High-Vacuum Pumping Station with Pfeiffer Turbo and Rotary Vane Backing Pump - EQ-PV-HVS2-LD

Product Options

This Turbo-molecular Pumping Station consists of World-famous Pfeiffer's Turbomolecular Pump and High Speed (156L/min) Rotary Vane Backing Pump. Such a combination provides faster evacuation speed and enables efficient pumping of larger tube chambers up to 100 liters. The backing pump and turbo-molecular pump are installed inside the mobile cart, including vacuum gauge, KF40 SS vacuum bellows, and front LCD digital display. 600 x 600mm mobile table can load any furnace up to 600 Lbs. It is an ideal tool for most of MTI's tube furnaces to achieve high vacuum >10^-4 Torr.

Mobile Cart Structure
  • Mobile cart size: 600 (L) x 600 (W) x 700(H), mm
  • Max. Loading: 600 Lbs. on top
  • Molecular pump control Panel: LCD digital
  • Inside: Pfeiffer vacuum pump made in Germany
Control panel
  • One button operation - the mechanical pump and the turbo molecular pump will start after pressing "start" button
  • System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber.
  • Self-protection - the system will protect the pump from damage by overheating and overcurrent if the leaking rate of the reaction chamber is too high to achieve the high vacuum. 
  • LCD screen - double lines parameters checking interface make the working easier to be handled. 

Turbo Pump and Accessories

  • One 600mm length SS vacuum bellows is built-in from the station.
  • One 1000 mm length SS vacuum bellows with KF25 port is included in the standard package for extended connection distance to other equipment.
  • One KF-25 Vacuum Right-Angle Valve and three KF25 quick clamps are included in the standard package.
