Today we bring you information about hydraulic pumps, specifically basic knowledge centrifugal pumps, their definition, use, operation and types.

What is a Centrifugal Pump?

Centrifugal pumps are a type of hydraulic pump, rotating machines that transform the mechanical energy of an impeller into the kinetic energy of a fluid. In this sense, centrifugal pumps increase the speed of fluids so that they can move over greater distances.

Use of a Centrifugal Pump

Within the basic knowledge centrifugal pumps, it is important to know the area in which they can be used; Although its use is very widespread, these pumps are widely used for the transport of liquids containing solid particles in suspension. However, these machines are not very efficient when working with very viscous liquids.

These are the most applied in various industries, including:

  • Food industry: Flavors, oils, fats, tomato paste, creams, chopped vegetables, jams, mayonnaise, chocolate, yeast and others.
  • Cosmetics industry: Creams and lotions, dyes and alcohols, oils, among others.
  • Pharmaceutical industry: Pastes, syrups, extracts, emulsions. Drinks: milk, beer, spirits, fruit concentrates, juices and more.

Other chemicals: Solvents, fuels and lubricants, soaps, detergents, paints, liquefied gases, etc.

Operation

The operation of the centrifugal pumps is based on a rotor, impeller or impeller. This is the element that transfers the energy received by an electric motor to the fluid.

Its operation is very simple: the liquid enters the center impeller or impeller, which has some blades to direct the fluid, and by effect of the centrifugal force, the liquid or fluid is pushed outwards, where it is collected by the housing or body of the pump. Due to the shape of the body, the liquid is led to the outlet pipes or to the next impeller.

Types of Centrifugal Pumps

In the field of basic knowledge centrifugal pumps, there are different classifications according to different parameters:

The flow direction

According to the direction in which the fluid passes through the pump, these can be:

  • Axial: In this case the flow circulates parallel to the axis of rotation. They are very efficient pumps when it comes to raising large flows at low altitude.
  • Radial: In this case, the flow evolves perpendicular to the axis of rotation. They are pumps of high efficiency when the fluid is corrosive or has solid particles. It is also widely used in food industries because they do not contaminate the products.
  • Mixed: It combines the axial pumps with the radial pumps.

Position of the axis of rotation

  • Horizontal: The axis of rotation is horizontal.
  • Vertical: The axis of rotation is in vertical position.
  • Inclined: The axis of rotation is inclined.

By design of the breastplate

  • Scroll
  • Turbines

Suction form

  • Simple
  • Double
