Alfa Laval has launched the MaxiLobe and MaxiLobe UltraPure rotary lobe pump series for hygienic and high-purity applications in the dairy, food, beverage, home and personal care and pharmaceutical industries. By delivering the required flow at lower operating speeds, the new positive displacement pumps aim to reduce energy consumption and mechanical stress and, in suitable applications, make it possible to select a smaller pump for the same duty.

Wider operating range, smaller pump

According to the company, MaxiLobe delivers at least 5% higher flow than the equivalent Alfa Laval SRU model under defined operating conditions. Thanks to its wide flow and pressure range, the required duty can be met with a smaller pump in suitable applications; this can lower equipment and installation costs, including the associated electrical equipment, and reduces the need for oversizing.

Because the main connection dimensions are compatible with all Alfa Laval SRU pumps and with most SX and SX UltraPure models, the new pumps can replace older units without modifying existing pipework.

Low-speed operation, energy savings of more than 25%

Alfa Laval states that operating at lower speed can deliver energy savings of more than 25% in many applications. Lower speed also reduces shear on shear-sensitive products. Reduced mechanical stress contributes to longer maintenance intervals and equipment life, while a robust gearbox design aims to reduce the risk of unplanned downtime in demanding conditions.

Russ Kelly, Portfolio Manager Pumps at Alfa Laval, noted that rotary lobe pumps have long been widely used in hygienic and high-purity processes where reliability and predictable performance are vital. He said MaxiLobe builds on this heritage with a hygienic design developed for a wider operating range, enabling smaller pumps to perform the same duty at lower speeds; lower speeds reduce shear, which helps improve operating efficiency and protect shear-sensitive products.

Certifications and traceability

MaxiLobe comes with EHEDG and 3-A certifications and full FDA compliance as standard. MaxiLobe UltraPure, designed for pharmaceutical and biotechnology applications, complies with ASME BPE standards and Good Manufacturing Practice (GMP) guidelines; material options include product-contact materials that meet FDA and USP requirements. Alfa Laval Q-doc documentation provides full traceability and validation support for regulated production environments. Every pump is factory-tested before delivery and shipped with a performance certificate confirming compliance with the specified duty curve.

Maintenance without removing the pump from the line

Front-mounted single seals can be replaced without removing the pump from the process line, which reduces downtime during routine maintenance. Replaceable components and easily accessible shims simplify servicing and help shorten maintenance time.
