Figure 3-1 – Vacuum Manifolding with Integral Oil Baffles
As with all rotary mechanical pumps, it is best to
install a flexible member in the suction manifold
of the pump to avoid alignment problems and
to reduce the possibility of transmitting vibration
to and from other components. Self-supporting
bellows-type flexible connectors are recommended
and are available from Tuthill Vacuum & Blower
Systems. Other types of connectors may be too
hard and transmit vibration, or they may be too
soft and may exert considerable force on the pump
and piping when collapsing under atmospheric
pressure. To ensure proper lubrication at initial
start-up, pour a small amount of oil into the pump
suction before connecting the inlet piping.
Make all inlet connections vacuum-tight. Make
sure that the pressure at the end of the connecting
manifold is very close to the pressure obtained with
the pump inlet blanked off. All demountable joints
should be O-ring sealed.
