Če se odločite za nakup opreme po nizki ceni, se prepričajte, da ste komunicirati z resničnim prodajalcem. Izvedite čim več informacij o lastniku opreme. Eden od načinov goljufanja se je predstavljati za resnično podjetje. V primeru suma o tem obvestite nas za dodatno kontrolo preko obrazca za povratne informacije.
Preden se odločite za nakup natančno preglejte več prodajnih ponudb, da boste razumeli povprečno ceno izbrane opreme. Če je cena ponudbe, ki vam je všeč, veliko nižja od podobnih ponudb, pomislite na to. Pomembna razlika v ceni lahko kaže na skrite napake ali pa na poskus prodajalca na goljufivo ravnanje.
Ne kupujte izdelkov, katerih cena je preveč drugačna od povprečne cene za podobno opremo.
Ne dajajte soglasja za dvomljive obljube in predplačane izdelke. V primeru dvoma se nikar ne bojte pojasniti podrobnosti, zahtevajte dodatne fotografije in dokumente za opremo, preverite pristnost dokumentov in postavite vprašanja.
Gre za najpogostejšo vrsto goljufije. Nepošteni prodajalci lahko zahtevajo določen znesek - predplačilo - torej "rezervacijo" vaše pravice do nakupa opreme. Tako goljufi lahko zberejo veliko količino denarja in izginejo, mi pa ne moremo več stopiti z njimi v stik.
- Prenos predplačila na kartico
- Ne opravite predplačila brez dokumentov, ki potrjujejo postopek prenosa denarja, če prodajalec v sporočilu izraža dvom.
- Prenos na račun "skrbnika" (agenta)
- Takšna zahteva bi morala biti zaskrbljujoča, verjetno komunicirate z goljufi.
- Prenos na račun podjetja s podobnim imenom
- Bodite previdni. Goljufi se lahko prikrijejo kot znane družbe, saj opravijo manjše spremembe imena. Ne prenesite sredstev, če je ime podjetja sumljivo.
- Zamenjava lastnih podatkov na računu resničnega podjetja
- Pred prenosom poskrbite, da so navedeni podatki pravilni in da se nanašajo točno na določeno podjetje.

2. Technical Specifications
Type: Tandem Variable Displacement Axial Piston Pump
Displacement: 145 cc/rev x 2
Max Operating Pressure: 34.3 MPa (343 bar)
Power Boost Pressure: 36.3 MPa (363 bar)
System Integration: Calibrated for HIOS III hydraulics and Isuzu 6HK1 engine torque curves.
3. Key Installation Protocols
Case Priming: Fill the pump housing completely with clean hydraulic oil via the highest case drain port BEFORE engine startup to prevent dry-run damage.
System Flush: If replacing a mechanically failed pump, thoroughly flush the hydraulic tank, main control valve, and oil cooler lines to remove residual debris.
Filtration: Replace the suction strainer, pilot filter, and high-pressure return elements with genuine 10-micron filters. Use clean ISO VG46 oil.
Air Purge: Run the engine at low idle for 10 minutes post-installation. Cycle all cylinders slowly to their limits without load to bleed trapped air.
4. Shipping & Logistics
Packaging: Secured inside a heavy-duty, steel-banded export wooden crate with moisture barriers and protective port plugs.
Transit Time: Global express air freight via DHL/FedEx/UPS typically delivers within 3 to 7 business days.
5. Critical Installation Requirements
Case Priming (Mandatory)
Before starting the engine, manually fill the pump housing with clean hydraulic oil through the highest case drain port. Running an axial piston pump dry for even a few seconds will instantly destroy the piston shoes and swash plate.
Complete Hydraulic Decontamination
If the previous pump suffered a mechanical breakdown, you must flush the hydraulic tank, clean the main control valve bank, and thoroughly flush the oil cooler lines. Residual metal debris will act like liquid sandpaper and destroy the new pump.
Filtration & Fluid Upgrade
Always replace the suction strainer, the pilot filter, and the high-pressure return elements with genuine 10-micron filters. Refill the system using only clean, high-grade ISO VG46 anti-wear hydraulic fluid.
Air Purge Routine
On initial startup, run the engine at a low idle for 10 minutes. Slowly cycle all cylinder functions to their full extension limits without any load to safely bleed trapped air pockets back into the reservoir.
6. Frequently Asked Questions (FAQ)
Q: Are the pumps for the ZX330-3 and the heavy-duty ZX350H-3 exactly the same?
A: Mechanically, the pump body frame (HPV145HW) is identical. However, depending on the specific machine application (such as the "H" heavy-duty mining spec or "K" demolition spec), the regulator settings or pressure relief limits may be configured differently. Always provide your Machine Serial Number to ensure the factory regulator calibration matches your application.
Q: What are the primary indicators that my HPV145HW pump is failing?
A: The most common symptoms include a noticeable increase in overall cycle times (sluggish performance across all functions), the engine loading down or stalling when joysticks are fully deflected, or a loud, high-pitched whining noise (cavitation or internal component wear) coming from the pump compartment.
Q: How is a pump of this size packaged and shipped safely?
A: Due to the substantial weight of the 145cc tandem assembly, the pump is treated with rust-preventative oil, capped with heavy-duty port plugs, wrapped in a moisture barrier, and securely bolted inside a reinforced, steel-banded export wooden crate to prevent any movement or impact damage during transit.
Q: Does the pump come with the regulators pre-installed?
A: Yes, our Original Brand New assemblies come complete with the pre-calibrated regulators and proportional solenoid valves factory-tested and ready for drop-in installation.
