Types of Centrifugal Pumps
Centrifugal pumps use rotating impellers to increase fluid pressure and move the pressure through a central piping system. They have a built-in mechanical seal that usually adds a necessary buffer to protect the pump shaft.
Basically, centrifugal pumps are used in manufacturing and other industries that transport liquids from one point to the other. It uses centrifugal force to move the liquid through a plumbing system and hoses. Liquid then flows around the pump casing and deposits in the narrowing areas of the pipe with the goal of building pressure on it.
Centrifugal pumps also come in different types depending on their uses. Enlisted below are commonly used centrifugal pumps:
Single-Stage Radial Flow
This is the most common type of centrifugal pump. It has a water pumps impeller that brings liquid into the impeller’s centre and pushes it through the impeller vanes. As it goes through the shaft, the water goes down the narrow vanes, increasing the pressure in the pump to generate a strong flow.
Multistage Centrifugal
This contains more than one impeller mounted on a common shaft or using different shafts. It produces overall pressure and discharges higher quantities of liquid. In this case, water flows inward to different impellers, speeding the flow of water into the vanes and generates higher pressure than a single-stage pump can do.
Magnetic Drive
These are the most expensive types of centrifugal pumps. This type of pumps use magnetic field that joins a drive motor and impeller to pump fluids and increases pressure. They have similar designs to the single stage, but, because of the presence of the magnetic field this will no longer need a long shaft or seals between the motor and impeller. Leaks can be virtually eliminated and it allows significant reductions in internal contamination, wear and friction loss.
Mechanically Coupled
Is a centrifugal pump with a rotating impeller driven by the shaft with a motor connected by a strong seal. These are inexpensive centrifugal pumps available for use and offers moderate pressure and flow rates than other types, though these are more prone to leaks.
