Bomba hidráulica Rexroth AP2D36L 31N1-10010 para mini-escavadora Hyundai R80-7

R80‑7 Hydraulic Pump for Hyundai Excavator spare parts 31N1‑10010 AP2D36L Axial Piston pump Aftermarket

Product Brief

This aftermarket variable axial piston pump AP2D36L, part number 31N1‑10010, acts as the central hydraulic power unit built specifically for Hyundai R80‑7 8‑ton compact excavator. It transforms engine mechanical power into regulated high‑pressure hydraulic flow to carry out core jobs including soil digging, material lifting, site grading and traveling movement, widely adopted for urban construction, landscaping projects and small‑scale demolition work. This replacement unit is highly favored by overseas repair workshops, equipment rental companies and spare‑parts distributors for on‑site pump swap and routine hydraulic system overhaul.

Working under frequent start‑stop cycles, mixed debris‑contaminated hydraulic oil and fluctuating pressure on tight job sites, the original main pump will suffer from cylinder barrel wear, piston shoe scuffing, valve plate abrasion and growing internal leakage over time. Typical machine breakdown symptoms cover weak digging thrust, sluggish boom and arm response, poor traveling performance, excessive hydraulic oil temperature rise, plus rattling noise coming from the pump housing under load. Once the main hydraulic pump fails completely, the whole excavator loses working capability, bringing about unexpected project pause and extra maintenance expenditure for equipment operators.

Our aftermarket replacement pump strictly complies with original sample standards in mounting hole layout, input shaft spline specification, oil port location and regulator setting parameters. Field technicians can finish direct fitting without any cutting, drilling or additional adapter modification, greatly cutting down machine stand‑still hours. Compared with expensive original genuine pumps with long procurement lead‑time, this hydraulic pump delivers dependable working performance and satisfies repeat bulk purchasing demands for global compact excavator spare‑parts suppliers.

Product Highlights

1. Perfect interchangeability for on‑site rapid replacement
All critical dimensions, spline teeth and port positions match the original pump entirely. Mechanics can complete pump dismount‑mount operation without secondary machining, improving overhaul efficiency for rental fleet maintenance and used‑equipment refurbishment jobs.

2. Optimized wear‑resistant construction adapting compact‑machine harsh conditions
Many low‑cost alternative pumps degrade quickly when running with aged hydraulic oil containing fine impurity particles. Our key internal friction components adopt refined heat treatment plus multi‑precision lapping craft, realizing outstanding anti‑wear and shock‑resistant capacity. It effectively extends service lifespan for R80‑7 units operating in city building sites and earth‑moving yards.

3. Rigorous bench test procedure implemented prior to shipment
Every finished hydraulic pump goes through pressure endurance testing, flow calibration and sealing leakage inspection on dedicated test equipment before packing. Factory screening eliminates defective goods, lowering rework risk for repair shops and preventing sudden equipment halt triggered by pump malfunction.

4. Budget‑friendly aftermarket solution for small‑size excavator fleet management
Genuine main pumps for Hyundai R80‑7 come with high purchase cost and unstable stock supply. Our factory‑supplied aftermarket replacement pump balances stable working property and competitive price, assisting machinery owners and service shops to control total repair expense for compact excavator fleets.

5. Diverse shipping options supporting wholesale purchasers
In‑stock goods support fast shipment upon payment confirmation. Air delivery is accessible for urgent breakdown repair orders. Sea consolidation and full‑container transport schemes help overseas bulk buyers cut comprehensive logistics expense.

Factory Production Strength

Our manufacturing base focuses on research‑development and mass production of aftermarket hydraulic replacement components for Korean‑brand small and medium excavators, covering main hydraulic pumps, travel gearboxes and swing motors. We own full production procedures: alloy steel forging, precision grinding, professional heat treatment and finished‑product hydraulic bench validation. Simulated real‑site heavy‑duty cycling tests are conducted to verify component durability matching actual urban construction and earth‑moving scenarios. Our spare parts get exported to numerous overseas territories, maintaining long‑term stable cooperative relationships with global construction machinery spare‑parts wholesalers.

Frequently Asked Customer Questions

Q1: Can this 31N1‑10010 AP2D36L hydraulic pump fit other Hyundai excavator models?
A1: Cross‑model installation is not suggested. Different pump assemblies vary in shaft spline, regulator setup and pressure calibration values. Kindly double‑check your machine model and original part number before placing orders.

Q2: What hydraulic faults can this main pump resolve?
A2: It fixes malfunctions brought by inner‑component abrasion: insufficient digging force, slow boom & arm movements, high hydraulic oil temperature, internal leakage and abnormal knocking or vibration noise from pump assembly.

Q3: Can I get tiered discount for large quantity purchase?
A3: Yes, preferential price is available based on purchasing volume. Full‑container sea freight arrangement can be supported to reduce overall logistics cost.

Q4: What kind of export‑grade package is adopted for long‑distance overseas delivery?
A4: Anti‑rust grease is coated for all metal functional surfaces. The whole hydraulic pump is wrapped by waterproof shock‑absorbing PE film, then fixed inside reinforced export plywood case, protecting components against collision deformation and rust generation during long‑haul ocean transportation.
