[size=18pt]Select the pump
The first step in designing and selecting an electric motor and electric pump is the ability to calculate the longitudinal drop, local drop, and losses along the pumping path. To calculate the drop in pipes and ducts, there are relationships that are mentioned in the types of pumps. For information on online purchase and price of home water pump, refer to Kala Sanati website.

Also, to choose a home water pump according to the number of floors and the area of ​​the apartment, using the table provided in different products, you can select the appropriate pump to some extent.

Specifications and important parameters for pump selection
Regardless of the different types of pumps used to pump liquids and gases, the main parameters to determine their performance are:

[li][b]Output capacity
Power consumption

[size=14pt]Pump output capacity (discharge)
Pump capacity means the volume of fluid pumped by a pump in a given unit of time. This characteristic is indicated by the letter Q and its unit of measurement is cubic meters per hour (m3 / h), liters per second (l / s) and so on. The value of the pump flow means the actual volume of fluid displaced by the pump ignoring the volume of fluid returned. Theoretical and real value is expressed by the amount of volumetric efficiency. But in modern pumps, thanks to the very good sealing of pipelines and fittings, the actual capacity is equal to the theoretical capacity of the Khat pump.

This characteristic means the energy transferred by the pump to the material and fluid, which depends on the mass unit of the pumped fluid. This unit is denoted by the letter H and its dimensions are in meters. It should be noted that the head is not a geometric characteristic and also not the height at which the pump can raise the pumped medium.

This characteristic means the power consumption of the pump during the fluid pumping operation. The power consumption is different from the amount of useful power consumption of the pump, which is used to transfer energy directly to the fluid. Part of the power consumption that is wasted in the pump due to leakage, bearing friction, etc. The calculation of these characteristics may be different for different types of pumps, which is associated with differences in their design and operating principles


A good pump must work in every situation. ;)
