Product Overview

The A-series small vortex 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 semi-open vortex 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 moisture, prevent oxidation, and extend service life. The electric pump has a built-in temperature-type protector to prevent the electric pump from burning out.

 

Applications

● Domestic sewage discharge; rainwater accumulation discharge;

● Farmland irrigation, farmland water conservancy projects;

● Landscape gardening water use; civil engineering projects;

● Aquaculture fish pond water supply and drainage.

 

Features

● The entire series has a small weight and volume, making installation and movement convenient;

● Non-clogging impeller design: It can exert maximum drainage function for sewage containing solids or fibrous materials;

● High-precision motor, high efficiency, heat-treated shaft, stable characteristics;

● Motor built-in temperature-type thermal protector: Prevents the water pump from burning out during abnormal operation such as overload and jamming;

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

 

Operating Conditions

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

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

● Operating ambient temperature 0~40℃, the temperature of the conveyed medium should not exceed +40°C;

● The PH value of the conveyed medium is between 4 and 10;

● Density of conveyed medium ≤1.3x10 ³kg/m³;

● Submersion depth does not exceed 5m;
