All pumps are designed with an optimum for robust construction with differential pressures up to 16 bar. 

Special unique designed rotor mounting arrangement making the connection between rotor and shaft very accurate. 

The NOVAlobe rotary lobe pump is designed to minimise downtime for easy maintenance. The seal is front loaded and mounted on a replaceable shaft sleeve in a cartridge arrangement. 

The flexibility of the NOVAlobe remains unmatched. You can combine the standard component to customise the pump to meet every requirement. 

Rotary lobe pumps

From Alfa Laval are able to handle low, medium and high viscosity media. These pumps can be found in virtually every industry where gentle, sanitary processing of viscous product is required.


SRU Rotary lobe pump

Is the workhorse of the rotary lobe pumps range, designed to meet today’s high standards required by the diversity of processing industries. The innovative design combined with the added benefit of optimum spare parts and inventory management gives you total flexibility. The SRU line offers a choice of two high-quality sanitary seals, and there is also a range of stainless steel rotor options.


SX Rotary lobe pump

For when absolutely sterile process equipment is required

SX Rotary lobe pump line

 Is the ultimate solution for ultra-clean processes where product integrity and the cost of the finished product is overriding in the equipment solution decisions. Having genuine front loading options and unique self-cleaning rotor retention device, these pumps offer maximum hygiene integrity.


Positive-displacement pumps

Positive-displacement pumps used in process plants on a variety of process applications. They will handle high viscosity, hot or abrasive fluids, or a combination of all these. These products are manufactured in iron, carbon steel and stainless steel. Available with packing, mechanical seals or magnetically-coupled.
