L-Series – Liquid Ring

L BL2 Pump In Box

L-BL2

To install, simply connect the suction line and motor and fill the water tank—its ready to go!

 


L BV3

L-BV3

Performance strength in the smallest space

The L-BV3 liquid ring vacuum pumps are remarkable—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 6.18 cfm, these little workhorses are particularly quiet and consume very little water. The L-BV3 can handle suction vapors and liquids.

 


L BV2

L-BV7 / L-BV2

Multi-purpose liquid ring pumps

Our L-BV7 and L-BV2 liquid ring pumps are high-efficiency machines which save space and consume up to 50 % less water. These pumps are available in various combinations of materials such as stainless steel, bronze, ceramic and cast iron with a ceramic coating. This enables them to be tailored to the respective operating requirements and thus provides long term resistance to corrosion.

 


L BV5

L-BV5

Monoblock pumps with the highest volume flow

The L-BV5 family is characterized by a very high suction volume

of up to 353 cfm with suction pressures of up to 29 inHg and are primarily used for applications with large quantities of liquids
(2BV54). The L-BV5 also simultaneously works as a condenser while suctioning condensable vapors. This enables the suction volume to be doubled. Reinforced stainless steel shafts, continuously lubricated bearings and a coated pump housing prevent wear and tear caused by solids that are also ingested, and guarantee constant performance, even after many years of use.

R-Series – Rotary Lobe

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.

Standard Systems

liquid ring

LIQUID RING UNITS L-SV

For stable operation, liquid ring pumps must be permanently supplied with liquid, which escapes with the conveyed gas on the discharge side.

That is why we have developed standardized circuit units as system solutions, which feed the operating liquid that escaped on the discharge side completely or partially back into the pump.

Circuit units are available for the full range of Elmo Rietschle liquid ring pumps, with ATEX certification and in stainless steel or cast iron.

Partial circuit

To avoid the heating of operation liquid, only the required part of fresh water is delivered to the pump – against the compression capacity of the pump – that is needed for temperature constancy.

Closed circuit

The liquid circuit is cooled by a heat exchanger. Process gases/vapours stay in the circuit, so contaminated sewage and consumption of fresh water is avoided.

Vacuum Pump Unit X-SC

The vacuum pump units X-SC are a combination of an air-cooled liquid ring circuit unit with patented discharge-air cooling system of the L-Series (L-BL2) and a side channel blower of the G-Series. So the suction capacity in a pressure range of 30 to 120 resp. 200 mbar is multiplied. The aggregates have a robust design, high vapour compatibility as well as an oil-free compression without contact. 

The side channel blower can work at a consistent speed or a frequency converter can be used to enhance the performance of the unit. The operating point can thus be optimized for the application (i.e. pressure constancy control).
