Laboratory Vacuum Pump

Laboratory Vacuum Pump LVP


A number of PVT laboratory operations require the use of vacuum pumps. Leutert diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The two-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum.

All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE-sandwich diaphragms increase reliability and extend operating life. The pump is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensible vapors. It features slim design for space-saving installation and good vacuum performance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory.

Examples of operation

  • outstanding chemical resistance and superior vapor tolerance
  • convenient, quick and simple to use due to the top mounted power switch
  • optimized vacuum even with gas ballast for continuous purge
  • whisper quiet and very low vibration
  • maintenance-free drive system and proven long diaphragm life
