AP2D36

Characteristics of the Uchida AP2D36 hydraulic pump

The Uchida AP2D36 hydraulic pump is a high-performance, variable displacement, dual (tandem) axial piston pump that is a key component of the hydraulic systems in mid-range crawler excavators. Its design combines two independent pumps in one robust housing, which allows it to power multiple circuits simultaneously, providing high speed and power for complex operations. With proven reliability and an integrated power control system, the AP2D36 pump ensures efficient use of engine power, stable operation and durability of the entire hydraulic system of the machine.

Technical characteristics of the Uchida AP2D36 hydraulic pump:

• Type: Axial piston pump, double (tandem), with variable displacement
• Design: Swash plate pump. Usually equipped with a third gear pump for the control circuits (pilot line)
• Displacement (piston part): 2 x 36 cm³/rev
• Nominal working pressure: 27.5 - 29.4 MPa (280 - 300 bar)
• Maximum pressure: up to 34.3 MPa (350 bar)
• Maximum rotation speed: ~2000 - 2200 rpm
• Performance (Flow): 2 x ~72-79 l/min
• Direction of rotation: Right (clockwise)
• Weight: Approximately 70 - 80 kg
• Application: Main hydraulic pump for 7-9 ton crawler excavators
