Product Details
(1) Since the motor and the water pump are integrated, the on-site installation is convenient and fast, and the installation time can be saved by 95% compared with the conventional unit.
(2) Because the motor sneaked into the water, the motor has good cooling conditions, no high temperature in the pumping station, low noise, and can build an underground pumping station to maintain the ground environment, greatly simplify the geotechnical and architectural structure of the pumping station, reduce the installation area, and save the project. Cost 30-40%
(3) The submersible motor adopts double and triple mechanical seals and auxiliary sealing structure. The F grade is 155 °C insulated and the protection grade is IP68. Sealing leakage, winding and bearing temperature rise detection devices are installed in the motor.
(4) The detection signal is concentratedly fed back into the monitor of the electric control cabinet, which is convenient to operate and easy to realize automatic control and remote transmission control.
