Product Overview

The Q(D)X-T iron-clad small submersible electric 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 cartridge 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 as a static seal. The entire pump uses stainless steel bolts. The electric pump has a built-in temperature protector to prevent the electric pump from burning out.

 

Applications

● Underwater pumping;

● Agricultural irrigation;

● Garden watering;

● Household water supply;

● Used to remove industrial accumulated water, construction water supply and drainage, and aquaculture pond drainage and irrigation.

 

Features

● Small size, light weight;

● All-copper high-precision motor, high efficiency, the rotating shaft is processed by heat treatment, and the characteristics are stable;

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

 

Operating Conditions

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

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

● Operating environment temperature 0~40℃, conveyed 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 not larger than 0.2mm;

● Submersion depth does not exceed 5m;

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