EC120D EC140D Hydraulic Pump for Volvo Excavator spare parts VOE14717725 K3V63DT‑1ZER‑9N0Y OEM

Product Brief

This OEM‑spec variable axial piston pump VOE14717725, model K3V63DT‑1ZER‑9N0Y, serves as the core hydraulic power source for Volvo EC120D and EC140D medium‑size excavators. It converts engine torque into adjustable high‑pressure hydraulic flow to complete earth digging, material loading, trench excavation and compound swing‑travel actions. Widely deployed in road construction, municipal renovation and quarry working conditions, this replacement pump is heavily sourced by overseas maintenance contractors, rental fleet operators and cross‑border spare‑part wholesalers for direct unit swap and full hydraulic system overhaul of Volvo D‑series fleets.

Under continuous site operating conditions including heavy cyclic load, hydraulic oil impurity contamination and frequent pressure fluctuation, the original pump will gradually generate cylinder block scuffing, piston shoe wear, valve plate erosion and increased internal leakage. Common fault performances contain insufficient digging output, sluggish combined movements, weak traveling power, continuous hydraulic oil overheating, obvious pump vibration and knocking noise under digging load. Once the main pump suffers sudden failure, the whole machine stops operation directly, bringing extra repair expenditure and project schedule delay for equipment owners.

Our OEM replacement pump strictly follows original drawing standards for mounting hole layout, input shaft spline, oil port position and regulator preset pressure parameters. No cutting, drilling or extra adapter modification is needed during field installation, which effectively reduces machine downtime. Compared with high‑priced genuine Volvo pumps with unpredictable lead time, this hydraulic pump maintains reliable site adaptability and meets repeated bulk‑order procurement needs for global dealers focusing on Volvo excavator spare parts.

Product Highlights

1. High‑precision dimensional replication for field fast replacement
All installation dimensions, spline tooth parameters and oil port positions keep consistent with original OEM specs. Service technicians can finish pump replacement work without secondary on‑site machining, lifting repair efficiency for heavy‑duty overhaul and used‑equipment refurbishment projects.

2. Reinforced friction‑pair craftsmanship for complex construction environment
Many low‑cost substitute pumps will experience sharp performance drop when matching aged hydraulic systems carrying tiny impurity particles. Our core internal friction parts adopt optimized heat‑treatment plus multi‑process fine‑lapping technology, delivering outstanding anti‑wear and anti‑pressure‑shock performance. It cuts pump replacement frequency for EC120D / EC140D machines running on municipal jobsites and medium‑intensity earth‑moving locations.

3. Full‑set bench performance verification before goods delivery
Each finished hydraulic pump will go through pressure endurance test, flow calibration and sealing leakage inspection on professional hydraulic test bench before packing. Potential defective products are screened inside factory, lowering re‑work risks for repair teams and avoiding unexpected site shutdown caused by pump breakdown.

4. Cost‑competent OEM alternative for medium‑size excavator fleet maintenance
Genuine OEM hydraulic pumps for Volvo EC D‑series excavators carry high purchasing cost together with unstable stock availability. Our factory‑direct OEM‑replacement pump balances stable running performance and reasonable cost, helping machinery owners and service shops control total overhaul expenditure for Volvo medium excavator fleets.

5. Flexible logistics solutions oriented to bulk‑purchase merchants
In‑stock items support prompt shipment after payment confirmation. Air freight can be arranged for urgent on‑site breakdown repair orders. Sea consolidation and full‑container transport options help global bulk importers decrease overall logistics expenditure.

Factory Production Strength

Our production base specializes in R&D and mass manufacturing of OEM‑replacement hydraulic spare parts for European brand excavators, including main hydraulic pumps, travel gearboxes and swing motors. We possess complete production workflows: alloy‑steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench validation. Simulated heavy‑load cycling tests are implemented to verify component durability matching real‑world municipal construction and road‑building scenarios. Our spare parts are exported to multiple overseas regions and keep long‑term stable cooperation with global construction‑machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this VOE14717725 K3V63DT‑1ZER‑9N0Y hydraulic pump fit other Volvo excavator models?
A1: Cross‑model installation is not recommended. Different pump assemblies differ in shaft spline, regulator parameters and pressure calibration values. Please double‑confirm machine model and original part number before submitting orders.

Q2: What hydraulic malfunctions can this main pump solve?
A2: It fixes failures caused by internal‑component abrasion: insufficient digging force, slow compound movements, hydraulic oil overheating, internal leakage and abnormal pump vibration or knocking noise.

Q3: Is tiered discount available for large‑volume orders?
A3: Yes, preferential pricing is offered subject to purchasing quantity. Full‑container sea freight arrangement can be supported to cut total logistics cost.

Q4: What export‑grade packaging is used for long‑distance overseas transit?
A4: Anti‑rust grease is evenly coated on all metal working surfaces. The whole pump is wrapped with waterproof shock‑absorbing PE film, then secured inside reinforced export plywood case, protecting components against collision deformation and rust formation during long‑haul ocean transportation.
