When the pump is operated first time together with the dampener, check the followings.
(1) Check to see if no damage, loosened bolts or leakage are found on dampener (pump).
(2) Air pressure adjustment
This auto-dampener automatically adjusts the air pressure to be sealed depending on handled liquid pressure, which
requires no adjustment on the dampener.
Order
Operation
Check items
1
Start pump.
Confirm if liquid is discharged normally.
3
Refer to Operating Instruction of pump for details of pump operation.
4
If no abnormality is found, start full operation.
2
Adjust pump discharge capacity and pressure.
Confirm by pressure gauge if air pressure does not
exceed specified pump pressure.
1. Preparation for operation
2. Operation
CAUTION
Right after the pump starts, the dampener exhausts air intermittently. This is because
the pressure adjusting valves function until load fluctuation is gone. Note that this is not
abnormal. Installing the muffler into the exhaust port, the exhaust noise can be reduced.
(Fitting bore: RC1/4)
CAUTION
Check that pneumatic pressure is applied to auto-dampener while pump operation. If
pneumatic pressure is not applied, pulsation dampening effect may be reduced or bellows
may be deformed.
In case the bellows of dampener is broken, it may happen the pumped liquid gets into
pneumatic piping. Take suitable protective measure in the system.
CAUTION
When the pump operates at 30 spm or below, the air is exhausted from the dampener in
sync with operation.
