Knowledge about pressure ratio of gas booster pump

The boost ratio is an important factor in determining the output pressure of a pump. Customers can choose the boost ratio they need according to their pressure requirements. Generally speaking, the boost ratio multiplied by the driving air pressure (i.e. the pressure of the air compressor) ≤ 8 bar equals the output pressure. Now let's introduce how to choose the specific boost ratio

Example: The current pressure of the air source in a certain company's workshop is 6 bar, which can meet the production needs of most equipment. However, the company requires a pressure of 10 bar for purchasing one piece of equipment. If a large air compressor is purchased, due to its high cost and loud noise, a local gas booster pump needs to be purchased for boosting.

Solution: It is recommended that the customer use a 2:1 Feentor gas booster pump, with an output pressure equal to 12 bar by multiplying the customer's factory pressure by 2. The 12 bar pressure can be buffered in a gas storage cylinder and then depressurized for use. This is a very typical basic case

For example, a valve manufacturer conducts a static pressure test on a valve using water and oil as the medium; We need to increase the pressure to 20 bar for pressure testing, and the on-site driving pressure is 8 bar;

Solution: It is recommended that the customer use a liquid booster pump with a boost ratio of 4:1. The gas source pressure regulating valve at the drive port of the liquid booster pump is used to adjust the driving pressure at the customer's site to 5 bar. Therefore, the output liquid pressure can be maintained at 20 bar and then tested

The above is the selection of the boost ratio between gas booster pump and liquid booster pump. In fact, when choosing the boost ratio, there should be a margin to better select the suitable pneumatic boost product for customers. That's all for now.
