Product Features
Strong self-priming ability: No need to install a bottom valve, just fill it with water before the first use, and there is no need to refill it during subsequent use.
Strong ability to handle solid matter and fibers with larger particles, suitable for wastewater containing impurities.
Simple structure: The pump has a compact structure, easy maintenance, and reduces the cost of operation and maintenance.
Widely applicable: can be used in various occasions such as industry, agriculture, municipal, construction sites, etc.
Good corrosion resistance: Made of corrosion-resistant materials, suitable for transporting various acidic and alkaline liquids.
Product Structure
The structure of ZW Series Self-priming Non-clogging Sewage Pump usually includes the following main parts:
Pump body: The pump body is usually made of materials such as cast iron or stainless steel, used to accommodate and support various components of the pump.
Impeller: The impeller is a critical component of a pump, typically made of wear-resistant materials. It generates centrifugal force through rotational motion, which draws liquid into the pump and discharges it towards the outlet.
Self suction device: Self suction devices usually include an air barrier or self-priming valve, which is used to create negative pressure during startup, achieve self-priming function, and avoid pump idling during startup.
Import and export flanges: There are flange connection ports at the inlet and outlet, which facilitate connection with pipelines and enable the entry and exit of liquids.
Motor: Pumps are usually equipped with a motor to drive the impeller to rotate and provide power support.
Base: The base is usually used to support the pump body and motor, and is fixedly installed on the ground or foundation.
Liquid sealing: The pump body may also contain various sealing components and liquid sealing devices to prevent liquid leakage inside the pump body.
Product Application
Municipal sewage discharge: sewage transportation from municipal sewage treatment plants and sewage pumping stations.
Industrial wastewater treatment: discharge of sewage and wastewater from factory workshops.
Construction site drainage: transportation of drainage, mud, sand and gravel mixtures at the construction site.
Agricultural Irrigation and Drainage: Irrigation and drainage of farmland, transportation of sewage and sediment during irrigation.
Other: Drainage and sewage discharge in places such as ships and docks.
Working Principle
The working principle of ZW Series Self-priming Non-clogging Sewage Pump is based on the self-priming function of the self-priming pump. Through the special structural design inside the pump body, it can automatically suck water without the need for a bottom valve. The following is a detailed description of its working principle:
Self suction process
Water filling before initial start-up:
Before using the pump for the first time, it is necessary to fill the pump chamber with water through the filling port on the pump body. This is a prerequisite for the normal start-up of the self-priming process.
Self suction during startup:
When the pump is started, the impeller inside the pump rotates at high speed, driving the liquid to rotate. Inside the pump casing, due to the centrifugal force, the liquid inside the pump chamber is thrown around the pump casing, creating high kinetic and pressure energy.
Create a vacuum:
In the inlet area of the pump, due to the rapid discharge of liquid, a low-pressure zone is formed locally, creating a vacuum effect. At this point, external atmospheric pressure will push the liquid into the pump.
Inhalation of liquids:
Under the action of atmospheric pressure, external liquid is pushed into the pump chamber through the inlet pipe, supplementing the insufficient liquid in the pump and forming a continuous self-priming process.
Pollution discharge process:
Transporting liquids through impellers:
The liquid sucked in mixes with the existing liquid in the pump chamber and is transported to the outlet of the pump under the high-speed rotation of the impeller. At this point, the kinetic energy and pressure energy of the liquid further increase.
Discharge sewage:
The liquid is pressurized inside the pump casing and discharged through the outlet pipe, completing the entire sewage transportation process. The design of ZW Self-priming Non-clogging Sewage Pump allows it to handle wastewater containing impurities by passing through larger solid particles and fiber materials.
