DX225 Hydraulic Main Pump | K1000698E K3V112DTP‑9N24 Axial Piston Pump | Doosan Excavator Aftermarket Replacement Parts

Product Brief

This K3V112DTP‑9N24 dual‑circuit variable axial piston pump, part number K1000698E, serves as the heart of hydraulic power system for Doosan DX225 series medium‑size excavator. Optimized for earth‑moving, municipal construction, site backfilling and quarry secondary crushing tasks, it transfers engine torque into controllable high‑pressure hydraulic flow to support bucket digging, boom lifting, slewing and travelling actions. This aftermarket replacement unit is widely procured by equipment rental firms, local repair workshops and cross‑border spare‑part distributors across Africa, Southeast Asia and Middle East for machine overhaul and component swap.

During long‑time cyclic work under mixed‑load conditions, medium‑tonnage main pumps easily suffer cylinder block scuffing, piston shoe abrasion, valve plate scratching and growing internal leakage. Visible failure signs include insufficient digging thrust, lagging combined movements, poor slope climbing performance, continuous hydraulic oil overheating, abnormal vibrating noise from pump housing and obvious power drop once machine gets hot. Sudden pump breakdown will halt construction progress and bring extra emergency repair expenditure for project owners.

Our aftermarket hydraulic pump follows OEM drawing standards for mounting flange, spline parameters, solenoid installation position and system pressure setting. No welding, cutting or extra adaptor modification is needed during field replacement, enabling direct drop‑in fit and shortening equipment downtime. As an economical substitute for costly original pump assemblies with long lead‑time, this aftermarket pump delivers steady working performance under factory wholesale price, well suited for bulk purchasing of medium excavator spare‑part merchants.

Unique Product Competitive Advantages

1. Fully dimension‑matched for Doosan DX225 hydraulic control system, not interchangeable with other excavator models
Manufactured strictly according to original installation specifications, this main pump keeps consistent oil port layout, solenoid mounting position and pressure calibration value. Well‑matched friction pairs effectively restrain internal leakage after assembly. No auxiliary processing work required for on‑site installation.
2. Upgraded friction pair craftsmanship to extend service life under medium‑duty cyclic operation
Many low‑cost replacement pumps will generate pressure decay after short running hours due to inferior raw material of internal friction pairs. Our core components adopt standardized quenching and fine‑grinding process, boosting wear resistance under frequent load shift. It helps equipment operators reduce pump replacement frequency for heavily‑used DX225 fleets.
3. Multi‑item bench inspection before shipment to avoid hidden field failure risks
Each finished hydraulic pump goes through pressure endurance test, flow calibration and tightness leakage test on professional hydraulic test bench before packing. Defective products are screened out in factory, preventing maintenance rework and unexpected site shutdown losses for end‑users.
4. Cost‑effective aftermarket solution to control medium‑size machine maintenance budget
Genuine OEM main pumps for DX225 carry high purchase cost and long delivery cycle. Our aftermarket pump achieves comparable working stability at factory direct price, cutting annual repair cost for enterprises running multiple medium excavator units.
5. Flexible global logistics arrangement for wholesale buyers
In‑stock products can be dispatched quickly upon payment confirmation. Air freight is available for urgent breakdown repair orders; consolidated sea freight and FCL service provide cost‑saving options for long‑term bulk importers.

Factory Production Strength

Our manufacturing workshop specializes in R&D and production of aftermarket hydraulic main pumps, travel motors and swing motors covering mainstream excavator brands. We own complete production workflow including alloy steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench testing. Dedicated simulation test equipment reproduces real‑world construction variable‑load working status to continuously optimize component wear resistance and pressure stability. Our hydraulic assemblies are exported to multiple overseas markets and maintain long‑term stable cooperation with global construction machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this K1000698E K3V112DTP‑9N24 main pump fit other excavator models besides Doosan DX225?
A1: Cross‑model installation is not supported. Different excavator models adopt main pumps with different flange dimension, solenoid parameters and pressure setting. Please double‑check machine model and OEM part number before placing orders.

Q2: What hydraulic failures can this main pump resolve?
A2: It solves malfunctions caused by worn pistons, scratched valve plate and damaged internal parts: weak digging power, slow compound movements, poor climbing performance, high hydraulic oil temperature, internal leakage and abnormal pump knocking noise.

Q3: Can you offer volume‑based discount for large‑quantity orders?
A3: Yes, tier‑based preferential price is offered according to purchase quantity. We can also arrange full‑container sea shipment to reduce comprehensive logistics cost.

Q4: What packaging is used for long‑distance ocean‑going transportation?
A4: Anti‑rust oil is coated on all metal surfaces. The whole pump is wrapped with waterproof shock‑proof PE film, then fixed inside reinforced export plywood case, to prevent collision deformation and moisture corrosion during long overseas transit.
