How many meters can a common self-priming pump reach?

The problem of how many meters the suction range of the self-priming pump can reach is what the user wants to know before buying. At present, the suction range of the self-priming pump can reach 9 meters. The self-priming pump products with a suction range of 9 meters include vacuum assisted self-priming pump, domestic tap water self-priming pump and screw self-priming pump. The following is the information about these Self-priming pumps for your reference.
1. Domestic tap water self-priming pump
The commonly used domestic self-priming pump can suck within 9 meters of the suction range, and the self-priming time is within 3 minutes. The voltage of the domestic self-priming pump is 220V, the pump body is made of cast iron, and the impeller is made of copper, which can avoid the phenomenon that the cast iron impeller is rusted and causes the impeller to jam and pollute the water source, and can suck the hot water medium of about 40 degrees. Basically, this self-priming pump can only be used as a home, If it is used under other working conditions, the corrosivity of the liquid and whether the required flow head can meet your needs should be considered. If it can meet your needs, you can also choose this series of self-priming pump products.
2. Screw self-priming pump
Screw self-priming pump is also a domestic self-priming pump. Its main feature is high lift, which fills the disadvantage of low lift of ordinary domestic self-priming pump. The lift of screw self-priming pump can reach 130 meters The material is only cast iron, which is suitable for conveying clean water. The screw self-priming pump is also a self-priming pump with a suction range of 9 meters. Some merchants mark the suction range of 10-26 meters on the nameplate of the screw self-priming pump. In fact, this data refers to the horizontal distance. Many users regard it as the suction height and find that it can not be so high when they buy it back. Therefore, special attention should be paid.
3. Vacuum self-priming pump
The vacuum self-priming pump is an industrial self-priming pump. The flow of this series of self-priming pumps is more than 100 cubic meters. This series of vacuum assisted Self-priming pumps can not only be driven by motors, but also be driven by various brands of diesel engines. They can be installed on various mobile pump trucks for use as flood prevention and rescue pumps. Moreover, they can also use the open impeller structure to transport sewage media containing impurities. The pump body materials include cast iron, stainless steel, ductile iron and other metal products for users to choose, The vacuum system can be enlarged according to the user's requirements, so that the water at a distance of 9 meters can be sucked up within 30-60 seconds. The vacuum assisted self-priming pump can be allowed to idle for a short time. Therefore, the vacuum assisted self-priming pump is a kind of flood prevention and rescue pump product.
