Odstredivé čerpadlo

What are centrifugal pumps?

Odstredivé čerpadlá na vodu are devices that use rotational energy to move liquids by applying centrifugal force. The centrifugal pump works by spinning an impeller driven by an electric motor, which creates a flow of liquid by pushing it to the pump’s periphery. The fluid gains both speed and pressure as it passes through the impeller. They are suitable for pumping not only clean but also slightly contaminated water without sand or gravel.

Applications of centrifugal water pumps

This pump is very energy-efficient, as it uses little electricity to move a significant amount of water. Most models are designed for low-viscosity liquids with minimal or no solid particles. Odstredivé čerpadlá na vodu are one of the most common types of elektrické čerpadlá na vodu, widely used across various industries and households to pump water, chemicals, and other liquids. These vodné čerpadlá are characterized by their use in activities that require moving large volumes of water with low pressure. Odstredivé čerpadlá na vodu do not achieve high water head height and are mainly used to deliver water to low-height areas. Odstredivé čerpadlá na vodu are preferred by many farmers and property owners in suburban areas. Their practical application enables garden irrigation and household water supply. They are often used to create drip irrigation systems, saving much effort in watering agricultural lands.

!!! The pump’s impeller must always be submerged in water when starting, as it cannot draw liquid otherwise. It is highly recommended to use a check valve to prevent backflow of liquid from the pump into the reservoir.

!!! If transporting drinking water, ensure that all components and the hose are certified as safe for contact with food and beverages. 

!!! Always consider the pump curve, which shows the relationship between head height and flow rate. The higher the head height, the lower the flow rate, and vice versa.

How to choose the right centrifugal pumps

When selecting an odstredivé čerpadlo, consider the following factors:

• Pressure and Flow Rate: Determine the required pressure and flow rate for your application.

• Water Head;

• Inlet and Outlet Size – measured in inches; 

• Suction Height – measured in meters;

• Power;

• Voltage – measured in volts.

• Type of Liquid: Consider the chemical composition of the liquid you will be pumping.

• Energy Efficiency: Choose a pump that offers high efficiency and low operating costs.

• Brand and Quality: Opt for established brands like Metabo, Raider Garden Tools, and Raider Pro.
