Temperature is the physical quantity that indicates the degree of heat and cold of an object. Microscopically, it is the severity of thermal motion of an object's molecules. The temperature can only be measured indirectly by some characteristic of the object as a function of temperature, and the scale used to measure the temperature value of the object is called the temperature scale.
It specifies the starting point (zero point) of the temperature reading and the basic unit of the measured temperature. The international unit is the thermodynamic temperature scale (K). At present, other temperature standards used in the world include Fahrenheit temperature scale (°F), Celsius temperature scale (°C) and international practical temperature scale.
For centrifugal pumps, the liquid temperature is one of the most important specifications.
Clean water pumps: less than 80℃
Hot water pumps: More than 100℃
High temperature pumps: More than 200℃
