Introduction
Features
● Low discharge pulsation
Displacement sensors and proximity switches monitor bellows movement for the LPC-1 controller to deter-
mine the optimal time to offset flow pulsations one after the other without the support of a dampener.
● No need for a pressure and a flow sensor
Displacement sensors and proximity switches alone monitor bellows movement. Need for a pressure and a
flow sensor is eliminated.
● Capable of high-temperature liquid (up to 180
º
C)
● Capable of high supply air pressure (up to 0.5MPa)
● Safety design
The bellows are welded into the pump head to reduce the possibility of a leak. A leak sensor also installed in
the air chamber to detects an accidental leak by bellows damage.
Operation mode
● MAN mode (Manual operation)
Start/Stop of the pump operation with the LPC-1 controller.
● AUTO mode (Automatic operation)
Start/Stop of the pump operation with the signal input from user's PLC.
● Feedback control
The LPC-1 controller adjusts supply-air pressure to keep a constant flow under pressure fluctuation.
*Use of the CKD EVD3500-010AN-__-3 is required. Purchase separately.
Safety functions
● Leak detection
The LPC-1 controller stops the pump upon detecting a leak from bellows.
● Emergency stop
The pump stops at any time when the START/STOP key is pressed and held (2 sec).
● Interlock
The LPC-1 controller alarms over-seed operation when a pump runs at the fast alarm speed or above. If the
pump speed has reached the interlock speed (fast alarm speed plus 10spm), the LPC-1 controller behaves
to keep it below the interlock speed.
