Mud agitator

A Mud Agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.^[1]

Types of Agitator Mounting

• Horizontally mounted agitator
• Vertically mounted agitator^[2]

Types of agitating shaft seal

• Mechanical seal
• Packing seal^[3]

Types of Agitator Impellers

Types of Agitator Impellers

• Radial Flow Impeller. Figure 1 shows a radial flow created by the impellers wherein the circulation is predominantly horizontal.
• Axial Flow Impellers. Figure 2 shows an axial flow created by the impellers wherein the circulation is predominantly axial fluid movement.

Types of Impeller Blades

• Flat blade impeller
• Canted blade impeller
• Contour blade impeller
