The working principle of the sewage and waste submersible electric pump is to drive the impeller to rotate through the motor, so that the sewage is sucked through the pump body and then discharged into the pipeline or other equipment. The impeller structure adopts a single-channel or double-channel structure, with good sewage passing capacity and no entanglement or blockage. It can be installed in an auto-coupling, fixed, or mobile manner. For more than 30 kW, auto-coupling installation and dry fixed installation can be used. The auto-coupling installation has an automatic coupling device, and the pump can automatically couple with the base pipeline along the guide rail, with the characteristics of simple and fast installation and disassembly. It is equipped with a leakage alarm, phase failure, overload, overcurrent, overheating, and other protection functions, and is equipped with a water level controller to realize automatic water level control. A heating device is installed in the motor cavity, which can effectively prevent the motor from condensing and ensure the insulation performance of the motor. It runs smoothly with low noise and vibration, and has no effect on ground personnel. Installation does not require a ground pump room; only a water collection tank needs to be built, which can save civil engineering investment. It can be equipped with direct start, Y-type start, auto-coupling step-down start, contactless soft start, and frequency conversion control device. The control system can adopt automatic control technology, and can also realize functions such as one cabinet with multiple controls and electric pump rotation starting according to user needs.

Sewage And Wastewater Submersible Pump Industry knowledge
Choosing the right submersible sewage pump is crucial for ensuring the efficient and stable operation of a wastewater treatment system. This process requires a comprehensive consideration of several core parameters, including flow rate, head, and medium characteristics. As a comprehensive pump company with over 30 years of industry experience, Tefusen (Guangde) Intelligent Technology Co., Ltd. leverages its rich product line and technical expertise to provide professional selection advice and water treatment solutions for customers with different needs.
Flow rate refers to the volume of liquid a pump can transport per unit of time, typically measured in cubic meters per hour ($$m^3/h$$) or liters per second (L/s). Accurately calculating the required flow rate is the first step in the selection process.
It is determined based on actual application needs. For example, if a factory produces 500 cubic meters of sewage per day, you need to choose a pump with a flow rate that meets or slightly exceeds this demand.
Tefusen's series of submersible pumps, such as sewage pumps and submersible pumps, come in various models and specifications, capable of meeting a wide range of flow rate demands, from small-scale domestic sewage treatment to large-scale industrial wastewater discharge.
Head is the energy required for a pump to lift liquid from the suction point to the discharge point, typically measured in meters (m). It includes the vertical height, pipe friction losses, and outlet pressure.
Head = Vertical Height + Pipe Friction Losses + Outlet Pressure. A safety margin should be included in the calculation to account for factors like pipe aging or changes in medium viscosity.
Tefusen has a professional team of engineers and technicians who can help customers accurately calculate the required head and recommend the pump model with the most suitable head curve, ensuring the pump operates at its highest efficiency point.
Medium characteristics are key factors influencing the selection of pump materials and structure. Sewage often contains solid particles, fibers, corrosive substances, and high-viscosity liquids.
If the sewage contains a large amount of solid impurities, you must choose a pump with a large-channel impeller or a cutting-type impeller to prevent clogging.
If the medium is corrosive, the pump's flow-through parts (such as the impeller and casing) need to be made of corrosion-resistant materials, such as stainless steel or special alloys.
Sewage containing long fibrous materials (like hair, textiles) requires a pump with a shredding or cutting device to avoid entanglement.
Tefusen offers multiple series of submersible pumps and sewage pumps. For different medium characteristics, we provide pump bodies with various impeller forms and materials (such as cast iron, stainless steel), ensuring stable and reliable operation even under complex working conditions.
Choosing the correct sewage and wastewater submersible pump is a rigorous engineering process. When selecting, you need to:
As a comprehensive pump company with over 30 years of history, Tefusen (Guangde) Intelligent Technology Co., Ltd. not only provides a rich product line but, more importantly, offers professional solutions. Our technical team can tailor the most suitable pump selection plan based on your specific working conditions, ensuring you get an efficient, durable, and economical pumping solution.
