Product Description

                                                                        Product introduction
LOS Pumps is suitable for conveying clean water with a temperature not higher than 105ºC or other liquid whose physical and chemical properties are similar to water. Mainly used in waterworks, air conditioning water recycling, building water supply, irrigation, drainage pumping stations, power plants, industrial water supply systems, fire protection systems, shipbuilding industry, such as liquid transport occasions.
It is a single-stage double-suction centrifugal pump that feeds water from both sides of the impeller. Because the pump cover and pump body are assembled with horizontal seams, it is also called a horizontal open centrifugal pump. Compared with single-stage single suction centrifugal pump, high efficiency, large flow, higher head. However, bulky, relatively bulky, generally used for fixed operations. For hilly, plateau medium-sized irrigation area, also applies to factories, mines, urban water supply and drainage and so on.
From the drive end, divided into clockwise and counterclockwise rotation.                                 

                                                                   Structural features
1. Compact structure, beautiful appearance, good stability, easy to install.

2. Smooth and optimized design of the double-suction impeller to minimize the axial force, and has excellent hydraulic performance of the leaf, and after precision casting, pump housing and impeller surface of the inner surface is extremely smooth and has significant anti-cavitation And high efficiency.

3 bearings to ensure smooth operation, low noise, long service life.

4. Seal selection mechanical seal or packing seal. 8000 hours to ensure operation without leakage.

5. Installation form Assembly without adjustment, according to the site conditions. Discrete or horizontal installation.

6. The installation of self-priming device, can automatically absorb water, that does not need to install the end of the valve, no vacuum pump, no backfill, the pump can start.

                                                                       Applications
For factories, mines, urban water supply, power plants, farmland irrigation and drainage and various water conservancy projects.

Metal corrosion in aqueous solution is an electrochemical reaction. In the metal surface to form an anode and cathode isolation of the corrosion of the cell, the metal loses electrons in solution, into a positively charged ions, which is an oxidation process that is the anode process. In the meantime, there are plenty of opportunities for the electrons to be neutralized by some kind of material in the solution when contacting the metal surface of the aqueous solution. The process of neutralizing the electrons is the reduction process, ie, the cathodic process. Common cathode processes are aerobic reduction, hydrogen release, oxidant is reduced and precious metal deposition.

With the progress of the etching process, in most cases, the cathodic or anodic processes will be blocked by the corrosion products of the solution ions, causing the diffusion to be blocked and the corrosion rate to be slower. This phenomenon is called polarization. The corrosion of the metal follows the polarization Slow down. According to statistics, wet corrosion is one of the most troublesome hazards for users in the chemical industry. Slight carelessness can damage equipment and lead to accidents or even catastrophes. Fuso blue 8510,8518 material or 2222,2223 material repair, materials, high-density molecular weight and smooth surface, can improve the ability of anti-cavitation; corrosion resistance of the material itself to make up for the weakness of the metal by weak acid corrosion and enhance the use of equipment life.
