Many people think that the price of a new vacuum pump unit is too expensive, so they choose to buy second-hand units. After all, both new and second-hand units can be used normally. But in fact, is this second-hand unit really worth buying? 1、 Some users buy vacuum pump units with good quality and affordable price in the second-hand market. However, it is often inevitable that there are users in the second-hand market, so when users buy second-hand units, they are very likely to be deceived and unaware. 2、 The second-hand vacuum pump unit is much cheaper than the new vacuum pump unit, which is also the main reason why users choose second-hand equipment. Because there are some brand-new second-hand units in the second-hand market, most users will be excited. However, if there are potential safety problems in the unit, once it is bought back, it can only be responsible by itself, and no one will be responsible for it. 3、 The price of second-hand units is relatively cheap, but the risk is relatively high. After all, we don't know whether there are internal problems, and there is no guarantee. However, the new units are produced by regular manufacturers, which can ensure the safety of users. At the same time, it also has after-sales guarantee. Once there is a problem, you can contact the manufacturer in time and help solve the problem to reduce unnecessary trouble. Therefore, through the analysis and comparison between the above new vacuum pump unit and the second-hand unit, it can be seen that the second-hand unit can not compare with the new unit in any aspect except that it has some advantages in price. No matter how these two units are, operation safety is very important. Therefore, Xiaobian still recommends that you not give up safety guarantee because you are greedy for a little cheap.
