The Leybold D40B is a Rotary Vane Pump, direct drive,
oil-sealed vacuum pump designed for continuous operation to
760 Torr. They find use in a wide range of medium and medium-high
vacuum applications characterized by the presence of corrosive or oxidizing gases.
and can also be used as backing pumps for Roots pumps, diffusion
pumps, turbo-molecular pumps and cryo-pumps.
Leybold D40B vacuum pumps are rebuilt by Queen City Semiconductors and offered with optional
Variable Frequency Drive (VFD) controlled motors.
The D40B pump will not require service as often with a VFD installed and will
use 60% less power in most cases.
VFD controlled pumps will last much longer on plasma etching systems that
expose the D40B to caustic gases.
These pumps are available with Krytox, Fomblin (PFPE) for corrosive/explosive
gases or Hydrocarbon oil prep for pumping air.
Rebuilt Leybold Rotary Vane Trivac Mechanical Vacuum Pumps
include a 1 year warranty on parts and labor.
The warranty is void when failure is due to oil contamination or misuse.
Queen City Semiconductors offers the CFS filtration, ARS exhaust filtration with paper or stainless steel filters for the D40B.
Queen City Semiconductors rebuilds will rebuild your vacuum pump or take your pump in trade for a pump already rebuilt.
