fluids with very low and very high viscosities and simple fitting and removal - these are the core requirements of the food, drinks and pharmaceuticals industries. The Pomac PDSP double screw spindle pump meets all these and much more: Pomac screw spindle pumps offer high performance, reliability and careful treatment of the fluids being handled. Both simple and complex hygienic processes and applications are their specialty.
You can choose between the PDSP2 and PDSP3 types and various sealing systems and construction materials. Together with our specialists you can configure the perfect solution for your food, pharmaceuticals or personal care application.
Good Reasons for a PDSP Double Screw Spindle Pump
Drawing on the data of your product and your application, our specialists can design an individualized Pomac PDSP double screw spindle pump for you.
Wide speed range for different viscosities
The speed range extends to 3600 rpm. This makes the screw spindle pump suitable for pumping fluids of both very low and very high viscosity. From binding agents, acids and juices to shower gel, adhesives or butter, Pomac pumps are the right solution for both pumping and for sterilizing or cleaning (2-in-1).
High-Precision Screw Spindles
For reliable and efficient operation, these pumps feature two precision-engineered screw spindles that offer optimized play. For each pump size, two different screw types are available that each have a specific thread pitch.
EHEDG Compliance
Pomac PDSP double screw spindle pumps are EHEDG certified. Their construction conforms to the guidelines of the European Hygienic Engineering and Design Group (EHEDG) and is thus optimized for use in hygienic applications. A high level of cleanability is assured.
High suction lift capability
The Pomac PDSP screw spindle pump is self-priming. This means that it can vent the suction line of the pump by itself, without any external aid.
Pumping sensitive media without pulsation
The pump is designed for the transport of sensitive fluids and of liquids containing sensitive solid components. It ensures a flow that is free of pulsation.
Options
Different types of seals available
Single mechanical seal, double mechanical seal or lip seal.
Special materials for shaft sealing
SiC or Tc (wolfram). With Viton® / EPDM / PTFE / Kalrez® o-rings.
Polished surfaces
As a standard feature, all wetted parts are produced with a surface roughness of RA <= 0.8 µm. To comply with food standards, the pump’s surfaces can be polished to a roughness of RA <0.5 µm.
