reflux pump introduction

---

The submersible reflux pump(also called axial pump) is a new type of product developed based on the production technology of submersible mixers, also known as a wall pump. This pump is a specialized equipment for mixed liquid reflux and denitrification in sewage treatment plants, and can also be used for extracting purified water during surface drainage; Irrigation and control waterway systems; Low head and high flow places are required in the recycling or mud suction circuit during wastewater treatment.

Structure Introduction

Specially designed device components and equipment spare parts enable the sludge reflux pump to achieve good performance.

Cable: watertight cable;

Junction box: The junction box is completely enclosed and isolated from the surrounding liquid and stator box;

Motor: 50Hz squirrel cage 3-phase submersible asynchronous motor, Class F insulation, protection level IP68. The motor is cooled by the surrounding medium;

Shaft: The shaft of the motor is made of stainless steel material, and the rotor is subjected to dynamic balance test;

Sealing: The static seal is an O-ring seal. The shaft seal is a mechanical seal that isolates the oil chamber from the surrounding medium;

Bearings: Brand bearings are used, with a designed service life of over 100000 hours;

Oil chamber: Oil is used to lubricate and cool the friction pairs of mechanical seals, and to isolate the penetrating fluid;

Impeller: The impeller has three blades, which are wide and thin, with a smooth surface that is swept back, efficient and unobstructed operation, and has self-cleaning function;

Cone tube: The purpose of a cone tube is to form a good flow state;

Discharge joint: The discharge joint is used to fix the cone pipe on the outlet pipe;

Guiding device: The guiding device consists of two pipes (conduits) and an upper conduit clamp.
