Dersom du bestemmer deg for å kjøpe utstyr til en lav pris, sørg for at du kommuniserer med den ekte selgeren. Finn ut så mye informasjon som mulig om eieren av utstyret. En måte å jukse på er å presentere deg selv som en ekte bedrift Ved mistanke, informer oss om dette for ekstra kontroll, via tilbakemeldingsskjemaet.
Før du bestemmer deg for å gjøre et kjøp, se nøye på flere salgstilbud for å forstå den gjennomsnittlige prisen på det valgte utstyret. Dersom prisen på tilbudet du liker er mye lavere enn lignende tilbud, tenk over saken. En betydelig prisforskjell kan indikere skjulte defekter eller et forsøk fra selgeren til å utføre ulovlige handlinger.
Ikke kjøp produkter der prisen er for ulik fra gjennomsnittsprisen for lignende utstyr.
Ikke gi samtykke til tvilsomme pantsettelser og forhåndsbetalte varer. Ved tvil, ikke vær redd for å oppklare detaljer, spørre om flere bilder og dokumenter for utstyret, og sjekk autentisiteten til dokumentene, still spørsmål.
Den mest vanlige typen svindel. Urimelige selgere kan be om et visst beløp i forhåndsbetaling for å «reservere» din rett til å kjøpe utstyret. På denne måten kan svindlere samle inn et stort beløp og forsvinne, og aldri ta kontakt igjen.
- Overføring av forskuddsbetaling til kortet
- Ikke utfør en forhåndsbetaling uten å ha dokumenter som bekrefter overføringen av pengene, dersom selgeren under prosessen virker tvilsom.
- Overføring til en forvaltningskonto
- En slik forespørsel er alarmerende, og mest sannsynlig kommuniserer du med en svindler.
- Overføring til en firmakonto med et lignede navn
- Vær varsom, svindlere kan utgi dem selv for å være anerkjente selskaper, ved å gjøre små endringer på navnet. Ikke overfør penger dersom selskapets navn er tvilsomt.
- Utskiftning av egne detaljer på fakturaen til et ekte selskap
- Bør du utfører overføringen, sjekk at de spesifiserte detaljene er riktige, og hvorvidt de faktisk hører til det spesifiserte selskapet.

1. OEM Part Number & Machine Compatibility
Original pump model: Kawasaki K3V63DT-HNOV tandem variable displacement axial piston pump assembly
Doosan OEM interchange part numbers: 2401-9236, 2401-9236B
Fully compatible excavator models: Daewoo Solar 130LC-V, 140LC-V, 150LC-V, 155LC-V, S150LC-7B, DH150LC-7 midi excavator
Two part numbers are supersession upgrade versions, identical mounting flange, input shaft spline, hydraulic port layout and internal hydraulic calibration; fully cross-replaceable direct bolt-on aftermarket replacement without modification
2. Core Technical Specifications
Structure type: Dual variable axial piston main pump (first stage + second stage) integrated with built-in pilot charge gear pump
Displacement per main pump: 63 cm³/rev, perfectly matched to factory load-sensing hydraulic system configuration of 13–15 ton Doosan/Daewoo midi excavator platform
Second Stage Specified Parameters
Rated working pressure (second stage): 32.4 MPa
Maximum relief pressure (second stage): 34.3 MPa
Rated operating speed (second stage): 2200 rpm
Corresponding rated input power (second stage): 68.6 kW
Overall working speed range precisely calibrated to match rated output of original DB58 engine equipped on these excavator models
Mounting bolt layout, input shaft spline dimension and hydraulic port positioning strictly comply with Doosan OEM dimensional drawings
Pump housing adopts high-strength ductile iron; internal pistons, valve plates and friction wear components use quenched wear-resistant alloy steel to improve abrasion resistance and extend overall service life
3. Internal Structure & Functional Introduction
Dual main piston pumps generate high-pressure hydraulic oil to drive boom, arm, bucket, travel and swing compound working movements
Integrated pilot gear pump supplies stable low-pressure oil for pilot control circuits and system hydraulic oil replenishment
Built-in total power matching regulator automatically adjusts total pump flow output responding to real-time load changes, preventing engine stall under heavy digging and loading conditions
Optimized tandem compact layout fits neatly inside the designated hydraulic compartment of Solar 130/140/150-V and DH150LC-7 series excavators
Built-in anti-shock relief valve reduces hydraulic impact, effectively protect pump core components during frequent compound actions
4. Product Advantages
Standard aftermarket replacement, 1:1 OEM outer casting dimensions, supporting plug-and-play installation with no modification required for hydraulic pipelines or engine mounting brackets
Every finished aftermarket pump undergoes comprehensive hydraulic bench inspection including pressure stability, flow uniformity and internal leakage testing before shipment
Complete maintenance spare parts are kept in stock, including overhaul seal kits, piston assemblies, swash plates and valve plates for separate component replacement during overhaul work
Two interchangeable OEM numbers cover six machine variants, simplify spare part ordering, stock classification and inventory management for machinery dealers and repair service centers
Standard 12-month full warranty for aftermarket unit, stable quality comparable to genuine original Kawasaki main pump
5. Packaging & Global Delivery Details
Input shaft and all hydraulic ports coated with anti-rust grease and sealed with dust-proof protective plugs
Whole pump wrapped with moisture-proof plastic film and fixed inside export-grade solid wooden crate to avoid collision and damp corrosion during long-distance sea or air transportation
In-stock aftermarket pumps can be dispatched within 3–5 working days after order confirmation
Multiple global shipping solutions available: international air express, sea LCL/FCL bulk shipment, overland truck transport for Southeast Asian markets
