Corrosion-resistant construction resists chemical attack. Operate at rotational speeds of less than 580rpm and feature a large oil reservoir to maintain pumping efficiency—even in dirty applications.

  • Rugged, low-maintenance pump for tough applications
  • Ultimate vacuum, 13.3MPa (1 × 10-4 torr)
  • Low temperatures, degassing and large reservoir extend oil lifetime
  • Gas bubbler allows uniform injection of dry nitrogen into the oil reservoir, degassing the pump fluid and lowering the operating temperature of the oil
  • Pump and motor are mounted on steel base

Use only DirecTorr™ Gold Synthetic Pump Oil in Chemstar Vacuum Pumps
