Product Description

Product overview:
The QY series medium-sized submersible pump consists of an oil-filled vertical induction motor and a pump of different materials. It is of an upper pump structure, with the pump and the motor connected coaxially and directly. For the pump with a lift exceeding *0 m, the pressure relief check valve is provided to ensure safety in case of shutdown. Inside the motor are several thermal protection monitoring probes which can reliably protect the motor once matched with appropriate control switches; featuring high safety and reliability as well as easy installation, this pump is energy-efficient.
Product use:
It is generally applicable to mine drainage, water taking for urban tap water companies, drainage and irrigation for agricultural systems, urban construction, industrial and mining water supply and discharge, garden watering, ship bilge drainage, water supply from water towers, drainage after the rain and depression flood control.
Operating conditions:
1 The flow at the outlet of the electric pump shall not be greater than the rated value (i.e. the pump shall be used within the specified lift range);
2 The submergence depth shall not exceed 5 m, otherwise, it shall be stated when the order is placed;
3 The water temperature shall not exceed + *0 °C;
4 The pH valve shall be 5 ~ 9;
5 The volume ratio and particle size of solid impurities in water shall not be greater than 0.1% and 0.2mm respectively;
6 The power supply shall have a frequency of *0 Hz and a voltage of **0 V or **0 V. When the electric pump is in operation, the rated voltage indicated on the nameplate shall apply, with a fluctuation not exceeding ±*0%.
