Firefight centrifugal pump

A fire centrifugal pump is a special type of pump designed for use in fire systems. Its main function is to provide high pressure and flow of water or other extinguishing medium to fight fire. These pumps are capable of transporting large quantities of water over long distances. The principle of operation of centrifugal pumps generally consists in the use of centrifugal force that acts on the transported liquid. It is important that these pumps are able to work under extreme conditions and be reliable even in an emergency. Therefore, they are designed to withstand high temperatures and to be resistant to the corrosive effects of fire-fighting media.
