What Is A Vortex Pump?

Vortex pump is a kind of high head pump with simple structure, usually composed of impeller, pump body, pump cover and so on. The impeller is a disk with many small blades on its outer edge, and the liquid repeatedly swirls in the blade and the flow channel of the pump body.

The efficiency of the vortex pump is low, usually between 15% and 40%, but its head is high, and the change between the head and the flow is small, so it has certain advantages in some specific occasions, such as the need to pump the liquid with high head. In addition, the flow rate of the vortex pump is small, which is suitable for small flow situations. Due to the low efficiency of the vortex pump, its operating efficiency needs to be considered in the design to ensure that it can meet the actual needs.

Marine vortex pump is mainly used in Marine systems need to transport high viscosity, high head or large flow of liquid occasions, such as ship bilge pump, ballast pump, fuel pump, oil pump and so on. Vortex pump has the characteristics of simple structure, high head, small flow and no pulsation, so it has a certain application in the Marine industry.

For example, in oil tankers, vortex pumps can be used to transport liquids such as fuel oil and lubricants; In chemical tankers, vortex pumps can be used to transport a variety of corrosive liquids. In addition, in some special purpose ships, such as scientific research ships, ocean engineering ships, etc., also need to use vortex pumps to meet special needs.

It should be noted that the efficiency of the vortex pump is low, usually between 15% and 40%, so its operating efficiency needs to be considered in the design to ensure that it can meet the actual needs. At the same time, because the flow rate of the vortex pump is small, it is necessary to use multiple vortex pumps in parallel for conveying when large flow is required.
