Alfa Laval SRU rotary lobe pump

The Alfa Laval SRU rotary lobe pump is a positive displacement pump for gentle

handling of sensitive process fluids in demanding hygienic applications.

High-precision rotors and low-shear, low-pulsation pumping action ensure reliable,

continuous performance and superior energy efficiency. Its contamination-proof

design ensures compliance with the most stringent hygienic design standards

and the requirements for Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP)

validation.

High pump efficiency and gentle product treatment optimize

contamination-free transfer of viscous products

• Maximize uptime through consistent performance

• Raise product quality due to gentle, low-shear product handling

• Increase product safety and quality due to hygienic design and validated

cleaning processes

• Add more process flexibility with versatile handling and efficient pumping of

various products, including viscous media

• Low-maintenance design – a robust gearbox construction with heavy-duty shafts,

torque locking assemblies and taper roller bearings minimizes service

The Alfa Laval SRU rotary lobe pump provides high-efficiency fluid transfer, maximizing

uptime while minimizing contamination risks and maintenance costs.

Its low-pulsation, low-shear pumping action transfers media of varying viscosities with

ease. Modular design provides great flexibility to tailor a pump to meet specific process

requirements.

Available with 12 different pump head displacements, the SRU rotary lobe pump handles

flow rates up to 106 m3/h, differential pressures up to 20 bar and temperatures up to

200°C.

How does the SRU rotary lobe pump work?

Consistent performance

The reliable SRU rotary lobe pd pump features a front cover seal with defined

compression, rotor nut retention design, drainable pump head and ultra-clean surface

finishes to maximize uptime and minimize contamination risks.

Greater flexibility

Modular design and a broad range of models, capacities and options provide versatility

to meet specific application and process requirements.

Low maintenance

A robust gearbox construction with heavy-duty shafts, torque locking assemblies and

tapered roller bearings minimizes maintenance requirements.

Certification, specifications, and standards

SRU rotary lobe pumps meet the requirements of global hygienic standards, including

3-A Sanitary Standards and FDA standards. The pumps can also meet ATEX requirements

for use in explosive environments.
