A smart rotary vane vacuum pump

Varian Inc. has introduced a range of high-speed, dual-stage rotary vane vacuum pumps with truly “smart” capabilities. They are medium-sized primary pumps capable of addressing all the requirements of analytical instrument manufacturers. The new pumps perform independently from the main voltage and frequency, allowing them to be used with the full range of voltages. The HS452 and the HS652 include new features such as: auto diagnosis of the electronics and mechanics of the pump, remote control of the pumps and an automatic lubricant level and working temperature sensor. With an 80% reduction in the installation power requirement, the new rotary vane pumps are able to handle the high-capacity flow requirements of LC-MS instruments systems with the electrical power requirements typically associated with GC-MS.
