Alfa Laval extends its hygienic rotary lobe pump range for lower and higher capacities



Alfa Laval announces the addition of two new frame sizes as well as optional heating/cooling front covers to its broad range of Alfa Laval OptiLobe rotary lobe pumps. To meet the demand for smaller and larger hygienic pumps that can handle low flow rates, the new OptiLobe 10 and OptiLobe 50 add four new pump models to the range. Optional heating/cooling front covers make it possible to use this pump in a wider range of general hygienic applications within the food, dairy, beverage, and home and personal care industries.

With the addition of the Alfa Laval OptiLobe 10 and OptiLobe 50, Alfa Laval extends its proven range of OptiLobe 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.

“Market trends indicate a need for cost-effective hygienic rotary lobe pumps that handle both smaller and larger flow rates, yet still comply with the latest quality and hygienic standards,” says Leonardo Morabito, Portfolio & Project Manager Pumps, Hygienic Fluid Handling, Alfa Laval. “The OptiLobe 10 and 50 meet this demand. The new sizes and options promise to be a great asset for any user who relies on hygienic processing.”

The total OptiLobe pumps range comply with international standards, including EHEDG guidelines as well as 3-A and FDA standards. The pumps 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). What’s more, it is easy to completely drain the pump, which eliminates product retention, increases product recovery and reduces the risk of bacterial growth during pump shutdown.

With the addition of these new pumps, the Alfa Laval OptiLobe rotary lobe pump range now offers a total of 10 models and five frame sizes (10, 20, 30, 40 and 50). All 10 pump models are capable of cost-effective operation at differential pressures of 8 bar.

Service and reliability

Self-setting, front-loading seals are easy to fit and easy to 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 reduces maintenance costs and downtime, thereby optimizing production uptime. This simplifies maintenance, optimizes spare parts inventory, and significantly reduces overall maintenance costs.
