Crown Self-Priming Centrifugal Pumps: How it Works, Types, Features, and Benefits

When pumps have to be used for several intermittent operations in processing plants, you would ideally want something that can offer increased efficiency. This is exactly what self-priming pumps offer.  Self-priming pumps always have some amount of start-up liquid in their body or cavity, so they are always ready to start the pumping process. Crown Centrifugal Pumps with Self-Priming capabilities are the best in the market when it comes to efficient handling of intermittent operations. 

Manufactured by Crane Engineering, Crown Centrifugal Pumps are Self-Priming Centrifugal Pumps that are designed for heavy-duty dewatering and construction wastewater applications. They basically come in two different configurations –

·         Close-Coupled and Frame-Mounted

·         V-Belt Drive

The Crown Self-Priming Pumps offer superior performance up to a maximum of 4,400 GPM and the pump fluids up to a height of 184 ft (or 56m). Besides this, they can also handle spherical solids measuring 80 mm.

How do Self-Priming Centrifugal Pumps work?

Centrifugal pumps are usually not designed to be self-priming. The pumping action in centrifugal pumps occurs when the impeller rotates to displace the liquid in the cavity so that it is forced to flow out. In the standard centrifugal pumps, the fluid enters the impeller and is then discharged to the outer perimeter. However, air pockets can form, which can impair the proper functioning of the pump. Self-priming centrifugal pumps overcome this issue by mixing any residual air with the fluid through a priming process. Through this process of blending, the resulting mix is able to move through the pump’s body rapidly on start-up, and the normal pump operations start with ease.
