Common Types of Sewage Pumps
There are many types of common sewage pumps, which can be divided into many categories according to different classification standards. The following are some common types of sewage pumps and their characteristics:
1. Classification by purpose and working principle
Sewage pump:
Purpose: used to transport sewage from one place to another, commonly used in urban sewage, industrial wastewater treatment and other fields.
Sewage lifting pump:
Purpose: used to lift sewage from low to high, especially suitable for sewage discharge in underground parking lots, underground shopping malls and other places.
Sewage deep well pump:
Purpose: used to lift sewage from deep wells to the ground, commonly used in rural sewage treatment and other fields.
Sewage submersible pump (submersible sewage pump, such as WQ series):
Features: It can work submerged in water, with a relatively simple structure, widely used in urban sewage treatment plants, water plants, municipal engineering, construction sites, residential areas, hospitals, hotels, high-rise building sewage discharge, subways, basements, civil air defense system drainage stations, enterprise unit wastewater discharge and other scenes. At the same time, it is also suitable for chemical, petroleum, pharmaceutical, mining, papermaking, power plants and other industries, especially for conveying sewage and dirt with particles and fibers.
2. Classification by structure and characteristics
Centrifugal sewage pump:
Working principle: It uses centrifugal force to discharge liquid from the center to the outside. It is a common type of sewage pump.
Cut-type sewage pump:
Features: It can cut the sewage into small particles and is suitable for treating sewage containing large particles of sewage.
3. Classification by material and characteristics
Stainless steel sewage pump:
Advantages: Corrosion-resistant, high-temperature-resistant, easy to clean, commonly used in food, pharmaceutical and other industries. When choosing, the pH value and particle diameter of the water quality should also be considered to select the appropriate stainless steel material (such as 304, 316 or 316L).
Cast iron sewage pump:
Advantages: Simple structure, low price, widely used in urban sewage, industrial wastewater treatment and other fields.
Fiberglass sewage pump:
Advantages: Light weight, corrosion resistance, suitable for the discharge of corrosive liquids such as seawater and sewage.
4. Other types
Self-priming sewage pump (such as ZW non-clogging sewage pump):
Features: It has self-priming ability and can be started and pumped without water diversion. It is particularly suitable for occasions where self-priming ability is required. At the same time, its double-blade impeller structure and new mechanical seal design improve the passing capacity of sewage and the operating reliability of the pump.
Vertical sewage pump (such as LW stainless steel vertical sewage pump):
Features: The unique impeller structure and new mechanical seal can effectively transport sewage containing solids and long fibers. Its single-channel or double-channel impeller form makes the pump have the characteristics of high efficiency and smooth operation.
Automatic mixing sewage pump (such as JYWQ automatic mixing sewage pump):
Features: Equipped with an automatic mixing device, it can stir the sediment in the pool into suspended matter and then suck it into the impeller for discharge, achieving the effect of dredging. At the same time, its unique double-channel non-clogging impeller structure and double-end mechanical seal design improve the flow capacity and sewage discharge capacity of sewage and ensure the safe and reliable operation of the pump.
