R-Series – Rotary Lobe Blowers

These compact rotary lobe blowers belong to the group of dry running positive displacement pumps. This means that there is no need for oil or grease in the compression chamber. Only gear box and bearings, which are separated from the pumping chamber, are oil lubricated. Two non contacting triple lobed rotary lobe rotors rotate against each other in the compression room.

The triple lobed rotors avoid pulsation problems. The blowers are customized to cater for the varying demands of our customers‘ applications.

Advantages at a glance

  • The monoblock construction of the L-BV7/L-BV2 far surpasses conventional modular pumps and is particularly suited for use in the plastics and medical industries.
  • more
  • The robustness and reliability is unparalleled in operation. The machines are available in various combinations of materials such as stainless steel, bronze, ceramic and cast iron with ceramic coating. This enables them to be tailored to the respective operating requirements and thus provides long-term resistance to erosion and corrosion. The entire L-BV range shines with quality: reinforced stainless steel shafts in the pump section and roller bearings with additional lubricant reservoir provide safe and maintenance-free operation even under heavy loads.
