The horizontal slurry pump is named according to the placement form of the slurry pump, which means that the pump body is placed horizontally. Horizontal slurry pumps are widely used in slurry transportation in mining, metallurgy, chemical, and other industries. The following lists the structural characteristics of the horizontal slurry pump and five advantages compared to other similar pumps.

Structural characteristics of horizontal slurry pump

1. The casing of the pump adopts a vertical split structure. Installation holes are not designed on the pump casing, which is convenient for installation and maintenance.

2. The sealing device at the inlet of the impeller adopts the form of the auxiliary blade and angle type fork seal, and the sealing effect is good.

3. The shaft seal system adopts the dynamic seal form in which the back vane, the auxiliary impeller, and the packing cooperate with each other. The sealing effect is reliable, and there is basically no leakage.

4. The gap between the impeller and the guard plate can be easily adjusted through the bolts on the bracket, so that the pump can run in the high-efficiency area.

Five advantages of horizontal slurry pump

1. High efficiency and energy saving

Compared with other similar pumps, the efficiency of the horizontal slurry pump is increased by more than 8%. The power plant test shows that the running current is stable and the energy-saving effect is obvious. The original pump current is 62~65A, and now it is 47~50A, saving 1.48 million kw·h of electricity throughout the year.

2. Wear-resistant parts

The design of the flow passage parts of the horizontal slurry pump is reasonable, and new wear-resistant alloy materials are used. The actual test by the user shows that the life of the overcurrent parts of this series of pumps is generally more than 3 times that of the original pump.

3. Novel form of shaft seal

The shaft seal of the pump is a dynamic seal combined with the back vane, the auxiliary impeller, and the packing. Shaft seal water and cooling water are not required. Not only saves water, but also has no leakage.

4. Reasonable structure

Small vibration, low noise, convenient use and maintenance, and long service life, greatly reduce the amount of maintenance.

5. Significant economic benefits

According to the calculation of the power plant, the annual power saving value of each wear-resistant slurry pump is 148,000 yuan, the water-saving value is 30,000 yuan, the oil saving value is 5,000 yuan, and the production and maintenance cost is saved by more than 80,000 yuan, totaling more than 260,000 yuan.
