Denitrification stainless steel sludge reflux pumpStructure Introduction
Submersible reflux pump three-phase squirrel cage motor, 380V three-phase 50HZ, protection level IP68, stator insulation level F, direct start.
Submersible reflux pump bearings - use lifetime lubricated bearings, NSK or SKF * brand, with a service life of over 40000 hours.
Submersible reflux pump impeller - equipped with advanced axial operation three bladed impeller technology, the impeller has good self-cleaning and vibration free functions. The design of the impeller can simultaneously meet the requirements of high flow rate and low head, and form a large flow rate in the axial direction.
Submersible reflux pump sealing - using Swedish Feili submersible motor sealing technology to ensure safe and reliable sealing.
Submersible reflux pump sealing monitoring - When water enters the oil chamber, the humidity sensor in the probe side leakage system will automatically issue an alarm signal to detect it in a timely manner and prevent a second failure.
Temperature monitoring - The motor winding adopts a safe overheating protection process. Once overheating occurs due to motor overload, high medium temperature, or other reasons, the temperature sensor will promptly issue an alarm signal or automatically shut down the water pump before the temperature exceeds the allowable temperature limit.
Automatic coupling system - reflux pump with single rail automatic coupling system, ensuring fast installation, lifting and maintenance

Denitrification stainless steel sludge reflux pumpProduct Usage
Mainly used in municipal engineering, sewage treatment and environmental protection engineering industries, it can be used to discharge and transport sewage with solid particles and fibers, reflux sludge, and wastewater. The submersible reflux pump is a product independently developed based on the introduction of German submersible motor production technology. The submersible reflux pump is an equipment for mixed liquid reflux and denitrification denitrification in secondary sewage treatment plants. It can also be used in places where micro lift and high flow are required for surface drainage, irrigation, and wastewater treatment processes such as recycling.
The QHB submersible reflux pump is a new product developed based on the production technology of submersible mixers, which requires micro head in the circuit and high flow areas. This pump is a professional equipment for mixed liquid reflux, denitrification and denitrification in secondary sewage treatment plants. It can also be used for pumping purified water during ground drainage, irrigation and control of waterway systems, and for recycling or mud pumping in wastewater treatment processes.

Features:
Micro head, high flow rate, high efficiency
*The impeller has a hydraulic design structure, and the swept back blades have self-cleaning function, anti clogging, and anti winding
*Using new sealing materials, two mechanical seals made of tungsten carbide - tungsten carbide, imported bearings, and all fasteners made of stainless steel, the pump can operate safely and continuously for more than 10000 hours.
*Compact structure, simple operation and maintenance, easy installation and maintenance, long service life.
*The host adopts a cast or stainless steel pressure forming structure, with small volume, high density, corrosion resistance, and no noise
*The insulation level of the motor winding is F, and the protection level is IP68
*Factory products are equipped with protection and alarm devices for leakage, water leakage, and motor overload to ensure the safety and reliability of the products

Product Description:
Power consumption: 1.5-22KW
Impeller diameter: 400-640mm
Insulation level of submersible reflux pump: F
Submersible reflux pump material: cast all stainless steel/ordinary cast iron (can be customized according to customer requirements)

Installation system diagram:
Adopting a guide rail automatic coupling installation system: fix the guide rail on the pool wall, and install and fix the shore lifting device and the through wall outlet pipe. The sludge reflux pump can slide freely up and down along the guide rail, making installation and maintenance extremely convenient. The QWH series sludge reflux pump requires pre embedding of the wall outlet pipe, and the guide rail and lifting device are connected to the tank body with expansion bolts, without the need for pre embedded parts.
