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.

Hydraulic pumps act as core power sources in hydraulic systems, mainly converting mechanical input (from engines or motors) into hydraulic energy. Their working principle relies on volume change: internal components like pistons or gears move to expand the inlet cavity, forming low pressure to suck in fluid from reservoirs. Then, they compress the cavity to raise fluid pressure, pushing it through outlets into system pipelines.
Their roles are vital. First, they supply stable high-pressure fluid to drive actuators (cylinders or motors), enabling machinery movements such as excavator arm lifting. Second, they regulate fluid flow and pressure via matching valves, adapting to different load needs. Third, they ensure efficient energy transfer—minimizing loss to keep equipment running smoothly. Without them, heavy machinery like loaders or presses would lose the power to perform heavy-duty tasks, making them indispensable in engineering fields.
