Introduce the basic functions of the product
The self-priming pump is a common pump product with a unique self-priming function. It does not require manual water diversion when starting, can automatically pump air and water, and can quickly establish a stable water flow. The pump has a compact structure, small footprint, and is easy to install and maintain. It is suitable for the transportation of a variety of liquid media, including clean water, sewage, and some mildly corrosive liquids. It is widely used in municipal water supply and drainage, industrial wastewater treatment, agricultural irrigation and other fields. It has high working efficiency, can operate stably under different working conditions, effectively saves manpower and time costs, and provides reliable and convenient solutions for various liquid transportation operations.
Introduce the basic situation of the product
Self-priming pump is a self-priming centrifugal pump with the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. The self-priming pump can automatically pump water up without filling the suction pipe with water. Its working principle is to use the negative pressure (vacuum) formed when the pump is working to pressurize the water below the water pumping port under the action of atmospheric pressure, and then discharge it from the discharge end of the water pump.
Usage Environment
Self-priming pumps can generally operate within a certain temperature range. Usually, the medium temperature can operate normally between -20℃ and 120℃. However, this also depends on the specific self-priming pump model and material. When used in a low temperature environment, pay attention to prevent the liquid in the pump body from freezing and damaging the pump body; in a high temperature environment, pay attention to the heat dissipation of the pump body and the high temperature resistance of components such as seals.

Product Operation Guide
1. Steps for using a self-priming pump 1. Preparation before starting: First, check whether the various parts of the self-priming pump are intact, whether the fasteners are loose, and whether the rotating parts are flexible. Secondly, check whether the inlet pipeline is unobstructed and whether the outlet pipeline valve is closed. Finally, fill the pump with water to ensure that the self-priming pump can start smoothly. 2. Startup and operation: Turn on the power switch and start the self-priming pump. Observe the operation of the pump. After confirming that there is no abnormality, gradually open the outlet pipeline valve and adjust the flow rate to the required value. During operation, check the working status of the pump regularly. If any abnormality is found, it should be handled in time. 2. Precautions for using a self-priming pump 1. Safe operation: When operating a self-priming pump, be sure to comply with safety regulations to avoid accidents such as electric shock and mechanical injuries. At the same time, keep the pump room clean and tidy to prevent debris from entering the pump and affecting operation. 2. Prevent dry running: The self-priming pump must be filled with water before starting to prevent dry running and damage to the pump body. During operation, there must also be enough water in the pump. 3. Regular inspection and maintenance: Regularly inspect and maintain the self-priming pump, including replacing worn parts and cleaning the inside of the pump body. This not only prolongs the service life of the pump, but also ensures its stable performance. 4. Pay attention to temperature changes: The self-priming pump will generate heat during operation, so pay attention to the temperature changes of the pump body and motor. If the temperature is found to be too high, take measures to cool it down in time to prevent damage to the equipment.
Frequently asked questions
Difficulty starting or failure to start
Check the power supply and wires, replace the damaged power socket; contact professional maintenance personnel to repair or replace the damaged motor; clean the foreign objects in the inlet pipe and pump body.
Abnormal noise or vibration occurs during operation
Replace the broken pump shaft, overhaul or replace the worn bearings and impellers, readjust the installation position of the pump, ensure that the pump body is parallel to the ground and the pump shaft is concentric with the motor shaft.
No water or small amount of water
Reduce the suction distance or use a self-priming pump with higher power, check and repair the leaking parts, clean the debris on the impeller, adjust the motor speed or replace the motor with a suitable one.
Insufficient self-priming
Unsound foundation: If the pump is installed on an unstable foundation, it will produce loud noises due to vibration during operation. For example, if it is installed on a loose support or uneven ground.
Install appropriate exhaust device or adjust the self-priming height
