What do you recommend a pump for a 15m deep well?
Hello. I ask for your advice on the well - 15 years ago, a 15-meter-long borehole with a diameter of 150 was drilled on the site. Water column 1.2, technical. For watering suits. They shook them all the time with vibration pumps. I suppose that because of this clay periodically goes.
The plot is equipped with drip irrigation (170 m). I hope that if you install a centrifugal or screw pump, the clay will disappear. When watering, the level in the well drops to 90 cm. What do you recommend? Thank.

Hello. Since you write that when water is injected from a well, its level can drop to 90 cm, it will be logical to install a screw submersible pump. These types of pumps allow you to pump water at a low level, almost at the bottom. Another very important plus of a screw pump in your case is operation in water with various impurities (for example, clay).
On account of this, clay can disappear from the water. I can’t say, it already depends on the current state of the well. If replacing the pump does not solve this problem, a coarse filter must be installed.
Regarding the technical specifications of the screw submersible pump itself. Based on these parameters, the Aquarius NVP 0.32-63U pump is enough for you with a margin. I advise you to take a pump manufactured by Promelectro, Ukraine. The optimum ratio of price and quality. The issue price is about $ 180, there are more affordable Chinese options, but I do not recommend even considering them.
