Slurry pump is a large-scale centrifugal pump, which is mainly used to transport media containing abrasive solid particles. It is an indispensable general equipment in mining, chemical, coal and metal smelting industries. In the alumina production process, the slurry pump mainly transports the raw material slurry with high temperature, strong abrasiveness and large solid particle content, so it is also called the slurry pump.
Most of the slurry pumps used in alumina production at home and abroad have experienced faults such as easy wear of overflow parts, short service life, rapid equipment vibration, and rapid decline in operating efficiency. These faults will make it difficult for the slurry pump to complete the task of the rated load. , Which has a great impact on production. These failures of the slurry pump are not only related to the harsh conditions of production, but also have a lot to do with the quality of daily maintenance and overhaul of the equipment. To reduce the failure rate of the slurry pump and improve the efficiency of equipment utilization, it is necessary to use the slurry pump correctly and formulate an appropriate maintenance plan.
Classification of Common Slurry Pumps
According to the classification of the working principle, the slurry pump is a kind of centrifugal pump. The slurry pump relies on the rotation of the impeller in the pump cavity to drive the slurry to generate centrifugal force during operation, so that its energy is increased for delivery.
According to the different conveying media, centrifugal pumps can be divided into clean water pumps, solution pumps and slurry pumps; and according to the different angles of division, there are different types. According to the number of centrifugal pump impellers, they can be divided into single-stage impeller slurry pumps. And multi-stage impeller slurry pump; and according to the relative position of the slurry pump shaft and the horizontal plane, it can be divided into horizontal slurry pump and vertical slurry pump; according to the classification of the pump casing, it can be divided into single suction Slurry pump and double-suction feed slurry pump; and according to the different structure of the pump casing, it can be divided into horizontal open type and vertical combined type. Among these types, the single-stage horizontal single-suction slurry pump is the most widely used in alumina production.
The Main Factors to Be Considered in The Selection of Slurry Pump

Due to the balance of many factors such as flow, pressure, viscosity, abrasiveness, particle size and particle type, choosing the right slurry pump for your slurry application can be a complex task. Application engineers who know how to take all these factors into consideration can be of great help.
When determining which slurry pump is best for your specific application, follow these four simple steps.
Determine the nature of the material being pumped by the slurry pump
Consider the particle size, shape and hardness (the possibility of affecting the wear and corrosion of pump components)
The corrosiveness of the slurry.
