Product Overview

The Q(D)X-T iron-clad submersible pump (hereinafter referred to as the electric pump) consists of three parts: a 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 pump is located below the motor and has a centrifugal impeller and volute structure. A double-end face mechanical seal plus a skeleton oil seal is used between the pump and the motor. The mechanical seal acts as a dynamic seal, and each fixed mouth seal uses an oil-resistant rubber "O" ring as a static seal. The entire pump uses stainless steel bolts. The electric pump has a built-in thermal protector to prevent the pump from burning out.

 

Features

Small size, light weight;

All-copper high-precision motor, high efficiency, heat-treated shaft, stable characteristics;

Motor built-in thermal protector: prevents the water pump from burning out during abnormal operation such as overload and jamming.

 

Operating Conditions

● The pump frequency is 50Hz, and the voltage is single-phase AC 220V, three-phase AC 380V;

● The voltage fluctuation range is ±10% of the rated value;

● Operating ambient temperature 0~40°C, transported medium temperature does not exceed +40℃;

● The solid content ratio of solid particles in the medium does not exceed 0.1%, and the particle size is no more than 0.2mm;

● Submersion depth does not exceed 5m;

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

 

Applications
