Self-priming Pump (JET) Industry Knowledge Extension

What Is the Working Principle of Self-Priming Pump (JET)?

The working principle of self-priming pump is based on centrifugal force and vacuum principle. Here's how it works in detail:
1. When the self-priming pump is started, the motor drives the impeller to rotate at a high speed to generate centrifugal force.
2. The liquid enters the pump body through the inlet pipe, and the rotation of the impeller throws the liquid out, and at the same time throws out the air together to form a vacuum.
3. The vacuum gradually deepens until it reaches a certain level, and the liquid in the inlet pipe will be sucked in, which further increases the volume of the liquid in the pump body, thus enhancing the vacuum.
4. When the vacuum reaches a certain level, the self-priming pump can continue to operate and deliver the liquid to the desired location.

What Are the Main Components of Self-Priming Pump (JET)?

Self-priming pump (Self-priming Pump) usually consists of the following main components:
1. Pump body: the main part of the self-priming pump, including the inlet and outlet.
2. Impeller: Located inside the pump body, it is mainly used to suck and discharge liquid.
3. Water pipe: the pipe connecting the inlet and the source of the liquid, used to transport the liquid into the pump body.
4. Drain: A pipe that connects the outlet to the place where the liquid needs to be delivered, and is used to transport the liquid to the target location.
5. Seals: Used to keep the pump body airtight and prevent liquid leakage.
6. Motor: used to drive the impeller to rotate at high speed, thereby generating centrifugal force and vacuum.
7. Switch controller: used to control the start, stop and running time of the self-priming pump.

How to maintain Self-Priming Pump (JET)?

1.Regular Visual Inspections: Perform routine visual inspections of the pump, motor, and connections. Look for signs of leaks, corrosion, damage, loose fittings, and worn-out parts. Address any issues you identify promptly.
2.Clean the Pump and Area: Keep the pump and the surrounding area clean. Remove dirt, debris, and dust from the pump housing and motor to ensure proper airflow and prevent clogs.
3.Check Impeller and Diffuser: Inspect the impeller and diffuser for wear, damage, or debris buildup. The impeller is a critical component that moves water, so it must be in good condition.
4.Check Seals and Gaskets: Inspect the seals and gaskets for signs of wear, cracks, or leakage. Replace any damaged seals or gaskets to prevent water leaks.
5.Inspect Suction Pipe and Strainer: If your pump is connected to a suction pipe or has a strainer, check for clogs, debris, or blockages. Clean the strainer regularly to maintain proper water flow.
6.Lubrication: Some Self-Priming Jet Pumps may have bearings or other moving parts that require lubrication. Follow the manufacturer's recommendations for lubrication intervals and types of lubricants to use.
7.Check Electrical Components: If the pump is electrically powered, inspect the electrical connections, wiring, and plugs. Ensure that the motor is operating within the correct voltage range and that all electrical connections are secure.
8.Check Pressure Tank: If your Self-Priming Jet Pump is connected to a pressure tank, inspect the tank's pressure settings and the air charge in the tank. Adjust as needed to maintain proper pressure.
9.Replace Worn Parts: Over time, components such as seals, impellers, and gaskets may wear out. Replace these parts according to the manufacturer's recommended intervals or if you notice a decrease in pump performance.
