self priming pump

A self-priming pump is a type of centrifugal pump that can automatically evacuate the air from the suction pipe and begin pumping liquid without external assistance. This type of pump is commonly used in applications that require periodic or intermittent pumping or where the pumping conditions can change frequently.

Description

A self-priming pump is a type of centrifugal pump that can automatically evacuate the air from the suction pipe and begin pumping liquid without external assistance. This type of pump is commonly used in applications that require periodic or intermittent pumping or where the pumping conditions can change frequently.

A self-priming pump has a unique design that allows it to create a vacuum in the suction pipe, which pulls the liquid into the pump. This is achieved by using an impeller that creates a partial vacuum, which draws the liquid up into the pump housing. Once the air is evacuated from the suction pipe, the pump is able to continuously pump liquid.

One of the benefits of a self-priming pump is that it can operate in areas where the fluid level is variable or where the pump is frequently turned on and off. This saves time and improves the efficiency of the pumping system. These pumps are also designed to handle fluids with a range of viscosities, making them suitable for a wide range of applications.

Self-priming pumps are commonly used in the water treatment, petrochemical, agriculture, and construction industries, where they are used for irrigation, slurry transfer, and dewatering. They are also commonly used in applications that require handling of viscous fluids, such as food processing.

In summary, a self-priming pump is a centrifugal pump that has the ability to evacuate air from the suction pipe and begin pumping liquid without external assistance. They are useful in applications where fluid levels are variable or where frequent on/off cycling is required. Self-priming pumps are suitable for a variety of industries and are designed to handle fluids with varying viscosities.
