With the addition of the models OptiLobe 10 and OptiLobe 50, Alfa Laval extends its range of rotary lobe pumps to provide manufacturers who require hygienic fluid handling solutions with greater process flexibility and enhanced operational reliability at lower flow rates and higher production capacities.

A total of four new pump models in two new frame sizes provides users with both smaller and larger capacities than those previously available. Optional heating/cooling front enable the use of these hygienic pumps in the food, dairy, beverage, and home and personal care industries.

Hygienic Design

Like all pumps in the OptiLobe range, the OptiLobe 10 and OptiLobe 50 pumps comply with international standards, including EHEDG guidelines as well as 3-A and FDA standards. They feature an all stainless-steel exterior, one-piece bearing housing, sturdy gearbox construction with heavy-duty shafts, torque locking assemblies and tapered roller bearings throughout. They are designed for straightforward cleaning-in-place (CIP) and sterilization-in-place (SIP). In addition, the pumps can be completely drained, which eliminates product retention, increases product recovery and reduces the risk of bacterial growth during pump shutdown.

Process Flexibility

OptiLobe offers reliable fluid transfer and gentle product handling in combination with low pulsation, low shear and low noise characteristics. Its inlet and outlet ports in vertical or horizontal position enhance process flexibility and enable universal mounting for complete installation flexibility throughout the plant.

Optional heating/cooling front covers are now available for the entire OptiLobe rotary lobe pump range. The front covers make it possible for users to take advantage of pump quality and cost-effectiveness for processes that require product transfer of low to high product volumes at differential pressures of 8 bar. This is important for processes where products tend to harden at low temperatures, such as sugar solutions, butter and margarines, marmalades, body butters, gels, lotions and other products. Moreover, it is easy to upgrade and retrofit existing pumps with the front covers.

Service and Reliability

The robust gearbox construction enables straightforward and reliable operation. Self-setting, front-loading seals are easy to fit and maintain; there is no need to remove the rotor case for repair or inspection. The high tolerances of all machine components ensure complete component interchangeability without the need for markings or pump retiming. This simplifies maintenance, optimizes spare parts inventory, and significantly reduces overall maintenance costs.
