Metering Pump -The Effect of Suction Height on Pumped Volume-

November 08, 2021

Changing the suction height affects pumped volume. The higher the suction height is, the smaller the pumped volume becomes. The lower the suction height is, the larger the pumped volume becomes.

The table below shows an example of measured changes in pumped volume resulting from changes in suction height.


Model number used: NRP-500P

Measurement conditions: The pumped volume is set at 500 mm3 when the suction height is 500 mm.


Other than the conditions specified, the measurements follow the standard test conditions.

Note: Details such as specifications, etc., may be changed without notice.
