Alfa Laval Optilobe rotary lobe pumps

Alfa Laval OptiLobe rotary lobe pumps are versatile alternatives for general applications requiring gentle product treatment and easy serviceability, with high-precision rotors and low-shear operation that ensures gentle handling of delicate products. With full cleanability, the pumps are designed to comply with leading hygienic standards.

The pumps are engineered with a wide performance envelope, due to an advanced rotor shape design and a rotor case that incorporates cusps. In addition to maximising pump efficiency, these designs are said to feature reduced pulsation and noise emissions. The pumps are also designed to reduce the possibility of product damage by internal product recirculation.

Seal faces in the pump have direct contact with high-velocity product media. This is said to ensure a fast and secure cleaning-in-place (CIP) process, reducing both cleaning time and contamination risk. Engineered for use within the food, dairy, beverage and home-personal care industries, the positive displacement pumps conform to CE directives and EHEDG, 3-A and FDA hygienic standards.

Factory-set shimming is said to simplify maintenance by making the process of changing the rotor quick and smooth, with no further adjustment or retrimming needed. The company’s high-precision components also allow for full interchangeability of spare parts.

To meet the requirements of low flow rates and high production capacities, the addition of the Alfa Laval OptiLobe 10 and OptiLobe 50 adds four more pump sizes to the product range. The latest pumps will also provide the possibility of having heating/cooling front covers for processes, where products tend to harden at low temperatures.
