The nozzle pump allows you to turn your drill or screwdriver into a pump for pumping liquids. The performance and efficiency of the process will depend on the power of your tool and its RPM, the power should be at least 350 watts. You simply take one hose and place it in a container of liquid, and place the other end in the container to be filled. The pump is made of stainless steel and plastic, so you should not be afraid of the appearance of rust. The main thing is to make sure that the water does not get on the screwdriver, it, like other power tools, does not like it.
