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.

The HPV102GW-25A is engineered for a wide range of Zaxis models, particularly those operating in diverse global markets (including the rugged 3G series):
Standard Models: ZX200, ZX200-3
G-Series (Global/Rugged): ZX200-3G, ZX210LC-3G
Specialized Variants: * ZX210H-3G (Heavy-duty for mining/quarrying)
ZX210K-3G (Demolition/Debris handling)
Pump Identification: Often associated with Hitachi part numbers such as 9257161, 9256125, or 9260105.
2. Technical Specifications & Features
Type: Tandem Variable Displacement Axial Piston Pump.
Architecture: Dual-pump configuration providing independent flow for travel and attachment circuits.
Control Logic: Equipped with the 25A-style regulator, which is factory-tuned for the torque output of the Isuzu 4HK1 or 6BG1 engines used in these models.
Durability: Features reinforced swash plates and precision-lapped valve plates to handle continuous operating pressures of 34.3 MPa (343 bar).
3. Why Use Original Brand Parts?
The ZX200 series is the "workhorse" of many fleets. Using an Original Brand pump is essential to avoid the common pitfalls of budget alternatives:
Hydraulic "Function Drop": Original pumps ensure that when you boom up and swing simultaneously, the oil is divided exactly as intended. Non-genuine pumps often cause one function to stop or slow down significantly.
Fuel Savings: The original regulators are calibrated to destroke the pump when joysticks are in neutral. Aftermarket pumps with poor tolerances often "leak" power, causing higher fuel consumption and engine heat.
Heat Management: Original metallurgy reduces internal friction. This prevents the hydraulic oil from overheating during long shifts, which protects your seals and cylinder packings.
4. Professional Installation Protocol
To protect this high-value component, our 13-year experience dictates these mandatory steps:
Case Priming: MANDATORY. Fill the pump case with clean hydraulic oil through the highest drain port before starting the engine. Running dry for even 5 seconds will "score" the valve plate.
System Decontamination: If the previous pump failed mechanically, the hydraulic tank must be cleaned and the oil cooler flushed. Metal fragments from a failure will destroy a new pump instantly.
Filter Change: Install a new suction strainer and return filter (Genuine Hitachi 10-micron).
Air Purge: Run the engine at low idle for 10 minutes. Slowly cycle the cylinders to their limits to purge air before performing any heavy work.
5. Frequently Asked Questions (FAQ)
What is the difference between the ZX200-3 and the ZX200-3G pump?
While the internal pump mechanics (HPV102) are largely the same, the 3G (Global) series is often configured for higher-sulfur fuel environments and different cooling capacities. The pump regulators are tuned to match these specific engine performance profiles.
How do I know if my pump is an Original Brand?
Original units feature a data plate with the Hitachi or Hitachi Astemo (formerly Unisia/Nachi) branding. The casting will be clean and free of the rough textures found on low-quality clones.
How long does shipping take for a ZX200 pump?
Since this is a high-demand item, we typically have them ready for immediate dispatch. Global express shipping via DHL/FedEx/UPS usually takes 3 to 7 business days.
Does the pump come with the solenoid valves?
Yes, our Original Brand New assemblies come complete with the proportional solenoid valves and regulators pre-installed and factory-tested.
