How to calculate the flow rate and head of a slurry pump?

How to calculate the flow rate and head of a slurry pump? When selecting a slurry pump, we first need to determine the desired flow rate and head. We need to choose the model of the slurry pump and the appropriate motor size based on the required flow rate and head at the site. So what are flow rate and head? Let Pan Shi Pump Industry explain these two terms in simple language.

According to the design principle of a slurry pump, it belongs to the category of centrifugal pumps, so we can refer to the concept and calculations of head in centrifugal pumps for understanding.

The head of a slurry pump, also known as pump head, refers to the height at which the pump can lift and transport the slurry, as well as the force applied to the slurry. It can also be understood as the energy obtained by the pump per unit weight of the slurry. The head of the pump depends on the size of the impeller, the curvature of the blades, and the rotational speed.

The flow rate of a slurry pump refers to the amount of slurry that needs to be processed by the pump in a unit of time. For example, if we need the pump to handle 20 cubic meters of slurry in one hour, then the flow rate is 20 cubic meters per hour.
