300qj submersible pump from the multi-stage pump, motor and water chamber, seals and other major components. Three-phase use of oil-type motor, good quality, low noise, reasonable structure, sophisticated technology. It is characterized by: because the head without limit of the deadline, as long as the maximum range within the work can be, and the high head, high efficiency, efficient area wide, is the ordinary screw pump ten to several times, so widely applicable In the long-distance water supply irrigation, aquaculture efficient oxygen, deep wells water, urban and rural water pressurization, mine water supply and food and chemical industry transport furcass and non-corrosive chemical liquid.
200QJ series submersible pump is a centrifugal water pump, the flow range of 10-80 cubic meters / hour, the range of 11-600 meters, mainly from the deep wells, reservoirs and other water projects, widely used in farmland Irrigation, urban industrial and mining enterprises to the water supply and drainage, plateau, mountain water consumption. With a simple structure, easy installation and maintenance, energy efficient and so on.
