Product Overview

The Q(D)X-B stainless steel submersible pump (hereinafter referred to as the electric pump) consists of three parts: a water pump, a seal, and a motor. The motor is located at the top of the electric pump and is a single-phase or three-phase asynchronous motor. The water pump is located below the motor and has a centrifugal impeller and volute structure. A double-end face mechanical seal plus a stuffing box oil seal is used between the water pump and the motor. The mechanical seal acts as a dynamic seal, and each fixed mouth seal uses an oil-resistant rubber "O" ring for static sealing. The entire pump uses stainless steel bolts, and the pump casing is electrophoretically treated to effectively isolate air and water, prevent oxidation, and extend service life.

 

Applications

This series of electric pumps are widely used in seawater aquaculture aeration and drainage, well water pumping, agricultural irrigation, garden watering, spraying, household water supply, and other water supply and drainage occasions.

 

Features

● Small size, light weight, easy installation and movement;

● The motor adopts a new sealing structure, which has good sealing performance and ensures that it will not be damaged during assembly.

● Stainless steel material, wear-resistant, corrosion-resistant, beautiful appearance, compact structure;

● Uses stainless steel connecting shaft, PPO impeller and cast iron impeller for corrosion resistance;

● Standard built-in brand overload thermal protector, effectively preventing motor burnout;

 

Operating Conditions

● The electric pump operates continuously and normally under the following conditions.

● The temperature of the water source is less than 40°C.

● The PH value of the medium is between 6.5 and 8.5.

● The power frequency is 50Hz, the voltage is 220V single-phase AC, 380V three-phase AC, and the voltage fluctuation range is ±10% of the rated value.

● The water contains no more than 0.1% solid impurities, particles are no larger than 0.2mm, and the submersion depth does not exceed 5m.
