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 gland oil seal is used between the water pump and the motor. The mechanical seal acts as a dynamic seal, and each fixed stop seal uses an "O"-type oil-resistant rubber seal ring as a static seal. 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 thermal protector to prevent the electric pump from burning out.

 

Applications

● Living 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;

● Using a non-blocking impeller design: It can exert maximum drainage function for sewage containing solids or fibrous materials;

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

● The motor has a built-in thermal protector: to prevent the water pump from burning out due to 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.

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

● The operating ambient temperature is 0~40℃, and the temperature of the conveyed medium should not exceed +40°C;

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

● The density of the conveyed medium ≤1.3x10 ³kg/m³;

● The diving depth does not exceed 5m;
