Horizontal Slurry Pump VS Vertical Slurry Pump

Slurry pump is a kind of centrifugal pump, used to transport the mixture of water and solid particles, such as ore slurry, ore sand, mud, etc. Slurry pumps can be divided into vertical slurry pumps and horizontal slurry pumps.

This article talks about the characteristics, differences, advantages and disadvantages of horizontal slurry pumps and vertical slurry pumps.

Horizontal Slurry Pump


The horizontal slurry pump adopts mechanical seals, and most parts can be interchanged to increase the service life. Simple operation and convenient maintenance; In addition, the horizontal slurry pump has low operating noise and low vibration; it is strong and durable, has a long service life, has a spacious flow path and has good corrosion resistance.


It is used for conveying ore pulp or other heavy medium liquid weighting agent, the concentration of ore pulp is as large as 50%. It is an indispensable equipment for transporting ore, silt and ash in metallurgy, mining, coal, construction and other departments. It is mainly used for conveying concentrate slurry and discharging tailings in concentrators. It can also be used for conveying media in coal preparation plants, conveying high-temperature crystalline slurry in aluminum plants, and conveying slurry in cement plants.

Product principle

The horizontal slurry pump is driven by a motor to transfer via a V-belt pulley, and the impeller under the rigid shaft is adjusted and rotated in a clockwise direction. The slurry enters the pump chamber through the feed port, and the slurry is output under the action of the impeller.

Vertical Slurry Pump


The vertical slurry pump adopts the auxiliary impeller to reduce the back pressure of the impeller and extend the life of the seal. At the same time, the flow parts are made of white wear-resistant cast iron, which is resistant to abrasion. The flow parts and inner lining of the pump are made of wear-resistant and corrosion-resistant rubber to make the life longer. In addition, the vertical slurry pump has the characteristics of light weight and easy installation.


The vertical slurry pump consists of a pump body, a bearing seat, and a solid connection impeller at the lower end of the vertical shaft that rotates in a rolling bearing. The two ends of the bearing seat are compressed by glands and rolling bearings, and the lubricating oil of the bearing must be sealed to prevent leakage. The pump body is equipped with a motor support and a motor. The impeller rotates in the pump chamber through the V-belt rotating, and the slurry is compressed by the pressure of the impeller. Out. In order to prevent ore from penetrating into the bearing, a centrifugal wheel is installed on the main shaft.


Vertical slurry pumps are mainly used to transport mud, mortar, ore slurry and similar liquids containing suspended solid particles. Such as oil drilling mud purification system, concentrator conveying concentrate slurry, tailings, slime, etc. It is suitable for conveying abrasive or corrosive slurries in various mining, chemical, electric power, building materials, agriculture and other industries.


After reading their respective introductions, let’s summarize their differences:

Vertical slurry pumps, also called submerged slurry pumps, are long-axis submersible pumps that can be immersed in the liquid to work, and can work normally under conditions of insufficient suction, and they can be idling. It is suitable for conveying the slurry in the pond below the ground, because the horizontal pump usually has no suction lift, and it cannot be conveyed to the pond dug under the ground.

The horizontal slurry pump is a horizontal pump installed on the ground. It usually needs an inverted installation so that the slurry can automatically flow into the pump cavity without opening the pump.

1. Starting method

The vertical submerged slurry pump does not need to be started up by reverse irrigation. The impeller is located underwater and the suction performance is better. Therefore, it can use a higher speed and can work normally under the conditions of insufficient suction; the horizontal slurry pump needs to be reversed. installation.

2. Installation area

The vertical submersible slurry pump has a small footprint and is light in weight. If the unit of the slurry pump uses a limited area, the vertical submerged slurry pump can be selected appropriately; the horizontal slurry pump has a large area and needs to be installed. Very large area.

3. Structural features

The vertical submersible slurry pump has a single pump shell structure; the horizontal slurry pumps mostly have a double pump shell structure.

4. Maintenance

The working part of the vertical submerged slurry pump is below the liquid level, which is inconvenient to maintain; the horizontal slurry pump is located above the water surface, which is convenient for maintenance.
