10. For using VFZ501 or VFZ601 in fully closed suction
operation, dismount the emblem at the top of middle
bracket before installation. Dismount the emblem on
the middle bracket surely before installation of the
body.
11. The tone quality of blower noise in this product
changes depending on the Air flow rate, pressure and
fully closed suction operation.
12. Use such pipes as PVC-pipes, gas pipes, flexible hoses etc., which can hold the Vacuum Pump
pressure and hoses other then metallic one for discharge side, use those once, which have a
sufficient high-temperature resistance.
Lay piping so surely as to have no leakage (Figure 3).
Kind of piping for suction port and delivery port.

Ideally, use pipes having the same
diameter as standard pipes.
Caution
䋺
Arrange pipe-supports properly, so that no self
weight and external load concentrate on pipe
connections.
Economical for high pressure
and small Air flow, as small
pipes may be used.
Use large diameter pipes for long
piping having many bends
Pipe joint
Pipe support
Construct piping surely with no leakage.
Pressure and Air flow will be reduced by
leakage.

In case of piping to companion flanges,
companion flanges must be remove form the
Vacuum Pump before piping, it should be
assembled after piping. Take care of the
breakage by tighten pipes too much.
