Vacuum Assisted Self-Priming Pump

Key features of Vacuum Assisted Self-Priming Pump

The key features of the Vacuum Assisted Self-Priming Pump are its ability to quickly and efficiently prime itself, thanks to its vacuum assistance system, eliminating the need for manual priming. This self-priming capability makes it highly versatile and suitable for a wide range of applications, especially those with changing or difficult-to-reach water levels.

Another key feature is its durable construction, built with high-quality materials that ensure long-lasting performance. The pump's powerful motor generates strong suction force, enabling it to handle even the most challenging pumping tasks.

Moreover, the Vacuum Assisted Self-Priming Pump boasts a compact size and lightweight design, making it easy to transport and install. User-friendly controls allow for simple operation, making it suitable for both professional and DIY users.

Lastly, it features a sealing system that ensures leak-free operation, maintaining the pump's efficiency. These features combined make the Vacuum Assisted Self-Priming Pump a reliable and efficient pumping solution for various applications.

Vacuum Assisted Self-Priming Pump Working principle

The vacuum auxiliary device with vacuum auxiliary self-priming pump is mainly composed of controller, vacuum pump, water separator, liquid level sensor, exhaust valve and other parts connected by wires and pipes, and the body is installed on the self-priming pump. 

The liquid level sensor is installed in the exhaust valve, and the exhaust valve is installed at the inlet of the self-priming pump. The upper part of the exhaust valve is connected by a pipeline through the suction port of the solenoid valve and the vacuum pump with a steam separator. The liquid level sensor, the self-priming pump motor and the vacuum pump motor are connected to the control cabinet through the power line to realize the automatic control of the vacuum pump and the self-priming pump through the control cabinet key. 

The outlet of the vacuum pump is installed with a check valve, press the start button of the control cabinet, the vacuum pump starts first (it can also be made into a vacuum pump and self-priming pump to start), the air in the self-priming pump inlet pipe and the pump body is pumped out, the pump body and the inlet pipe form a vacuum negative pressure state, so that the medium is filled with the self-priming pump inlet pipe and the pump body. 

After the self-priming pump body and inlet pipe are filled with water, it will enter the exhaust valve installed above the outlet of the self-priming pump, the liquid level in the exhaust valve reaches a certain position, the liquid level sensor in the exhaust valve will transmit the signal to the control cabinet, the control cabinet will close the vacuum pump and the solenoid valve, and the self-priming pump will start to enter the normal working state. The solenoid valve and the steam separator can ensure that water does not enter the vacuum pump and cause damage to the vacuum pump. 

In any case, if the liquid in the exhaust valve drops, it proves that the suction of the self-priming pump is not enough, the level sensor will convey a signal to the control cabinet, and the control cabinet will restart the vacuum pump to assist the self-priming pump to increase the suction range. With the continuous improvement of technology, ordinary ZW self-priming sewage pump and ZX self-priming centrifugal pump can be equipped with vacuum auxiliary device to increase suction range.
