SRU Series Pumps

ALFA LAVAL SRU ROTARY LOBE PUMPS

Harco offers the Alfa Laval SRU rotary lobe pumps, engineered to provide reliable performance, trouble-free operation, and superior energy efficiency for demanding applications. The SRU series are Alfa Laval’s core rotary lobe pumps for the gentle handling of sensitive process fluids within the dairy, food and beverage, biotechnology and pharmaceutical industries.

These Alfa Laval SRU contamination-proof pumps meet high standards of hygiene, low-shear and low-pulsation operation, and handles both Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP).

Alfa Laval’s SRU’s rotary lobe pumps modular design offers greater flexibility to configure exactly the right solution for specific process requirements.

To meet different process requirements, the Alfa Laval SRU series positive displacement pump 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 series pumps from Alfa Laval can be fitted with Hyclean mechanical seals as well as other seal solutions.

Along with there range of models and capacities available in horizontal or vertical porting, the Alfa Laval SRU series rotary lobe pumps come with other options, including standard and custom seals, heating/cooling saddles and jackets, an integrated pressure relief valve, and a rectangular inlet for pumping high viscosity fluids.
