Differences Between Horizontal and Vertical Slurry Pumps



Slurry pump is widely used in various industrial fields such as construction and so on. And there are two different types of slurry pumps, and they are horizontal slurry pump and vertical slurry pump. Today, as a slurry pump supplier, I’d like to introduce the differences between them.

Horizontal Slurry Pump

When the position of the pump shaft is parallel to the horizontal plane, it is called Horizontal Slurry Pump. The horizontal slurry pump is a single-stage single-suction axial suction cantilever horizontal centrifugal pump with high-strength and wear-resistant materials for the over-flow parts. according to the different suction media, the filter components of various materials can be exchanged.
Horizontal slurry pump is suitable for conveying strong abrasion, high concentration, corrosive large or fine particle slurry, this series of slurry pump can be widely used in metallurgy, mining, electric power, coal mine and other industries to transport abrasive slurry containing a large number of solid materials.

Vertical Slurry Pump

When the position of the pump shaft is perpendicular to the horizontal plane, it is called a 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.
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.

The Main Differences

Structural Characteristics

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

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.

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.


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.

Situations Need to Use the Vertical Slurry

1. The floor space of the pump is restricted.
2. Suction deeper groundwater. For liquids such as petroleum or brine, vertical deep-well pumps are required. Another reason why large single-suction pumps are vertical is that water-lubricated bearings with a simple structure can be used. At this time, the water-lubricated bearings have a small load and light wear increases the bearing life.
3. In places where the water level fluctuates greatly, the pump should be installed at a low water level. In this case, the vertical type is used to reduce the area of the station and reduce earthwork. Reduce infrastructure investment. Large single-suction centrifugal pumps and axial flow pumps are mostly vertical.
4. Some high-pressure and small-flow pumps are prone to unstable operation due to the large number of stages and the slender shaft of the pump. One of the measures to change this situation is to use a vertical pump and subject the pump bearing to a certain tension.
