VLM Series Liquid Ring Vacuum Pumps and Compressors
Compared with flat sided liquid ring pumps and compressors, it features high efficiency, energy saving, stability, reliability, and easy maintenance. Capable of simultaneous vacuuming and compression, suitable for negative inlet pressure and positive outlet pressure conditions, with a pressure difference of up to 0.3MPa.
Product Features
Ultimate Vacuum
Vacuum pump ultimate vacuum 5kPa (A)
Maximum Discharge Pressure
Compressor max. discharge pressure 0.2MPa (G), with isothermal compression
Withstand Large Pressure Difference
Capable of simultaneous vacuuming and compression, suitable for negative inlet pressure and positive outlet pressure conditions, with a pressure difference of up to 0.3MPa
Strong Adaptability
Capable of suctioning high-humidity gases (including saturated steam), gases containing solid particles, as well as toxic, corrosive, flammable, explosive, and hazardous gases
Mechanical Seal
Single or double mechanical seal options are available
Rich Material Options
Over 10 material options, including cast iron, stainless steel, or superalloys
Cavitation Prevention
Unique cavitation prevention design
High Efficiency & Energy Saving
Large-diameter radial suction and discharge ports, with the conical portion extending into the impeller chamber, ensure smooth flow with minimal air and water resistance, achieving 10% energy savings
Radial Clearance Insensitive to Operating Temperature Changes
Capable of withstanding unexpected increases in operating temperature
Conical Distributor
Inlet pressure fluctuations have minimal impact on the compressor
Low Radial Force
Low radial forces on shafts and bearings extend service life
Side Discharge Design
Prevents equipment damage from overload during startup
Easy Maintenance
Fewer mechanical parts guarantee easy maintenance
