Pilot Pressure
Control Type
Pressure
Compensator
The pump is used in combination with the pilot relief
valve or multistage pressure control valve. By
controlling the pilot pressure, the full cut-off pressure
can be remote-controlled according to your
requirements.

Constant
Power
Control Type
•
Pump input power can be controlled in accordance
with the motor output.
•
When the discharge pressure rise, the output flow
decreases corresponding to the preset input power.
•
The pump can act for function of two pumps, low-
pressure large-flow and high-pressure small-flow.
Therefore, the motor capacity can be reduced.

Simple Two-
Pressure
Two-Flow
Control Type
•
This type of control enables one pump to act as two
pumps (low-pressure and large-flow/high-pressure
and small-flow-rate). Therefore, the motor capacity
can be reduced.
•
When the system pressure increases near the preset
“PL” pressure due to the load increase, the pump
flow automatically decreases to “QL.”
•
This type of control is suitable for an application
like the press, where switching from rapid
advance to feed is required just when the press
(pressurizing) starts.
•
The PH pressure can be remote-controlled with a
separately located relief valve. With this type of
control, it is easy to change the applied pressure
setting when materials or shapes of the press are
changed.

★1. Whenever setting pressure, make sure the full cut-off pressure never exceeds
the maximum intermittent pressure.
★2. Care should be taken in cases of used at a higher pressure than the rated
pressure, because operating terms may be restricted. For example, if used as
per maximum illustrated operating conditions, intermittent time at maximum
flow is restricted to under 1/5 of one cycle time and under six seconds
simultaneously. Conditions may vary according to the actual working pressure
and delivery (inclination angle of the swash plate). Consult factory or Yuken
sales representative for further information.
★3. Care should be taken in cases of used at a higher pressure than the rated
pressure, because operating terms may be restricted. For example, if used as
per maximum illustrated operating conditions, intermittent time at maximum
flow is restricted to under 1/5 of one cycle time and under six seconds
simultaneously. Conditions may vary according to the actual working pressure
and delivery (inclination angle of the swash plate). Consult factory or Yuken
sales representative for further information.
★1. The figures in brackets are for A22 type.
★2. As the specific gravities of water-glycol fluids and phosphate ester type fluids are higher than one, an overhead reservoir is required when pumps
are operated at 1400 r/min or more.

★ In case of using socket welding flanges, there is a case where the operating pressure should be set lower than the normal because of strength of the
flanges. Therefore, please pay cautious attention to the operating pressure when the socket welding flanges are used.
● Details of the pipe flange kits are shown on page 262.
