・Alloy steel plunger & cylinder block with nitriding treatment, outstanding wear resistance
Core friction pairs adopt nitriding hardening process, greatly improving surface hardness and anti-abrasion performance. It maintains high volumetric efficiency under long continuous mining operation, reducing internal leakage and extending service life.
・Integrated variable regulator, intelligent power matching and energy saving
Built-in pressure-flow compound regulator automatically adjusts pump displacement according to load demand. It avoids power waste during light-load operation and protects hydraulic system from overload under heavy load, lowering fuel consumption of mining dumper.
・Heavy-duty cast iron housing, strong impact resistance for mining harsh environment
The pump housing adopts high-density cast iron plus stress-relief annealing, resisting frequent vibration and pressure impact in quarry and mine sites. It prevents shell cracking and deformation under long-time heavy transport cycles.
・Premium FKM sealing system, high temperature resistant and anti-oil aging
High quality fluorine rubber seals are adopted for high temperature resistance and anti-aging performance. It effectively stops oil leakage and maintains stable system pressure even under continuous high-load operation.
・Complete factory hydraulic bench inspection, stable performance and low failure rate
Each pump undergoes pressure, flow, variable response and durability testing before delivery. Strict quality control reduces field breakdown risk and cuts down unexpected downtime for mining vehicles.

FAQ 

Q1: What Volvo articulated dump truck models does part 15020177 fit?
A1: It is compatible with Volvo A35E, A35F, A40E, A40F articulated dump trucks. Please confirm OEM part number VOE15020177 before ordering.

Q2: What signs indicate that the 15020177 main plunger pump is wearing out?
A2: Reduced lifting speed, weak steering force, obvious pressure drop when fully loaded, abnormal internal noise and continuous rise of hydraulic oil temperature.

Q3: What will happen if contaminated hydraulic oil is used for this pump?
A3: Impurities will scratch plungers, cylinder block and valve plate rapidly, causing serious internal leakage, pressure loss and early pump failure.

Q4: What maintenance work should be completed before installing the new 15020177 pump?
A4: Replace hydraulic oil and all related hydraulic filters, thoroughly flush the whole hydraulic pipeline, inspect the hydraulic tank for metal debris, and bleed air after installation.
