Series Variable Displacement Piston Pumps
Electro-Hydraulic Proportional Pressure & Flow Control Type
■ Specifications
★1. Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure.
★2. When operating the pump exceeding the rated pressure, operating conditions are restricted.
Refer to page 31 for the details.
★3. Maximum flow differs to shaft speed.
The value listed above indicates shaft speed of 1800 r/min.
For other shaft speed calculate by the ratio of shaft speed.
■ Pipe Flange Kits
Pipe flange kits are available. When ordering, specify the kit number from the table below.
★ 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.

■ Outboard Pumps
A37 to A145 type pumps, except A16/A22/A45, can be
used as double pumps, by connecting an outboard pump on
the cover side. See the table below for details.
● Connectable Outboard Pump
■ Attachment
● Amplifier
● Coupling
Please use assembly part number when ordering coupling
assemblies for shaft connections to outboard pumps.
● Selecting an Outboard Pump Type
The maximum torque of outboard pumps is limited by shaft
and coupling assembly strength. When determining the
outboard pump type, the value of the displacement times
the pressure for a particular pump should not exceed the
value shown in the table below.
★ Connectable pumps shafts are involute-serrated design, not the
standard parallel key slot design. For details, including pump
dimensions and model numbers, consult Yuken.
Note 1. The symbol "★", shown with pump and amplifier model
numbers, is the control pressure at input signal of 5 V.
2. Cable for pump-amplifier connection is not included. See Page
81 for details on ordering cables.

■ Instructions
● Input Signal
The pump is on unload condition when the pump is
operated without input signal voltage.
● Electric Source
Always turn off electric source whenever the connector for
swash plate tilt angle sensor is removed.
●
Compensation of Pump Maximum Regulated Flow at Frequency
If the same maximum flow is required at 50 Hz or 60 Hz,
connect short plug in the amplifier to 60 Hz at the place
where supplied frequency is 60 Hz. At this condition,
maximum flow comes to the same value at 50 Hz.
If short plug is used at 60 Hz without making the change,
maximum flow increased in proportion to frequency.
