Type11: It is a piston - type hydraulic pump, belonging to the K5V series of Kawasaki. It adopts an axial - piston structure, which has the advantages of high efficiency and reliability.
Displacement: The displacement is 140
cm
3
/rev, which means that the pump displaces 140 cubic centimeters of oil per revolution.
Pressure
Rated Pressure: It is 34.3 MPa. This is the pressure at which the pump can continuously operate stably under normal working conditions.
Peak Pressure: It can reach 39.2 MPa. This is the maximum pressure that the pump can withstand for a short time under special circumstances.
Speed
Max Speed for Self - priming: It is 2160 rpm. This is the maximum rotational speed for the pump to self - prime.
Max Speed: The maximum rotational speed is 2500 rpm, which can meet the requirements of the hydraulic system of Kobelco SK330 - 8 and SK350 - 8 excavators.
Torque
Max Input Torque of Tandem Pump: The maximum input torque of the tandem pump is 843 N·m, which reflects the driving ability of the pump.
Weight: The mass of a single pump is 68 kg, and the mass of a tandem pump is 125 kg. The weight of the pump has a certain influence on the overall weight and balance of the excavator.
Control Mode14: The K5V series pumps have various control modes and can respond to mechanical, hydraulic, or electrical inputs, providing flexible control methods for the hydraulic system of the excavator.
Material1: The pump body is usually made of alloy steel, which has high strength and good wear - resistance to ensure the durability of the pump under high - pressure and high - speed working conditions.
