Diffstack Pumps are designed and manufactured to suit
the needs of both industrial and laboratory
applications. These Diffstack pumps are offered in sizes
-2.5 inch, 4 inch, 6 inch and 10 inch diameters. The
superior pumping speed of Diffstack Pumps makes them
exclusively suitable for Vacuum Furnaces, Space
Research, vacuum coating of lenses, Thin Film Deposition
and several other industrial applications. These pumps
are capable of achieving vacuum in the range of 10-6 to 10-7 m.bar.
The
main body is fabricated from stainless steel in the
shape of a cylinder and water cooling copper coils are
wrapped around the body.
The
jet assembly consists of metallic nozzles aimed
downwards facing the pump inner body so as to cool the
vapor molecules emerging from these nozzles. The oil
boiler, with external flat type heating coil for burst
free evaporation, is located at the bottom of the pump
and it holds specified quantity of oil for efficient
working of the pump. An ultimate vacuum in the range of
5 x 10-7 m.bar can be achieved by
using Dow Corning 704 Silicon Fluid, as this fluid does
not oxidize by air and is chemical resistance which
eliminates frequent replacements.
These
pumps are built in with water cooled cap over the jet
assembly so as to trap the back streamed oil vapors thus
producing clean and better ultimate vacuum over
conventional Diffusion pump. Other features is, pump is
built in with High vacuum valve such that it can be used
as high vacuum pumping unit with suitable backing pump.
