Submersible Drilling Motors

Submersible motors for drilling

Submersible motors for drilling have a wide power range from 0.37 kW up to 250 kW. Indeed, submersible motors for drilling are in demand for domestic, agricultural and industrial water supply. At the same time, Pegasus submersible motors immerse themselves completely in water and consume little energy to push water.
