SRU Series Pumps

ALFA LAVAL SRU ROTARY LOBE PUMPS

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

Key Features:

Hygienic Design: These contamination-proof pumps meet high standards of hygiene.
Gentle Handling: Furthermore, they provide low-shear and low-pulsation operation suitable for sensitive fluids.
CIP & SIP Compatible: They also handle Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP).
Modular Flexibility: In addition, the modular design allows configuring the pump exactly to meet specific process requirements.

Shaft Seals & Options:

To meet different process needs, the Alfa Laval SRU series positive displacement pump features an R90 external shaft seal, available in various materials and configurations.
Alternatively, the SRU series pumps can be fitted with Hyclean mechanical seals or other seal solutions.
Along with their range of models and capacities in horizontal or vertical porting, the pumps offer additional options, including:
- Standard and custom seals
- Heating/cooling saddles and jackets
- Integrated pressure relief valve
- Rectangular inlet for pumping high viscosity fluids
