Ak sa rozhodnete kúpiť zariadenie za nízku cenu, uistite sa, že komunikujete so skutočným predajcom. Zistite čo najviac informácií o majiteľovi zariadenia. Jedným zo spôsobov podvádzania je predstaviť sa ako skutočná spoločnosť. V prípade podozrenia nás o tom informujte o ďalšej kontrole prostredníctvom formulára spätnej väzby.
Pred rozhodnutím o kúpe si pozorne prečítajte niekoľko predajných ponúk, aby ste poznali priemerné ceny zvoleného zariadenia. Ak je cena ponuky, ktorá sa vám páči, oveľa nižšia ako podobné ponuky, popremýšľajte o tom. Významný cenový rozdiel môže naznačovať skryté chyby alebo pokus predajcu o spáchanie podvodných činov.
Nekupujte výrobky, ktorých cena je príliš odlišná od priemernej ceny podobných zariadení.
Nedávajte súhlas s pochybnými prísľubmi a predplateným tovarom. V prípade pochybností sa nebojte nechať si objasniť detaily, požiadať o ďalšie fotografie a dokumenty o zariadeniach, skontrolovať pravosť dokumentov, klásť otázky.
Najčastejší typ podvodu. Neféroví predajcovia môžu požiadať o určitú čiastku preddavku na "rezerváciu" vášho práva na nákup zariadenia. Týmto spôsobom, podvodníci môžu zhromaždiť veľké množstvo peňazí a zmiznúť, a už sa im nedovoláte.
- Prevod zálohy na kartu
- Nevyplácajte zálohu bez písomného dokladu, ktorý potvrdzuje proces prevodu peňazí, ak počas komunikácie predávajúci vzbudzuje pochybnosti.
- Prevod na účet "správcu"
- Takáto žiadosť by mala byť alarmujúca, s najväčšou pravdepodobnosťou komunikujete s podvodníkom.
- Prevod na firemný účet s podobným názvom
- Buďte opatrní, podvodníci sa môžu zamaskovať ako dobre známe spoločnosti a robiť menšie zmeny názvu. Neposielajte prostriedky, ak máte pochybnosti o názve spoločnosti.
- Nahradenie vlastných údajov vo faktúre údajmi skutočnej spoločnosti
- Pred uskutočnením prevodu sa uistite, že zadané údaje sú správne a že sa týkajú určenej spoločnosti.

Product Brief
This K5V80DTP‑HNOV dual‑variable axial piston main pump with PTO interface, OEM reference number 2401‑9236B, serves as the core hydraulic power source for Doosan DH150W‑7 wheel‑type excavator. Designed for urban road reconstruction, municipal landscaping, material loading and roadside earth‑moving assignments, this wheel excavator main pump converts engine power into adjustable high‑pressure hydraulic flow to support digging, slewing, driving and multi‑action compound operation. This aftermarket pump is widely sourced by local repair garages, equipment rental operators and cross‑border spare‑part distributors across Africa, Middle East and Southeast Asia for complete hydraulic system overhaul and direct pump replacement.
Wheel excavators frequently switch between travelling mode and digging mode, the main pump endures alternating pressure impact, frequent flow adjustment and high‑temperature working environment. Common failure modes include cylinder block scuffing, piston shoe abrasion, valve plate scratch and growing internal leakage. Obvious fault manifestations consist of insufficient digging force, slow combined movements, weak wheel driving performance, continuous hydraulic oil overheating, harsh metallic knocking noise from pump housing and power drop after machine warms up. Unexpected pump breakdown will bring work suspension and generate high emergency repair expenditure for municipal construction projects.
Our aftermarket hydraulic pump strictly replicates OEM specifications for mounting flange dimension, spline parameters, PTO port layout, solenoid installation position and system pressure calibration. No cutting, drilling or extra adapter modification is required for field swap, direct drop‑in installation effectively shortens machine downtime. Compared with expensive original pump assemblies with long procurement lead‑times, this factory‑manufactured aftermarket pump delivers steady hydraulic output performance under competitive wholesale price, perfectly matching bulk‑purchase requirements for wheel excavator spare‑part merchants.
Unique Product Competitive Advantages
1. Complete parameter matching for Doosan DH150W‑7 wheel excavator hydraulic system, not universal for other machine models
Produced according to original drawing standards, this main pump maintains consistent PTO interface, oil port layout, solenoid mounting position and pressure setting values. Precisely lapped friction pairs effectively restrain internal leakage after assembly. No secondary machining work is needed for on‑site installation.
2. Reinforced friction‑pair craftsmanship coping with frequent working‑mode switching
Many low‑cost substitute pumps suffer rapid performance decay under frequent switch between digging and travelling mode. Our core internal components adopt standardized quenching and fine‑grinding processing, improving anti‑wear capacity under alternating pressure impact. It helps fleet operators cut down pump replacement frequency for heavily‑utilized DH150W‑7 wheel excavators.
3. Comprehensive bench performance testing before shipment to eliminate hidden field failure risks
Each finished hydraulic pump undergoes pressure endurance test, flow calibration and tightness leakage inspection on professional hydraulic test bench prior to packing. Defective units are filtered out inside factory, avoiding maintenance re‑work burden and unexpected jobsite shutdown losses for end‑users.
4. Cost‑effective aftermarket solution to control wheel‑excavator maintenance budget
Genuine OEM main pumps for DH150W‑7 wheel excavator carry high procurement cost and lengthy delivery cycle. Our factory‑direct aftermarket pump achieves comparable working stability and system compatibility, lowering annual overhaul expense for enterprises operating multiple wheel‑type construction machines.
5. Flexible global logistics arrangement for wholesale purchasers
In‑stock goods can be dispatched rapidly upon payment confirmation. Air freight supports urgent breakdown repair orders; consolidated sea freight and full‑container service provide cost‑saving options for long‑term bulk importers.
Factory Production Strength
Our manufacturing facility specializes in R&D and volume production of aftermarket hydraulic main pumps, travel motors and swing motors covering crawler and wheel‑type excavator mainstream brands. We own complete production workflows including alloy steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench test. Dedicated simulation test equipment reproduces real‑world alternating‑load working status of wheel excavators to continuously optimize component wear resistance and pressure stability. Our hydraulic assemblies are exported to multiple overseas markets and keep long‑term stable cooperative relationships with global construction machinery spare‑part wholesalers.
Frequently Asked Customer Questions
Q1: Can this 2401‑9236B K5V80DTP‑HNOV main pump fit excavator models other than Doosan DH150W‑7?
A1: Cross‑model installation is not supported. Different wheel excavator main pumps differ in PTO structure, flange dimension, solenoid parameters and pressure calibration values. Please double‑verify machine model and OEM part number before placing orders.
Q2: What hydraulic malfunctions can this main pump resolve?
A2: It addresses faults caused by worn pistons, scratched valve plate and damaged internal components: weak digging power, sluggish compound movements, insufficient wheel driving force, high hydraulic oil temperature, internal leakage and abnormal knocking noise of main pump.
Q3: Are tiered preferential prices available for large‑volume bulk orders?
A3: Yes, volume‑based discount policy applies according to purchase quantity. We can also arrange full‑container sea shipment to reduce comprehensive logistics costs.
Q4: What packaging measure is adopted for long‑distance ocean‑going transportation?
A4: Anti‑rust oil is evenly coated on all metal surfaces. The whole pump is wrapped by waterproof shock‑resistant PE film, then secured inside reinforced export‑grade plywood case, to prevent collision deformation and moisture corrosion during long overseas transit.
