Product Overview

The WQ(D)-X vortex sewage and sludge submersible electric 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 semi-open impeller and volute structure. A double-end face mechanical seal plus a stuffing box 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 for static sealing. A connecting plate is added between the pump oil cylinder and the pump body to add another seal, preventing mud and sand from directly penetrating the oil cylinder, preventing mechanical seal failure, and extending service life. 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. The electric pump has a built-in temperature-type protector to prevent the electric pump from burning out.

 

Applications

This series of electric pumps are used for drainage in basements, municipal engineering, pumping high-viscosity rainwater, pumping construction site slurry, domestic sewage discharge, aquaculture sewage discharge, and other occasions.

 

Features

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

● High-precision motor, high efficiency, stable characteristics;

● Built-in temperature-type thermal protector: Prevents the 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;

● A connecting plate is added between the pump oil cylinder and the pump body to add another seal, preventing mud and sand from directly penetrating the oil cylinder, preventing mechanical seal failure, and extending service life.

 

Operating Conditions

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

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

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

● Conveying medium viscosity ≤1.3x10 ³kg/m³;

● The solid content ratio of solid particles in the medium does not exceed 3%;

● Submersion depth does not exceed 5m;

● The PH value of the conveying medium is between 4-10.
