New Varian HS452 HS 452 Smart Power-Saving Rotary Vane Vacuum Pump PN 9499360

Varian’s NEW HS452 Smart Power-Saving vacuum pumps employ an innovative frequency inverter technology that delivers optimal and consistent performance while encompassing the worldwide range of voltage and frequency conditions. Operating with low power requirements, the microprocessor controlled frequency inverter is an efficient driving unit capable of delivering the high starting torque required of a dual-stage oil pump. HS452 technology solves the common problems inherent in traditional single-phase motors. Smart Pumps start with inrush current about 7 times lower than that of equivalent traditional pumps. Inverter technology reduces the power required compared to traditional single phase motors. Circuit-breakers are no longer required, resulting in reduced system costs. Unlike traditional pumps, Smart Pump’s software driven startup procedure recognizes faulty pumps within seconds, and so avoids uncontrolled load conditions. The result is very easy pump integration.

These Varian HS452 Smart Power-Saving vacuum pumps offer truly universal single-phase input voltage and frequency which provides worldwide compatibility and constant performance at different input frequencies (100-120/200-240 V ±10%, 50/60 Hz). The 3-phase inverter output is constant and independent of single-phase input frequencies and voltages. Motor efficiency and power factors remain optimal and as a result motor and pump working temperatures remain low and constant worldwide. Smart Pumps can be remotely driven via discrete I/O or RS232/RS485 interfaces. Varian’s T-plus Navigator Software facilitates communication making it very easy to drive the pump. Pump performance can be tailored by setting the rotational speed for specific applications. The software monitors and logs pump parameters making it possible to perform pump and system diagnostics.

Steady state high gas load applications exploit the major benefits of the smart technologies. When operated at pressures lower than the auto-tuning pressure, the Varian HS452 outperforms the equivalent traditional DS402 and DS602 pumps by 10% at 60 Hz and by 30% at 50 Hz. The Smart Pumps can run below auto-tuning pressure at their full speed of 2000 rpm. Despite the lower power requirements of 780 W max, the Smart Pumps deliver good performance in the roughing phase. This Pump has a Pumping Speed of 15.4 CFM. The complete specifications and instructions user's manual in PDF format can be downloaded below.
