Liquid ring vacuum pump L-BV2 (L_200)

The Elmo Rietschle liquid ring vacuum pump L-BV2 (L_200) monoblock construction far surpasses conventional modular pumps and is particularly suited for use in the plastics and medical industries.

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.

The L-BV3 (L_200)

These liquid ring vacuum pumps are convincing – whether they are used for sterilizers or for medical/laboratory equipment, they excel where extremely small suction capacities are required within a minimum of space.

With a suction volume of up to 11 m³/h, these little workhorses are particularly quiet and consume very little water. It goes without saying, of course, that the L-BV3 can also convey suction-side steam and liquids.

The Elmo Rietschle L-BV3 features an unusually compact design: constructed in our tried-and-tested modular design, it has extremely space-saving dimensions. And also in respect to quality, the L-BV3 leaves no wishes unfulfilled: corrosion-resistant materials, reinforced bearings and a stainless-steel shaft in the pump section all consistently ensure safe and efficient operation even under high loads.

Liquid ring vacuum pump L-BV5 (L_300)

The block pumps in the L-BV5 family are characterized by a very high suction volume and are primarily used for applications with large quantities of liquids. The L-BV5 also simultaneously works as a condenser while suctioning condensable steam. This enables the suction volume to be doubled. The sound pressure level remains under 73 dB(A) and therefore fulfils even the strictest noise stipulations.

The single-stage compact construction of the Elmo Rietschle L-BV5 reduces the space required for the installation of the pumps to around half that required by conventional modular machines. The pump can be easily installed in extruding machines and chemical systems, even when mounted to the underside of the tables. When developing these liquid ring pumps, Elmo Rietschle placed the focus on robustness and reliability.

The L-BV5 can provide up to 20,000 hours of continuous operation without requiring an interruption for maintenance, even under the harshest conditions. Reinforced stainless steel shafts, continuously lubricated bearings and a coated pump housing prevent wear and tear caused by solids that are also sucked in, and guarantee constant performance, even after many years of use.

Liquid ring vacuum pump L-BV7 (L_200)

Our new L-BV7 liquid ring pumps are high-powered and multitalented machines which save space and up to 50% in operating liquids. They can easily convey eight times the quantity of liquid. The monoblock construction of the L-BV7 far surpasses conventional modular pumps and is particularly suited for use in the plastics and medical industries.

The entire Elmo Rietschle 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.
