Liquid Ring Vacuum Pumps
EVP liquid ring vacuum pumps are positive displacement machines used in various industries. They provide essential process vacuum by utilizing a liquid, often water, as a sealant. With a straightforward and safe design involving no contact between parts, these pumps efficiently handle contaminated gases.
These machines are found in single- or dual-stage setups and can be adapted as compressors for added versatility. Their applications range from power and coal industries to paper and petrochemical sectors, proving their reliability in numerous processes.
Rotary Vane Vacuum Pumps
A rotary vane vacuum pump creates suction by compressing air within its chamber, effectively extracting air molecules from a designated area or vessel. This pump operates through positive-displacement principles, making it reliable for a wide range of industrial and scientific processes.
When selecting a vacuum pump, the desired vacuum level and quality play a pivotal role. Vacuum types include rough, high, and ultrahigh vacuums, distinguished by pressure and molecule count per cm³, determining their effectiveness.
Roots Vacuum Pumps
A roots vacuum pump is a rotary positive-displacement pump featuring two closely spaced, symmetrically-shaped impellers that rotate inside a casing. These components are found inside a figure-8 cross-section and are synchronized through toothed gears, maintaining minimal clearance to prevent wear.
Unlike other models, roots pumps operate without oil, allowing high speeds. However, this design limits compression ratios. Gas compression also relies on alternating surface allocation, while optimal performance occurs around one mbar.
