V series Piston Pump
Features
 Low noise
 Low noise operation over the entire pressure range has been realized in each series.
 High efficiency
 Fluid temperature rise can be reduced due to the smaller power loss. This means that the tank can be
designed in a small size.
 High reliability
 High responsivity, high stability, and long life make it possible to increase the reliability of the main machine.

Relationship between the protruding length of the discharge rate adjusting
screw and the discharge rate ( 4 =C)
 Discharge rate adjustment in combination control
The discharge rate for both the low quantity (QL) and high quantity (QH) ranges can be adjusted as follows:
 Turning the adjusting screw clockwise decreases the discharge rate.
 Turning the adjusting screw counterclockwise increases the discharge rate.
The discharge rate adjusting screws are provided with scales on the nameplates as shown below.

Adjust the discharge rate according to the relevant discharge rate adjustment graph by following the procedure below.
(1) For the low quantity range, read the value for the desired discharge rate on the graph and turn the low quantity adjusting
screw to set the scale position to the read value.
(2) For the high quantity range, read the value for the desired discharge rate on the line corresponding to the value for the low
quantity range on the graph and turn the high quantity adjusting screw to set the scale position to the read value.
(3) When adjusting only the high quantity range, loosen the lock nut and adjust as described above.
(4) When adjusting only the low quantity range, loosen the lock nut on the hight quantity adjustment screw and adjust the
setting for the low quantity range as described above while holding the high quantity adjusting screw in place with a hex
key.
Example of adjustment
Example: When adjusting the discharge rate of V15C at 1500 min −1 to 7 L/min for the low quantity range (QL) and 18 L/min
for the high quantity range (QH)
 From the discharge rate adjustment graph for V15C at 1500 min −1, first read the value for QL = 7 L/min, which is 4, and
adjust the low quantity adjusting screw accordingly.
 Then, read the value for QH = 18 L/min on the line for 4 of QL, which is 7, and adjust the high quantity adjusting screw
accordingly.

Factory settings
The discharge rate for the high quantity range is
factory adjusted to the maximum discharge rate and
the discharge rate for the low quantity range is factory
adjusted as follows.
Discharge rate adjustment graph for V15C in combination control
The setting values indicated above may change slightly
depending on the conditions of use (f luid temperature,
hydraulic fluid type, etc.)
For final fine adjustment, repeat the adjustment described
above and achieve the setting appropriate for the actual
application.
