If you are looking for an electric pump for autoclave or a motor pump to irrigate the vegetable garden and garden , or even pumps for drainage or spraying , swimming pools and emergency , you are in the right place!
Use the filter system for the advanced search of the electric pump or motor pump with internal combustion engine that best suits you. If you still do not know how to choose the pump or motor pump suitable for the use you need to make of it, continue reading to clarify any doubts.
When you are looking for an electric pump or a motor pump , whether it is to be used for the domestic water supply in homes, to irrigate vegetable patches and gardens or to spray in agriculture, the first questions to ask are how much water I need. ? how much power do i need?
Answering these questions is not easy, the variables to be considered in water systems are many and vary from case to case. For example, in a house or building where there will be 3 kitchens and 6 bathrooms, I will obviously need a greater range than in a house with 1 kitchen and 1 bathroom.
In order to accurately determine the most suitable pump or motor pump , in addition to the type of power supply whether electric or petrol, the main specifications to be identified are the flow rate and the head of the pump .
The flow rate indicates the volume of water that is moved in a given period of time. This value is usually expressed in Liters per Minute (l / min) or in Cubic Meters Hour (m³ / h) .
1 m³ / h = 16.67 l / min
To correctly establish the flow rate necessary for our water system, it is necessary to know the number of taps that can be opened at the same time and to add their flow rate to obtain the total flow rate required.
For traditional domestic systems, the following values can be taken into consideration:
For garden sprinklers, on the other hand, reference is made to the area of the surface to be irrigated:
To give an example, assuming you need to identify the water flow rate required for a house with 1 kitchen and 2 bathrooms with 200m² of garden:
1 KITCHEN + 2 BATHROOMS + 200 m² = 2 m³ / h + 1.5 m³ / h = 3.5 m³ / h = 50 liters / min
Now that we know what capacity our system needs, we can move on to the second fundamental data to choose the most suitable pump.
The head is the difference in level (indicated in meters) between the level of the water sucked by the pump and the level of the pumped water.
The drawing clearly explains what is meant by prevalence:
Now that we have clarified the meaning of flow rate and head, we can read the technical data sheet of the pump where we will find the performance curves that indicate the real performance of the pump. Let's see an example:
To use a pump at its best, it is strongly recommended to keep the relationship between head and flow rate in the center of the diagram.
Centrifugal pumps are the most common in the most diverse sectors, in a vast field of industrial and civil applications due to their characteristics, including:
However, centrifugal pumps are not suitable for transporting very viscous liquids, and it is precisely in these cases that the positive displacement pumps come into play.
There are different types of volumetric pumps, each with different properties, for example some pumps guarantee higher pressures for the same power, others instead higher flow rates. There are types of pumps more suitable for treating solid bodies of considerable size, others more suitable for aggressive fluids, etc.
