Kawasaki K3V112DTP-HNOV-14T hydraulic pump for Doosan DH258 excavator
If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

Product Brief
The K3V112DTP‑HNOV‑14T variable axial piston main pump delivers core hydraulic power for Doosan DH258 medium‑size excavator. It converts engine torque into adjustable high‑pressure hydraulic flow to support rock excavation, earth loading, site leveling and multi‑action combined operations. This aftermarket replacement unit gains wide popularity among overseas machinery repair shops, rental fleet operators and cross‑border spare‑part dealers for worn‑out original pump replacement and complete hydraulic system refurbishment.
When working under long‑lasting dusty construction conditions with frequent impact loads, the original pump will suffer cylinder block galling, piston shoe erosion and valve plate scratching. Typical failure manifestations include insufficient digging torque, sluggish boom and arm movements, degraded traveling performance, persistently elevated hydraulic oil temperature, plus harsh pump vibration noise and obvious pressure drop under heavy digging load. Unexpected pump breakdown will interrupt construction schedules and bring extra emergency repair costs for project contractors.
Our aftermarket pump strictly follows OEM dimensional benchmarks for mounting interface, input shaft spline, regulator installation position and system pressure setting. No cutting, drilling or extra adapter modification is required during field installation, greatly shortening machine idle time. As a cost‑competitive substitute for high‑priced original assemblies with long lead‑times, this pump maintains stable hydraulic output and meets bulk purchasing requirements for global Doosan excavator spare‑part suppliers.
Unique Product Competitive Advantages
1. Full dimensional compatibility matching DH258 original hydraulic system
Manufactured referencing original technical drawings, this main pump keeps consistent shaft spline specs, oil port layout and regulator assembly dimension. High‑precision lapped friction assemblies effectively control internal leakage after assembly. No secondary machining work is needed during on‑site replacement, helping service technicians finish pump swap efficiently.
2. Upgraded friction‑pair processing for heavy‑impact construction scenarios
Many low‑cost alternative pumps suffer fast performance attenuation under repeated rock‑digging impact load. Our core internal components adopt carburizing quenching plus fine‑grinding craft to enhance wear resistance under alternating heavy load, helping fleet operators reduce pump replacement frequency for heavily‑utilized DH258 machines.
3. Complete bench performance testing before delivery to prevent on‑site sudden failure
Each finished hydraulic pump passes pressure endurance test, flow rate calibration and sealing leakage inspection on dedicated hydraulic test bench before packing. Defective units are screened out at factory side, cutting re‑work pressure for maintenance teams and avoiding unplanned job‑site downtime losses.
4. Cost‑effective aftermarket solution for 25‑ton excavator maintenance budget control
Genuine OEM pumps for DH258 carry high purchase cost and long delivery cycle. Our factory‑direct aftermarket pump provides reliable operating stability and complete system compatibility, reducing annual overhaul expenditure for customers managing multiple Doosan excavator fleets.
5. Diversified logistics support for global wholesale buyers
In‑stock goods support quick shipment after payment confirmation. Air freight is available for urgent on‑site breakdown repair orders; consolidated sea freight and full‑container solutions deliver cost‑saving options for long‑term bulk importers.
Factory Production Strength
Our production base focuses on R&D and mass‑manufacturing of aftermarket hydraulic main pumps, travel gearboxes and swing motors covering mainstream Korean‑brand excavator models. We own complete production procedures: alloy steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench test. Professional simulation test equipment reproduces real‑world heavy‑variable‑load working state of medium‑large excavators to verify component durability. Our hydraulic spare parts are exported to multiple overseas regions and maintain long‑term stable cooperation with global construction machinery spare‑part wholesalers.
Frequently Asked Customer Questions
Q1: Can this K3V112DTP‑HNOV‑14T main pump fit other Doosan excavator models besides DH258?
A1: Cross‑model fitment is not recommended. Different main pumps vary in shaft spline, regulator parameters and pressure calibration values. Please double‑verify your machine model and original part number before submitting orders.
Q2: What hydraulic faults can this main pump fix?
A2: It resolves failures caused by worn pistons, scratched valve plate and damaged inner assemblies: weak digging power, slow cylinder response, high hydraulic oil temperature, internal leakage and abnormal vibration or knocking noise coming from main pump.
Q3: Am I eligible for quantity discount for bulk orders?
A3: Yes, tiered favorable pricing is offered according to purchase volume. Full‑container sea shipment can be arranged to lower comprehensive logistics expenses.
Q4: What packaging is adopted for long‑distance overseas shipment?
A4: Anti‑rust oil is evenly applied on all metal surfaces. The whole pump is wrapped with waterproof shock‑absorbing PE film, then fixed inside reinforced export‑grade plywood case to avoid collision deformation and moisture corrosion during long‑haul ocean transit.
