What Is a Nameplate?
Every pump and water pump has a nameplate regardless of its brand and type. The nameplate displays the identity of pump. Therefore, a nameplate guarantees the authenticity and the manufacturing brand. A pump with no inauthentic and fake. nameplate is probably
●hashtag#Type: it shows the type and the product model. Mostly, manufacturers give each model a unique name and number.
●hashtag#Flow_rate (Q): Volumetric flow rate (discharge) is mentioned on the nameplate with the symbol Q or is simply referred to as Flow Rate. The related measuring unit is placed in the parenthesis.
●hashtag#Head (H): H stands for the head of the pump, the maximum height which the pump can lift liquid, and is expressed in m³/hour, liters/minute or gallons/minute (GPM).
●hashtag#Minimum_head (Hmin): The other part is for the minimum height up to which the liquid is pumped.
●hashtag#Maximum_head: Then we have Hmax, which means the maximum height up to which the pump can lift the fluid. We have to remember that the flow rate is zero at this point, and there is no flow rate further up.
●hashtag#Power: One of the most important factors for a pump is power, the amount of energy the pump consumes per unit of time, which is expressed in horsepower (HP) or kilowatt (kW). P2 is the starting power of the device known as the nominal power of the motor, and P shows the main and constant power the pump requires.
●hashtag#η and hashtag#MEI: Then, we have some parts under the names of efficiency (η) and minimum efficiency index (MEI). Eta (η) defines the power in percent. The larger the number is, the more the efficiency. MEI represents the international standard according to which the product is designed. Remember that these items may not be mentioned on some nameplates.
●hashtag#Voltage: In this part, we see V stands for the product voltage, and the front number defines whether it is single- or three-phase. For example, V3~ 230 means the product voltage is 230V in three-phase mode.
●hashtag#Capacitance: Item C stands for the capacitance of the capacitor, expressed in microfarad. This item may not be mentioned in some nameplates.
●hashtag#Cl: The symbol Cl stands for pump insulation class. The insulation class is the level of protection in electric products.
●hashtag#IP: The next part illustrates the protection degree (IP). It means that the pump is splash proof and the electric and movable parts are designed in such a way that pump is not damaged if exposed to foreign objects larger than 1mm in diameter.
●hashtag#A: This item shows the current intensity and is expressed in amperes.
●hashtag#Frequency: The frequency, which shows the number of current oscillations, is expressed in hertz (Hz).
●hashtag#rpm: The term rpm stands for the phrase revolution per minute which shows the speed of electric motor.
●hashtag#Temperature (T): This part shows the maximum allowed temperature of the liquid moving through the pump. The temperature is expressed in degrees centigrade or Celsius (°C).
●hashtag#Overload_Protector: The next is for the thermal overload protection. The word YES means that the product is equipped with thermal protection. If the motor inner temperature rises above a certain limit (maximum allowed temp.)
●hashtag#Continuous_duty: Then, we have the word continuous duty meaning that this pump is suitable for permanent functioning and can work uninterruptable.
●hashtag#Flow_rate (Q): Volumetric flow rate (discharge) is mentioned on the nameplate with the symbol Q or is simply referred to as Flow Rate. The related measuring unit is placed in the parenthesis.
●hashtag#Head (H): H stands for the head of the pump, the maximum height which the pump can lift liquid, and is expressed in m³/hour, liters/minute or gallons/minute (GPM).
