The following links give instructions on installing and using the pumps:

The set pumped volume may change, or repeatability may decrease depending on usage conditions. Following are the examples of factors that affect the pumped volume and the repeatability of the metering pumps. Please note the following factors before using the metering pumps.


Factors that affect pumped volume and repeatability:

 

Usage Precautions

When a pre-set pumped volume is small, it may take a long time to completely displace the air inside the metering pump/piping with liquid. At the initial discharging of the metering pump, the displacement of the air can be done much faster if the pumped volume setting is set to around the maximum value.

The displacement efficiency of gas varies according to the installation position of the metering pump. It is recommended to install in the recommended place since the position influences the displacement of gas bubbles formed in the fluid.

The pumped volume value set may alter if the volume adjustment screw is loose. Please tighten the locknut firmly to prevent such a problem.

When you decrease the pumped volume by turning the volume adjustment screw clockwise, please do not turn the volume adjustment screw with excessive torque while exceeding the adjustable range. It may cause pump failure.

When you increase the pumped volume by turning the volume adjustment screw anticlockwise, please do not turn the screw too much. If the volume adjustment screw is turned more than the maximum pumped volume, the volume adjustment screw may become detached from the metering pump, and there is a risk to the internal parts of the metering pump.
