■Length of Discharge-side Piping
and Discharge Volume
The graph below shows the relationship between piping
length and discharge volume. Installing a damper
lessens piping resistance and allows the length of the
piping to be extended.

■Discharge Performance of
High-viscosity Liquids
When a fast stroke speed is set for transferring high-
viscosity liquids, piping resistance on the suction side
may cause the amount of sucked in liquid to be
reduced.
