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.

2. Technical Advantages of the Original Pump
The PC130-7 is a high-production 13-ton machine. Using an Original Brand pump is critical for several reasons:
HPV Series Precision: Original pumps utilize the high-efficiency HPV piston architecture, ensuring maximum hydraulic horsepower is converted from the engine without excessive heat generation.
Pre-Calibrated Regulators: The LS (Load Sensing) and PC (Pressure Compensation) valves are factory-tuned to the PC130-7's specific engine torque curve. This ensures the machine doesn't "bog down" during heavy trenching or lifting.
Enhanced Service Life: Original units feature proprietary surface treatments on the cylinder blocks and valve plates to resist cavitation and wear under the high-pressure cycles (up to 34.3 MPa) typical of the Dash-7 series.
3. Critical Installation Protocol
To protect the warranty and longevity of a genuine 708-1L-00650, follow these expert steps:
Case Priming: MANDATORY. Fill the pump case with clean hydraulic oil through the highest drain port before starting the engine. A "dry start" will destroy the internal piston shoes in seconds.
System Decontamination: If the previous pump failed mechanically, you must flush the hydraulic tank, lines, and oil cooler. Residual metal fragments are the most common cause of failure in new pumps.
Filtration & Oil: Always replace the suction strainer and return filter with genuine Komatsu elements. Use high-quality ISO VG46 anti-wear hydraulic oil.
Air Bleeding: After installation, run at low idle for 10 minutes, cycling each cylinder slowly to its full stroke to purge air from the system.
4. Logistics & Support
Packaging: Shipped in a reinforced, moisture-protected export wooden crate.
Fitment Guarantee: We verify the input shaft spline and mounting pilot against your Machine Serial Number to ensure 100% accuracy.
Shipping: Global express via DHL, FedEx, or UPS, typically arriving in 3 to 7 business days.
