The GLD series of direct drive rotary vane pumps is ULVAC's reliable high performance pump available in a wide range of pumping speeds from 48 up to 336 L/min. Featuring low vibration and low noise the GLD is ideal for a wide range of sensitive applications and is the choice pump for many OEMs.
Features
- The two-stage exhaust system has lower pressure (good vacuum) than the one-stage exhaust system.
- Low noise and low vibration.
- The backflow prevention mechanism prevents oil from flowing back to the vacuum chamber when it is stopped due to a power failure.
- The exhaust speed is stable due to the installation of the forced oil supply mechanism.
- Operation from atmospheric pressure is possible.
- Easy connection by internal components knock pins and maintenance by flange motor
Applications
- Chemical, science experiment, Analyzer and Laser system.
- Backing pumps for the electronic microscope.
- Semiconductor equipments, sputtering equipments, vacuum evaporation equipments.
- Vacuum dryer, freeze dryer.
