Vacuum assisted self priming centrifugal pump

1、 Overview of Vacuum Assisted Self priming Centrifugal Pump Products
Vacuum assisted self priming centrifugal pumps are currently widely used in vacuum assisted self priming centrifugal pump trucks. Due to the slow self priming time and low self priming height when using conventional self priming centrifugal pumps on pump trucks, vacuum assisted systems have been added to self priming centrifugal pump trucks in the pump industry. Vacuum self priming centrifugal pumps have been updated and replaced with several generations of vacuum assisted self priming centrifugal pump products, The new model belongs to a vacuum assisted self priming centrifugal pump product that can self suck up to 8 meters without vacuum assistance. On the basis of the vacuum assisted self priming centrifugal pump product, a vacuum assisted self priming centrifugal pump product with a vacuum assistance system has been added. In the case of a malfunction in the vacuum assisted system, this series can also self suck up to a height of 8 meters and 8 meters in 5 minutes. In the past, when the vacuum assisted self priming centrifugal pump had a malfunction in the vacuum assisted system, the self priming height of the self priming centrifugal pump was only about 4-5 meters Moreover, the self priming time is relatively slow and cannot achieve the effect of emergency rescue when used in flood prevention and rescue operations. Therefore, the newly developed vacuum assisted self priming centrifugal pump will be a more suitable product for the use of vacuum assisted self priming centrifugal pump trucks.
2、 Main characteristics of vacuum assisted self priming centrifugal pump
1. The 2019 vacuum assisted self priming centrifugal pump can achieve a self priming height of up to 8 meters without a vacuum pump.
2. The newly developed open impeller of vacuum assisted centrifugal pump has good anti clogging effect, and the diameter of solid particles is much larger than that of previous self priming centrifugal pumps. The 150 caliber can pass through 75mm.
3. The vacuum assisted self priming centrifugal pump can reach a self priming height of 9 meters without cavitation, and the self priming horizontal distance can reach 150 meters.
4. The impellers of vacuum assisted self priming centrifugal pumps are all made of stainless steel material, ensuring a longer service life. The pump body is made of ductile iron material, and the pump shaft is made of 3Cr13 material.
5. The vacuum assisted self priming centrifugal pump motor can use a permanent magnet energy-saving motor, and the flow head can be adjusted according to user needs to make the motor speed more energy-saving and meet the requirements of China's energy-saving product certification.
6. The diesel engine matched with the vacuum assisted self priming centrifugal pump truck can be selected from domestic or imported brands according to user needs, and the diesel engine speed can be 1500, 1800, and 3000r/min for different requirements.
7. The bottom of the vacuum assisted centrifugal pump body is equipped with an independent drain valve for draining water after use. And there is an independent maintenance port with a diameter of 150mm. During maintenance, the pump body and motor can be repaired without disassembling, which is convenient and fast.
