CAUTION
●If the pipe connected to the outlet had a small diameter or attached
foreign substance inside, it might raise the pressure inside the pipe
and impair the pump operation. A caution shall be required.
CAUTION
●Take a countermeasure to avoid any direct load to the Pump flange
such like to choose the pipe with bellows to connect with the inlet
and outlet.
CAUTION
●Should the Pump sucked the water or substance such as dust,
powder and so on, it would impair the ultimate pressure and further
cause a trouble.
The pump has a really slight clearance to keep rotation and easily
gets impossible to rotate by any foreign substance entered inside.
●Pay a full attention to completely clear the welding scale and/or rust
inside the pipe. If obliged to conduct a welding work close to or on
the inlet, take a measure such as to remove the pump unit or put a
cover sheet on the inlet in order not to allow any foreign substance
enter inside.
●Clear the sand completely after having sand blasted the vacuum
container.
●Be sure to mount the leak valve above the mechanical booster pump.
●Check inside the casing before mounting the Pump unit to ensure no
dust is attached to the rotor, casing or elsewhere.
●Metal mesh on the suction inlet is put to keep foreign substances
away from the Pump unit. Be sure not to take it off unless
necessitated so to check it.
CAUTION
●The exhaust ports are provided in two places: the bottom and side
parts. Before use, connect either one to the backing pump. Be sure to
close the other. A flange and an O-ring to close it are provided at the
exhaust port (bottom).
●The flange and the rubber plate provided at the exhaust port (side)
are intended for storage and transportation.
