L-BL2
Volume flow: 27 - 1200 m³/h
Vacuum: 50 mbar (abs.)
The L-BL2 range comprises compact plug-and-play systems for easy on-site installation. The pumps are air-cooled, 100 % oil-free and do not require additional water during operation. In addition, the vacuum pumps provide a much higher resistance to water and steam than alternative systems. Thanks to contact-free compression, they are virtually wear-free in operation and need no periodic maintenance. The patented discharge-air cooling system ensures that the pumps will not heat up by more than 15 K above room temperature. The pumps work reliably in continuous operation and are steam resistant and insensitive to condensation of the pumped air.
Typical applications:
Woodworking, Environmental, Packaging

L-BV54
Intake volume flow: 90 – 340 m3/h
Intake pressure (min.): 100 mbar (abs.)
The Elmo Rietschle pumps primarily prove themselves in applications with damp process gases. They are characterized by an extremely high volume flow (up to 340 m³/h) and achieve intake pressures of 100 mbar (abs.).
The effort required for pre-separation of liquids is reduced or preseparation can be completely eliminated. The use of an additional water pump is no longer required in most cases.
Optimizations of the flow geometry in the block pumps have led to very low power requirements and extremely low noise levels. The single-stage, compact, rugged design minimizes the space needed and ensures virtually maintenance-free
operation.
The benefits are obvious. Liquid ring vacuum pumps L-BV54 will considerably reduce your costs for installation, operation and service.
Advantages:
• High water carryover of up to 6 m3/h
• No need for pre-separation
• Very high volume flow
• Worldwide use thanks to voltage range motors
• Low power requirement
• Extremely low noise level
• Enormous reduction in costs for installation, operation and service
Typical Applications:
EPS foaming (molded parts of Styrofoam, Calibration tables (manufacturing of plastic profiles and plastic pipes)

SK series water ring vacuum pump and compressor are used to suck in or compress air and other air that have no corrosives, undissolvable, and without solid particles, in order to form the vacuum and pressure in the airtight container, gas mixed with a small amount of liquid is allowed. SK series water ring type vacuum pump and compressor are widely used in machinery, petrochemical industry, pharmacy, food, sugar industry and electronic field. Because in the course of job, the compressed gas is constant temperature, it is impossible to cause danger while compressing the explosive gas, thus its application is more extensive.
- Compact structure

LR Single and Two Stage Liquid Ring Pumps
The Edwards single and two stage liquid ring vacuum pumps provide the optimum solution for many rough vacuum applications in the chemical and allied process industries. Single stage liquid ring pumps are suitable for continuous operation on pressure from atmosphere down to 100 mbar, while the two stage configuration offers greater efficiency at low pressures. Both configurations can handle wet corrosive process streams and are tolerant of particulates while offering minimal maintenance requirements, vibration and noise.
LR1A Liquid Ring Pumps :
The LR1A Series of Liquid Ring Vacuum Pumps provide a single-stage design and curved blade impellor with reinforcing rings for improved ruggedness, reducing noise and vibration. Capable of handling wet or dry gases with a high tolerance to liquid carry over, the LR1A Series has an enhanced bearing design enabling reduced internal clearances for improved efficiency.
Pumps are available in cast iron and 316 stainless steel construction as standard with other materials and corrosion-resistant coatings available. All are tested to DIN 28431:1987and are available as part of ATEX Category 1 and 2 T4 systems.
The LR1A pumps are bare-shaft machines and can be supplied as part of a standard package, incorporating electric motor, base-plate and seal liquid recovery system, suitable for once through, partial or total recirculation. Custom-engineered packages are also available.
