Product Description

SY215-10 SY205C Excavator Hydraulic Pump V90N130VR 211-05220 21105220 Piston Pump for Construction Machinery Parts

Name: SY215-10 SY205C Excavator Hydraulic Pump V90N130VR 211-05220 21105220 Piston Pump for Construction Machinery Parts
Brand: Lanzhou Fudong Guangqi Trading Co., Ltd
SKU: V90N130VR
Availability: InStock

Working Role

Hydraulic main pump is the power origin of excavator hydraulic system, powered by engine to generate high-pressure hydraulic oil for boom, arm, bucket, walking and slewing hydraulic components.

Available Models

Most excavators install axial variable piston pumps; medium and large diggers use one-piece dual main pump with tail pilot gear pump. Main pump pressure 28~35MPa, pilot pump 3~4MPa for joystick and valve spool control.

Internal Parts Intro

Multiple pistons inside cylinder block finish oil suction and compression with shaft rotation. Swash plate angle directly controls pump displacement. Side regulator receives hydraulic signal to swing swash plate for flow adjustment. Valve plate separates low-pressure inlet and high-pressure outlet cavity.

Working Control Logic

Constant power shrinks pump displacement under heavy load to avoid flameout; LS control only supplies needed oil to cut idle fuel waste; pressure cut-off drops displacement to minimum to protect hydraulic accessories.

Repair Common Issues

Worn pistons/valve plate inner leakage or stuck regulator results in slow machine speed; regulator stuck on large displacement causes overload and black smoke; severe leakage makes hydraulic oil overheat; air or insufficient oil leads to abnormal pump noise.

Maintenance Suggestion

Replace hydraulic oil and filters regularly, block air from suction pipeline and maintain normal liquid level to reduce pump failure rate.
