Ako odlučite kupiti opremu po niskoj cijeni, provjerite da li vi komunicirate sa stvarnim prodavateljem. Saznajte što više informacija o vlasniku opreme. Jedan od načina prijevare je da se predstave kao prava tvrtka. U slučaju sumnje, obavijestite nas o tome radi dodatne kontrole, putem obrasca za povratne informacije.
Prije nego što odlučite izvršiti kupnju, pažljivo pregledajte nekoliko prodajnih ponuda kako biste razumjeli prosječnu vrijednosti odabranog modela opreme. Ako je cijena ponude koju vam se sviđa mnogo niža od sličnih ponuda, razmislite o tome. Značajna razlika u cijeni može ukazivati na skrivene nedostatke ili pokušaj prodavača da počini prijevaru.
Nemojte kupovati proizvode čija je cijena previše različita od prosječne cijene slične opreme.
Nemojte davati suglasnost na sumnjive zaloge i plaćanje robe unaprijed. U slučaju sumnje, nemojte se bojati pojasniti pojedinosti, zatražiti dodatne fotografije i dokumente za opremu, provjerite autentičnost dokumenata i postavljajte pitanja.
Najčešći tip prijevare. Nepošteni prodavatelji mogu zatražiti određeni iznos predujma kako bi "zarezervirali" vaše pravo na kupnju opreme. Dakle, prevaranti mogu prikupiti veliki iznos i nestati, i više se ne pojavljivati.
- Prijenos pretplate na karticu
- Nemojte plaćati unaprijed bez izdavanja dokumenata koji potvrđuju postupak prijenosa novca, ako vam je tijekom komuniciranja prodavatelj postao sumljiv.
- Prijenos na račun "povjerenika"
- Takav zahtjev treba biti alarmantan, najvjerojatnije komunicirate s prevarantom.
- Prijenos na račun tvrtke s sličnim imenom
- Budite oprezni, prevaranti se mogu prikriti iza poznatih tvrtki, neznatno mijenjajući njihov naziv. Nemojte prenositi sredstva ako vam je naziv tvrtke sumnjiv.
- Zamjena vlastitih podataka u fakturi stvarne tvrtke
- Prije prijenosa, provjerite jesu li navedeni detaljie ispravni i odnose li se na navedenu tvrtku.

1. Product Overview
The AP2D12LV3RS7 is a dual-output variable displacement axial piston pump designed for compact machines requiring high power density. As the primary pump for the Bobcat 425 and 428 series, it provides the precise flow and high-pressure output needed to manage the complex hydraulic demands of a Zero Tail Swing excavator. Its integrated design ensures that the boom, arm, and bucket functions remain responsive and powerful, even during simultaneous travel, without taxing the engine's RPM.
2. Technical Specifications & OEM Part Numbers
This unit is a 100% direct "bolt-on" replacement for Bobcat factory part numbers and original manufacturer specifications.

3. Why Partner With a 13-Year Industry Expert?
Technical Precision: We specialize in AP2D series pumps and understand the exact regulator calibrations required for Bobcat machines. Our pumps restore the original "factory-feel" to your joystick controls and cycle speeds.
Rigorous Bench Testing: Every unit undergoes a comprehensive 100% hydraulic performance test. We verify volumetric efficiency, flow-to-pressure curves, and seal integrity under maximum load before shipping.
Factory-Direct Value: Access Original New or Premium OEM-spec units at competitive wholesale prices, bypassing the significant markups of local retail dealerships.
Global Rapid Logistics: Units are secured in reinforced, shock-proof export packaging. We offer express delivery via DHL, FedEx, or UPS, typically arriving in 3 to 7 business days.
4. Critical Installation & Maintenance Protocol
Case Priming (Non-Negotiable): You must fill the pump housing with clean hydraulic oil through the highest drain port before starting the engine. Running the pump "dry" for even a few seconds will cause immediate catastrophic failure of the internal components.
System Decontamination: If the previous pump failed mechanically (sending metal debris into the system), you must flush the entire hydraulic tank, main control valve, and oil cooler. Residual debris is the leading cause of failure for replacement pumps.
Filter Change: Always install a new high-efficiency hydraulic return filter and suction strainer during the pump replacement to maintain oil cleanliness and protect the precision-lapped surfaces.
5. Ordering & Professional Support
Fitment Verification: To ensure 100% accuracy, please provide your Machine Serial Number or a photo of your existing pump’s nameplate.
