Nachi PVD-0B-24P-6G3 hydraulic pump for Kubota KX25 mini 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 PVD‑0B‑24P‑6G3 variable axial piston pump acts as the heart of hydraulic power for KX25 mini excavator. It transfers engine rotational torque into controllable hydraulic pressure to fulfill digging, lifting, track travelling and combined multi‑action operations on small‑scale job‑sites including landscaping, indoor demolition and narrow‑space municipal renovation. This aftermarket replacement unit is widely sourced by overseas repair workshops, equipment rental stores and spare‑part distributors for worn‑out original pump replacement.
When the original hydraulic pump suffers from piston shoe abrasion, valve plate scuffing and increased inner leakage, the machine will show obvious malfunctions: insufficient digging force, slow cylinder response, abnormal buzzing noise and rising hydraulic oil temperature. Sudden pump failure will halt field work and bring unexpected repair expense.
Our aftermarket pump strictly follows OEM dimensional benchmarks for mounting flange, input shaft spline, control valve installation location and pressure setup. Field installation can be finished without cutting, drilling or extra adapters, greatly cutting down machine downtime. Compared with high‑priced original units with long lead times, this aftermarket pump delivers stable hydraulic performance and meets bulk purchasing demand for global mini excavator part suppliers.
Unique Product Competitive Advantages
1. Strict dimensional compatibility for KX25 mini excavator hydraulic system
Produced referring to original drawing standards, this main pump keeps identical shaft spline specs, oil port layout and control valve assembly dimension. Precisely lapped friction assemblies effectively suppress inner leakage after assembly. No secondary machining work is needed during on‑site fitting.
2. Reinforced friction‑pair craft for mini‑machine cyclic load scenarios
Many low‑cost substitute pumps degrade rapidly under repeated compound movements. Our core internal components adopt carburizing quenching plus fine‑grinding processing to boost wear resistance under alternating load. It helps rental‑fleet clients lower pump replacement frequency for heavily operated KX25 units.
3. Full‑set bench testing before shipment to avoid unexpected field breakdown
Every finished hydraulic pump will go through pressure endurance test, flow calibration and sealing leakage inspection on dedicated hydraulic test bench before packing. Defective items are screened inside factory, easing maintenance technicians’ rework burden and avoiding unplanned site downtime.
4. Budget‑friendly aftermarket solution for small excavator maintenance cost control
Genuine OEM pumps for KX25 come with high purchase cost and long delivery cycle. Our factory‑direct aftermarket pump delivers reliable running stability and system compatibility, cutting annual overhaul cost for customers managing multiple compact excavator fleets.
5. Flexible logistics solutions for worldwide wholesale purchasers
In‑stock goods support fast dispatch upon payment confirmation. Air freight is available for urgent breakdown repair orders; consolidated sea freight and full‑container options provide cost‑saving choices 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 mini and medium excavator models. We own complete production procedures: alloy steel forging, precision grinding, professional heat treatment and finished‑product hydraulic bench test. Professional simulation equipment reproduces real‑site variable‑load working conditions of compact excavators to verify component stability. Our hydraulic spare parts are exported to multiple overseas regions and maintain long‑term cooperative relationships with global construction machinery spare‑part wholesalers.
Frequently Asked Customer Questions
Q1: Can this PVD‑0B‑24P‑6G3 main pump fit other mini excavator models apart from KX25?
A1: Cross‑model application is not recommended. Different main pumps differ in shaft spline, control valve parameters and pressure calibration values. Please double‑confirm machine model and original part number before submitting orders.
Q2: What kind of hydraulic faults can this main pump resolve?
A2: It fixes malfunctions triggered by worn pistons, scratched valve plate and damaged internal assemblies: weak digging capacity, sluggish cylinder movements, over‑heated hydraulic oil, inner leakage and abnormal humming or knocking noise generated by main pump.
Q3: Can I get volume‑based discount for large‑quantity orders?
A3: Yes, tiered favorable price is offered according to purchase quantity. Full‑container sea shipment can be arranged to lower overall logistics expenditure.
Q4: What packaging will be adopted for long‑distance overseas delivery?
A4: Anti‑rust oil is evenly coated for all metal surfaces. The whole pump is wrapped by waterproof shock‑resistant PE film, then fixed inside reinforced export‑grade plywood case, preventing collision deformation and moisture corrosion during long‑haul transportation.
