Main types of centrifugal pumps

Centrifugal pump is kinetic energy pump, due to the role of centrifugal force, so that the liquid first increase kinetic energy, and then converted into pressure energy. Centrifugal pumps can be used in a wide range of industrial applications, offering high operational efficiency in terms of versatility and performance. The main types of centrifugal pumps include two configurations:

• Horizontal centrifugal pump

• Vertical centrifugal pump

What is a horizontal centrifugal pump?

Horizontal centrifugal pumps are one of the most widely used pump models in industrial applications. The design configuration includes aligning the pump head with the pump motor on the same plane. The positioning of the motor and pump head can be tightly coupled (without coupling) or long-coupled (with coupling). The main application areas include spraying systems (for example, in the automotive or paint industry) and water purification systems for circulating very dirty liquids with suspended solids.

Horizontal centrifugal pump application advantages

Horizontal centrifugal pumps are easier to install and maintain because they are designed to be more accessible to the operator. Horizontal pumps can be easily adapted to different suction requirements and are particularly suitable for placement in space-constrained plants.

What is a vertical centrifugal pump?

This type of pump has a vertical arrangement where the motor is located above the pump shaft. Also in this case, the coupling between the motor and the pump head can be very close or very long, where the gasket bracket is used as the support of the motor. The most common applications involve fluid delivery systems, even solid parts in suspension, lifting stations, or stationary devices where the pump is directly immersed in the tank.

Application advantages of vertical centrifugal pump

Vertical centrifugal pumps are designed to lift fluids from high depth areas. Vertical pumps take up less space than horizontal models, making them an excellent solution for installations where available floor space is limited. Even at high temperatures, vertical pumps are ideal for pumping high-pressure fluids. Vertical pumps use electric motors, which may limit their use in some cases.
