・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: Which Volvo articulated dump truck models does part 15020179 fit?
A1: It is compatible with Volvo A35E, A35F, A40E, A40F and A45G articulated dump trucks. Please confirm OEM part number VOE15020179 before ordering.

Q2: What are the early warning signs of 15020179 pump performance degradation?
A2: Slow hoisting speed under full load, insufficient steering power, pressure drop during climbing, abnormal rattling noise and gradual rise of hydraulic oil temperature.

Q3: What damage will happen if the pump runs continuously with contaminated hydraulic oil?
A3: Hard particles in hydraulic oil will scratch plungers, cylinder block and valve plate, creating serious internal leakage, pressure loss and permanent damage of the hydraulic pump.

Q4: What preparation work needs to be completed before installing this new main pump?
A4: Replace hydraulic oil and all relevant hydraulic filters, flush the entire hydraulic pipeline thoroughly, inspect the oil tank for metal debris, and bleed air from hydraulic circuit after installation.
