There are two different types of rotary pumps; one is known as the positive displacement pump, and the other is a centrifugal pump. In order to achieve the best results, it is important to fully understand the difference between the two.
Centrifugal pumps usually have various levels of flow, depending on the pressure of the liquid being pumped. A positive displacement pump has a constant flow, which is not affected by pressure at all. The main advantage of the centrifugal pump is that it works best when pumping water, making it the pump of choice for the fire service. The positive displacement pump is better with thicker liquids, such as slurry. Because of this, it is popularly ...

There are two different types of rotary pumps; one is known as the positive displacement pump, and the other is a centrifugal pump. In order to achieve the best results, it is important to fully understand the difference between the two.
Centrifugal pumps usually have various levels of flow, depending on the pressure of the liquid being pumped. A positive displacement pump has a constant flow, which is not affected by pressure at all. The main advantage of the centrifugal pump is that it works best when pumping water, making it the pump of choice for the fire service. The positive displacement pump is better with thicker liquids, such as slurry. Because of this, it is popularly used for sewer maintenance, as well as in chemical plants.
There are disadvantages to these two types of pumps. The centrifugal pump requires experienced hands when pumping at full pressure because, as the water pressure increases, it takes greater strength to control it. The positive displacement pump does not have this problem, but it does struggle to maintain an even flow with high-viscosity liquids.
Rotary pumps are used in a variety of different businesses, including professional landscaping firms, drain specialists and pipeline services. The pumps are usually housed in special pumping stations.
