1. Before starting the powerful self-priming pump each time, there is no need to use a tank of water, which meets the needs of a wide range of users. The self-priming pump can run idle with low cost.
2. The strong self-priming pump has a short self-priming time and can absorb water even in the event of a vacuum system failure. However, the suction time can be extended to within 2-5 minutes to release water, avoiding the consequences of the entire system collapsing due to vacuum pump damage when using conventional centrifugal pump products.
3. The powerful self-priming pump can suction various types of sewage and pollutants, and has the effect of a non clogging self-priming sewage pump.
4. The vacuum system can start and stop automatically, without the need for manual supervision like the originally configured vacuum pump, which is a disadvantage of manual start and stop.

product overview

The powerful self-priming pump that can be started dry without watering has been optimized by our factory's technical engineers based on the original self-priming pump improvement. Created through innovation. It can start automatically without the need for water injection and can be automatically controlled (i.e. the vacuum pump unit will start automatically when the vacuum degree drops to a low level, and stop automatically when the vacuum degree rises to a high level, without interfering with the operation of the main pump and playing an auxiliary role). It adopts a dry abrasion resistant structure design, can run for 30 minutes, and can suck shallow water and air-water mixtures.

1、 Overview of self-priming pumps that do not require watering：

This pumpStrong self-priming pump that can start dry without wateringIt is based on the original self-priming pump and optimized by our factory's technical engineers.improve.Created through innovation. It can start automatically without the need for water injection and can be automatically controlled (i.e. when the vacuum degree drops to a low level, the vacuum pump set will start automatically, and when the vacuum degree rises to a high level, the vacuum pump set will stop automatically, without interfering with the operation of the main pump and playing an auxiliary role). It adopts a dry abrasion resistant structure design and can operate effectively30Minute, capable of absorbing shallow water and air-water mixtures. All mechanical seal components of self-priming pumps that do not require water filling should use dry grindable mechanical seal products, and additional vacuum system products can be added to the bracket between the motor and the strong self-priming pump to achieve the goal of only requiring30The effect of quickly producing water within seconds, and the vacuum system equipped with the powerful self-priming pump can achieve automatic start stop function after one click start. In conditions where the suction stroke is too high, the vacuum degree inside the self-priming pump body decreases due to the inability of the powerful self-priming pump to suction liquid. At this time, the vacuum pump will automatically start to increase the self-priming capacity of the self-priming pump. This series of self-priming pump products that do not require water filling have shown significant effects, especially when used on urban flood control and emergency pump trucks, achieving good emergency rescue results.

2、 Performance parameters of self-priming pump without water filling：

internet traffic100-6000m3/hHead lift10-120Rice can be produced, and the flow rate and head of the self-priming pump without watering can be customized according to user requirements.

After configuring the vacuum system, the self-priming height can reach8-10Meter, horizontal distance20Within meters, elongation can be customized according to user requirements.

3、 Two types of impellers can be used: stainless steel spiral impellers and stainless steel open impellers
