YUKEN A3H series hydraulic pumps are high-pressure variable piston pumps developed by YUKEN Company. They have a variety of specifications and models. The following are introduced from four aspects: basic model, suffix combination, complete model example, and control type.：
1. Basic model
The basic models of YUKEN A3H series hydraulic pumps are named according to the displacement size. Common models include：
A3H16, A3H37, A3H56, A3H71, A3H100, A3H145, A3H180
The specifications of YUKEN A37 series high pressure variable piston pump are as follows：
Model description
Take the model A37-F-R-01-H-K-32 as an example：
A: A series variable piston pump
37: Displacement (37 mL/r)
F: Installation method (F is flange type, L is foot seat type)
R: Direction of rotation (R is clockwise, L is counterclockwise)
01: Control method (01 is the pressure compensation control type, 04 is the electro-hydraulic proportional load sensitive control type)
H: Pressure level (H is 1.5~21 MPa)
K: Shaft extension form (K is a flat key)
32: Design number (such as 32393, 32366, etc.).
Technical parameters
Displacement range: The A37 series has a displacement of 37 mL/r, which is a medium displacement plunger pump.
Pressure range: The maximum working pressure can reach 21 MPa (H type).
Control method: Support pressure compensation control (type 01) and electro-hydraulic proportional load sensitive control (type 04).
Application scenarios: It is widely used in injection molding machines, die-casting machines, hydraulic presses, machine tools and walking machinery.
Other features
Structural design: The swash plate variable mechanism is adopted to realize stepless adjustment of oil supply.
Efficiency: High volumetric efficiency, significant energy-saving characteristics, suitable for the needs of industrial hydraulic systems.
For detailed parameters of specific models (such as flow rate, speed, etc.), it is recommended to refer to YUKEN’s official technical manual or contact the supplier for a complete data sheet.
