Consistent performance, minimal risk of contamination

SRU rotary lobe pumps are designed with features that maximize performance and minimize the risk of contamination. These include a defined compression front cover sealing, rotor nut retention design, drainable pump head and ultra-clean surface finishes.

 

Safeguarding product quality

Understanding of flow patterns is vital to ensure high efficiency fluid transfer with low pulsation, low shear and low noise characteristics. Alfa Laval employs Computational Fluid Dynamics (CFD) to establish exact geometry for the rotors and rotor case.

 

Greater flexibility and application fit

The modular design of the SRU provides greater flexibility to configure exactly the right solution for specific process requirements.

To meet different process requirements, the SRU features an R90 external shaft seal, which may be specified in various materials and configurations in order to ensure the correct shaft seal for the application. Alternatively the SRU can be fitted with Hyclean mechanical seals as well as other seal solutions.

 

Horizontal or Vertical Porting

SRU pumps are available in both horizontal and vertical port configurations with progressive port sizes and connection options to provide maximum compatibility with existing installations and processes.
