The centrifugal pump is widely used in industries, especially in the chemical industry for the manufacture of creams, in cosmetics and in the pharmaceutical industry.
It is important to know how do work in order to use them correctly and avoid accidents in the field.
In this article you will learn what centrifugal pumps are, the types that exist and the applications where they are commonly used.
It’s a device designed to move the fluid by means of a rotational energy transfer from a single driven rotor or more, known as impellers.
Although they have different structures, their characteristics and operating principle are always the same.
The following diagram shows its main parts:
The parts that make up this pump are:
Its operation is simple. The fluid enters through the center of the impeller or impeller of the machine, which has a curved blade called a vane and serves to direct the fluid.
Then, because the pump produces centrifugal force, the fluid is propelled to the outside, where it is collected by the pump body or casing.
Thanks to its structure, the fluid is conducted through the outlet pipes.
The types of pumps are:
The centrifugal pumps for water conveys fluids using rotational energy that is driven by a motor.
Its fluid is accelerated by the impeller, a series of triangular or curved plates that are kept submerged in the fluid, depending on the type of fluid, the impeller can be open, closed or semi-open.
This type uses a mixture of water and air in order to achieve a primed pumping condition. Applications where it can be seen are in flood control, sewage and construction dewatering.
Consists of more than one impeller and they are distributed in series on the same shaft.
The advantage of these multi stage centrifugal pumps is that they have better efficiency due to their narrower impeller clearances and smaller diameters.
They are pumps that have a vertical shaft that include rotating impellers and stationary bowl stages in order to process guide vanes. They are used when the water pumping level is below the pump limits.
It transforms the mechanical energy of a runner or impeller into pressure or kinetic energy and, by means of centrifugal forces, expels the cryogenic liquids to the outside.
This type is one of the most common and is used with most systems. Pressure is developed primarily by the action of centrifugal force, allowing water to enter the suction inlet and pass through the center of the impeller.
It has its suction at the bottom of the pump casing and its discharge at the top.
It is a type of pump that is very frequently used to pump liquids in various commercial and industrial applications.
They are similar to self-priming pumps and have a pumping speed of up to 7 mWS depending on the size.
When the direction of rotation changes, it can also be used to backwash the diaphragm.
Its shaft is placed horizontally, usually between the cantilever or bearings, and is used by industries that transfer large quantities of fluids.
This pump has the ability to handle fluids with solid matter. It is used to move a mixture of solids and liquids in various industries with a broad spectrum of applications, such as drilling mud pumping, mine dewatering and sedimentation pond dredging.
They are suitable for liquids that have a lot of corrosion and are without solids in suspension. Their movement is made by means of magnetic seals and they are designed for the environmental and chemical sectors.
They are used for the extraction of water in boreholes or deep wells and their operation is based on transforming mechanical energy into kinetic energy, allowing the movement of the liquid through the pipe.
The radial has a fluid exiting the impeller after rotating 90° in relation to the suction and the axial flow moves parallel to the shaft. The mixed is a mixture of radial and axial properties, but with a higher flow rate.
It has a single volute casing, where the flow is discharged from the impeller and enters the volute by wrapping around the impeller.
They are a type of hydraulic pump that works to convert the mechanical energy of an impeller or impeller into pressure or kinetic energy of a complicated fluid.
Used when the liquid head is below the pump head and in various industries in the pharmaceutical, chemical, food or cosmetic sector.
Manufactured to pump fluids such as beverages, beer, water, milk and various products in the pharmaceutical, food and chemical sectors.
Both the suction and discharge inlets are on the same axis as the fluid conduction pipe.
They are manufactured for the impulsion of clean liquids that are non-abrasive, widely used in industrial and civil applications.
These are all the most common types of pumps used in various industries.
The advantages they have are:
Disadvantages include:
The centrifugal pump vs. positive displacement pump are very powerful tools with the ability to move fluids through municipal and industrial systems.
The normal pump draws a flow into a cavity and then forces the fluid out of the cavity by suction.
While the centrifuge has a rotating impeller that draws the fluid into the pump and expels it from the outlet at a higher velocity.
Applications include:
Has a wide utility, where it is an essential part for all industries, so it is very likely that you will need one.
