Product Description

Excavator Hydraulic Pump K5V80DTP-OE25 Hydraulic Piston Pump SY155 Main Pump

Function
This hydraulic main pump is the power core of your excavator. Driven by the engine, it converts mechanical power into powerful high-pressure hydraulic energy and supplies pressurized fluid to boom, stick, bucket, travel and swing motors, supporting all digging and traveling operations.

Type
Our axial variable piston pumps fit most construction excavators perfectly. Medium and large excavator models use integrated dual main pumps together with a rear pilot gear pump.
The dual high-pressure pump features dual independent oil supply design, enabling flexible combined actions via the main control valve, with stable working pressure of 28 to 35MPa.
The rear low-pressure pilot pump runs at 3~4MPa with small flow, delivering reliable control oil for operation levers and valve spools.

Internal Parts
Housing and cylinder block: Built-in pistons rotate with the main shaft to finish oil suction and pressurization continuously.
Adjustable swash plate changes tilt angle to control piston stroke and pump displacement.
The external regulator works with hydraulic signals to adjust the swash plate. Larger angle brings higher flow and faster working speed; smaller angle cuts fuel cost and keeps the engine running steadily without stall.
The valve plate divides oil inlet and high-pressure outlet to ensure smooth fluid distribution.

Three Control Modes
Built-in constant power control lowers displacement under heavy loads to safeguard the engine and make full use of its power.
LS load sensing technology delivers oil flow as required and runs at low displacement when idling to save fuel effectively.
HP pressure cut-off will minimize pump displacement at peak pressure, fully protecting hydraulic tubes and cylinders from cracking.

Common Failures
Worn internal parts or stuck regulator cause internal leakage, making the machine move slowly and lack power.
Regulator fixed at large displacement leads to engine overload, black smoke and stall during heavy-duty work.
Severe internal leakage produces excess heat and makes hydraulic oil overheat. Air intake, low oil level or damaged components will cause unusual noise.

Maintenance
Update hydraulic oil and filters regularly to protect core parts from dirt abrasion. Keep suction pipes sealed to prevent air entry and machine shake. Always maintain correct oil level to extend pump service life.
