Pump controller FDC
As it controls the pump at a fixed level of discharge when it is connected to
a vacuum regulator, stable circulation and filtration continue despite possible
fluctuation of a discharge load due to clogging of the filter or some other reason.
Since the difference between the inside pressure and the outside pressure of the
bellows can be held at a minimum level, an increase in the life of the bellows
is to be expected. Monitoring of the flow rate, the number of strokes and total
count are possible. There are two operation modes; the AUTO mode by external signals
and the MANU mode for manual operation. In addition to the sensor mode for operation
by the proximity switch, the timer mode is provided as standard menu. This
means that if the proximity switch fails, the operation can be continued in the
timer mode. Alarm displays such as leak alarm, pump malfunction alarm are available.

Owing to their function of fixed flow rate control, the discharge of the pump is kept at a fixed level even when the discharge pressure of the pump changes due to filter clogging so as to maintain stable circulation/filtration.
The range of pump pulsation is held always to a minimum level by automatic control of the pressure of the air fed to the dampener. Thus, on-the-spot adjustment of pressure is no longer necessary.
Since the difference in pressures in and out of the bellows is kept to a minimum value despite a change in the pump load on the discharge side, the life of the bellows is extended.

Pump controller AC
This is an inexpensive type controller for the F series pumps.
Upon receiving a signal from the pump's built-in stroke sensor, the controller reliably activates the solenoid.
It functions to output an alarm in case the pump stops or the bellows are damaged.

As its fixed stroke rate control function enables the pump to operate with a fixed number of strokes regardless of a change in the pump load on the discharge side, a stable discharge is maintained. Since it is also possible to keep the differential pressure always at a minimum value, the life of the bellows is extended.
The length of time (reference time) required for one shot of the pump can be set. A time-up alarm is output when the pump operates more quickly than the reference time so as to make one aware of the defective operation of the pump.
In the event damage is caused to the bellows, a leak alarm is output to bring the pump to an emergency stop. |
