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 deform the bellows.

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 0-40C.
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. With the FW-20H, for example, a cylinder surface temperature rises up to 75ºC when
liquid temperature is 180ºC and ambient temperature is 17ºC.

Noise from pump
Exhaust noise accompanies pump operation. Provide noise insulation as necessary. With the FW-20H, for
example, a noise level rises up to 70.7dB (A) at 120spm and 0.5MPa (supply air pressure).

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 FDC-1
controller is needed. Always install QEVs (quick exhaust valves) to secure system
safety. Purchase separately.

Discharge line

The pipe resistance increases as a discharge line becomes longer or the number of bends increases. In
order to decrease pipe resistance, install a dampener and minimizes pulsation.

Select a valve with an orifice equal to or larger than pipe I.D. A valve with a small orifice may increase the pipe
resistance or easily be clogged with crystals. Always open valves during operation. Do not close the valve until
the discharge pressure reaches "0" after the pump is stopped.

Degassing
Gas bubbles are generated when a strong acid is fed into the reaction tank or liquid is transferred through a
narrow tube. If such bubbles enter the bellows, the pump runs dry, increasing stroke rate or disturbing liquid
transfer. Take a proper step for degassing.
