Many users, including new practitioners of slurry pumps, often can’t distinguish the difference between submerged vertical slurry pumps and submersible slurry pumps. The names of submersible and submerged slurry pumps seem to be very similar, but there are essential differences.

　　 We would like to introduce the concepts and characteristics of the submerged vertical slurry pump and the submersible slurry pump respectively, and then compare and analyze the differences.

　　The concept and characteristics of submerged vertical slurry pump

　　 The so-called submerged slurry pump refers to a part (not all) of the slurry pump that is immersed below the page when it is working, the pump head part is under the liquid, and the motor end is above the liquid. In order to distinguish between SP and ZJL slurry pumps, SP is generally called submerged slurry pump. As shown

The so-called vertical slurry pump refers to the vertical slurry pump when the pump shaft is perpendicular to the horizontal position. Not from industry practices, submersible slurry pumps are also vertical slurry pumps, but in the industry, especially Shijiazhuang slurry pumps In the field of pumps, vertical slurry pumps generally refer to ZJL slurry pumps.

In fact, the SP submerged slurry pump and ZJL vertical slurry pump are both submerged vertical slurry pumps. The biggest feature of this type of pump is that it does not require any shaft seal. The maximum submerged depth is generally within 3 meters. After years of painstaking research, the current maximum submerged depth can reach 10 meters.
Concept and characteristics of submersible slurry pump

In terms of structure, the pump shaft and the horizontal position are generally vertical, and they belong to a vertical slurry pump. However, when it is working, the entire pump, including the motor part, is below the liquid level, so it is called "submersible ".

　　In terms of usability, the submersible slurry pump is more convenient than the submerged vertical slurry pump, and it can be directly placed in the slurry.

　　 The pump is composed of two parts: a motor and a pump, which are separated by an oil isolation chamber and a mechanical seal assembly. It is a mechatronic product. The motor and the pump share the same shaft (rotor), and the structure is compact.
The difference between submerged vertical slurry pump and submersible slurry pump

　　 1. The submerged vertical slurry pump is not completely immersed in the liquid, and the submersible slurry pump can be fully immersed or partially immersed;

　　2, the submerged vertical slurry pump needs to be fixedly installed when working, and there must be a platform for installation in the liquid surface part, and the submersible slurry pump does not need to be installed on the platform, and can be operated directly by immersing in the slurry;

　　3. The general operating depth of the submerged vertical slurry pump is 3 meters, and the maximum working depth of the submersible slurry pump can be up to 25 meters with the improvement of our company's unique technology;

　　4. The operating depth of the submerged vertical slurry pump is generally limited by the shaft length and suction pipe. The operating depth of the submersible slurry pump is mainly limited by the sealing pressure resistance, and the sealing device requirements are strict.

The above summarized and introduced the concepts, characteristics and differences between the submersible vertical slurry pump and the submersible slurry pump. I hope it will be helpful for you to understand and purchase such products. For further understanding, you can consult online QQ or dial 400 directly. .

As an emerging product, submersible slurry pumps have many advantages, especially to fill the gaps in the application conditions of traditional horizontal and vertical slurry pumps. At present, the application of submersible slurry pumps is gradually becoming more and more widely used, and the market recognition continues to increase, especially Satisfies the deep water pumping and dredging, the current depth can reach 150 meters.
