Product overview
QY series oil-filled submersible electric pump (hereinafter referred to as "electric pump") is composed of three parts: pump, seal and motor. The pump is located at the upper part of the electric pump, and the centrifugal, mixed-flow or axial-flow motor is located at the lower part of the electric pump, which is oil-filled three-phase asynchronous motor. A mechanical seal is used between the pump and the motor, and a "0" oil-resistant rubber seal ring is used for static sealing at each fixed stop seal.

Conditions of use
The electric pump should be able to work continuously under the following conditions:
1, the medium temperature does not exceed +40℃;
2, the PH value of the medium is between 6.5 and 8.5;
3, the volume ratio of solid impurities in the medium does not exceed 0.1%, the particle size is not greater than 0.2mm;
4, the rated frequency of AC power supply is 50HZ, the rated voltage is three-phase 380V voltage fluctuation
The range is ±10% of the rated value;
5, the diving depth is not more than 5m.
