Slurry is pumped using a special pump called a slurry pump, with an impeller powered by a motor and a seal to keep the slurry from leaking. The motor is turned on to make the impeller spin, creating a suction to pull the slurry into the pump, and then it is pushed out into pipes and moves to where it needs to go.
Slurry pumps are special types of pumps that are designed to handle highly viscous or abrasive liquid and solid materials. Slurry pumps are used in many industries for transferring liquids with suspended solids, such as wastewater treatment, chemical, mining, and oil and gas production. In this blog post, we will discuss how slurry pumps work, the different types and features of slurry pumps, the selection criteria, and their applications and benefits. We will also look at some common troubleshooting tips and safety precautions to consider when using a slurry pump.
Types of Slurry Pumps
To understand how slurry is pumped, let’s explore the two main types of slurry pumps: centrifugal slurry pumps and positive displacement slurry pumps.
Centrifugal Slurry Pumps
Centrifugal slurry pumps are an important piece of equipment used in many industrial processes. They are designed to move a mixture of fluid and suspended solids, such as sand, mud, or slurry, through a piping system. Centrifugal slurry pumps contain a rotating impeller which is used to increase the pressure of the slurry as it is passed through the pump.
This increased pressure forces the slurry through the piping system. The centrifugal action of the impeller also helps to reduce the size of the solids in the mixture, allowing for a smoother flow. Centrifugal slurry pumps are reliable and efficient, making them a popular choice for many applications.
Positive Displacement Slurry Pumps
Positive displacement slurry pumps are mechanical pumps used to move abrasive and viscous materials such as slurries, sludges, and pastes. They are able to handle high-pressure applications, and are designed to generate pressure and flow in order to push the slurry through the system.
These pumps use a rotating impeller to draw in the slurry and then increase the pressure of the liquid to move it through the system. The impeller rotates inside a casing, which creates a chamber of liquid inside the pump. As the impeller rotates, it draws in the slurry and forces it through the discharge port.
Positive displacement slurry pumps can be used to move a variety of materials, including mud, sewage, and other abrasive slurries. They are commonly found in industrial and mining operations, as well as in wastewater treatment plants.
Due to the nature of slurry, these pumps must be designed to handle high-pressure applications, as well as the abrasive nature of the material. This type of pump is also designed with a large number of ports, which allow for better control of the flow and pressure of the slurry.
