Overview
Introduction
Pump characteristics, features and part names are described in this sec-
tion.
Introduction
Pump structure & Operating principle
The FLP-75W is a pneumatic drive pump with a pair of bellows and is controlled with the LPC-1 controller. The
special design of this pump alone reduces discharge pulsation without the assistance of a dampener, as low as
the combination of existing models and a dampener can achieve.
Principle of operation
The LPC-1 controller determines and keeps the optimal movement of the bellows with the right-and-left dis-
placement sensors and timely supply-air switching. This mechanism ensures the minimum discharge pulsation
at any operating conditions as long as specifications are met.
Supply-air switching
The LPC-1 controller determines an ON/OFF time of the solenoid valves by the input from displacement sen-
sors (ON time) and proximity switches (OFF time).

Overview
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 ow pulsations one after the other without the support of a dampener.
● No need for a pressure and a ow sensor
Displacement sensors and proximity switches alone monitor bellows movement. Need for a pressure and a
ow sensor is eliminated.
● Capable of high-temperature liquid (up to 180ºC)
● 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 ow under pressure uctuation.
*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.

Overview
Operating conditions
Operating conditions
Pump stroke
Operation over the maximum stroke rate can take in a large amount of air during operation. Set the maximum
allowable speed at each supply air pressure range as a fast alarm speed into the LPC-1 controller.
Stroke rate at each supply air pressure
Items Spec
Supply air pressure 0.41-0.5MPa 0.31-0.4MPa 0.21-0.3MPa 0.11-0.2MPa 0.10MPa
Max stroke rate 90spm 105spm 150spm 125spm 65spm
Supply air pressure range
Observe the allowable supply air pressure range at each liquid temperature below.
Liquid temperature Supply air pressure
5-100ºC 0.1-0.5MPa
101-150ºC 0.1-0.4MPa
151-180ºC 0.1-0.3MPa
* Try to use the lowest possible supply air pressure to protect the lter and bellows and reduce the risk of solution spray.
* A ow rate changes with supply air pressure. Use a regulator to keep the pressure constant.
*The minimum supply air pressure should satisfy the minimum operating pressure of the solenoid valve.
Liquid temperature range
Observe the allowable liquid temperature range of 5-180ºC. Note sharp temperature uctuation (heat shock)
may reduce the life of the pump. Contact us for detail.
Liquid characteristics
■ Do not run the pump with the following liquid:
• Liquid that easily crystallizes
• Slurry
• Low conductivity hydrocarbon liquid
*Crystallization or the delivery of slurry remarkably shorten the lives of valves and bellows.
*Delivery of low conductivity hydrocarbon liquid can cause electrostatic discharge (ESD) damage.
■ Use care handling the following liquid:
• Stripper
• Solvent
• Hydrazine
• Fuming sulfuric acid
*Some strippers cause cracks on the PFA bellows and piping, and therefore a warranty period is shortened. Contact us for
detail.

18 Operating conditions
Operation and Stoppage
■ During operation
Make sure a suction and a discharge line are fully opened.
■ When stopping the pump
•Before stopping the pump, make sure the discharge line is open to the atmosphere. Otherwise, the bellows
may deform.
•Do not close a discharge valve as stopping the pump, or an impact pressure may damage the bellows or
check valves.
■ During stoppage
• Always check the specication of the double solenoid valve before installation. Some types (pressure centre
types) are designed to pressurize both the right and left air chambers at the same time.
• Do not leave the pump with any chemical in the bellows for a long period. Some chemical gas can penetrate
the bellows and corrode metal parts.
Air exhaust port
Do not narrow an air exhaust line (for example by reducing the tube I.D.). Or the residual pressure in the pump
may damage the bellows.
*Always observe the minimum composite effective cross-sectional area. Do not extend the air exhaust port too far away
from the solenoid valve (SV) or the quick exhaust valve (QEV). Otherwise, increased pipe resistance may break the limit.
Leak sensors
The sensors occasionally fails to detect leakage depending on operating conditions. Contact us for detail.
Ambient temperature
Observe the allowable operating ambient temperature range of 0-60ºC.
Pump surface temperature
Risk of burning. The surface temperature of the pump or pipe rises high along with liquid temperature in or
right after operation. e.g. cylinder surface temperature rises up to 73ºC when liquid temperature is 180ºC and
ambient temperature is 60ºC.
Noise from pump
Exhaust noise accompanies pump operation. Provide noise insulation as necessary. e.g. a noise level rises up
to 79.4dB (A) at 150spm and 0.3MPa (supply air pressure).

*
Suction lift
This section describes the installation of the pump, piping and wiring. Read through
this section before work. To operate this pump, a 5-port solenoid valve and LPC-1
controller is needed.
Points to be observed
Observe the following points when installing the pump.
• Be sure to turn off power to stop the pump and related devices before service is per-
formed.
• Be careful for the power not to be turned on during work.
• If you notice any abnormal or dangerous conditions, suspend operation immediately and
inspect/solve problems.
• Do not install the pump in a ammable atmosphere.
• Do not lift the pump by gripping the right-and-left cylinder head covers or the top-and-
bottom covers. The pump can drop unintentionally as one of those parts breaks. Hold
the pump by the handgrips to lift it up.
Pump mounting
Mount the pump in ooded suction or suction lift application.
In flooded suction application:
Place the pump as close to the supply tank as possible.
*Flooded suction is recommended for hot liquid transfer or for
looped system.
In suction lift application:
Observe the maximum suction lift* (1m). Place the pump
as close to the supply tank as possible.
*The maximum allowable suction lift shown above is based
