With the development of agricultural science and technology and the adjustment of structure, farmers make full use of low mountain gentle slopes and barren beach resources to develop agriculture on a large scale, but these plots are often difficult to irrigate. Need to buy a pump to raise water for irrigation. So, how to choose the right agricultural water pump? The following agricultural water pump selection manual for farmers' reference.

First of all, it is necessary to purchase pumps according to local conditions. There are three types of commonly used agricultural water pumps, namely centrifugal pumps, self-priming pumps and submersible pumps. The centrifugal pump has a high head, but the water output is not large, and it is suitable for mountainous areas and well irrigation areas. The self-priming pump has a large water output, but the head is not too high, and it is suitable for use in plain areas; the water output and head of the submersible pump are between the centrifugal pumps and the axial pump, it is suitable for use in plains and hills. Users should purchase according to local conditions, water source and water lifting height. Secondly, it is necessary to properly select the pump. After determining the type of pump, it is necessary to consider its economic performance, paying particular attention to the choice of the head and flow of the pump and its supporting power. It must be noted that the head (total head) indicated on the pump plate is different from the head of the water (actual head) when used, because there is a certain resistance loss when the water flows through the water pipe and the pipeline. Therefore, the actual head is generally 10%-20% lower than the total head, and the amount of water is also reduced accordingly. Therefore, in actual use, it can only be estimated from 80% to 90% of the head and flow rate of the signage. The choice of pump power can be selected according to the power indicated on the label. In order to make the pump start quickly and safely used,the power can also be slightly larger than the power required by the pump, generally about 10% higher; if there is power, when purchasing the pump, you can purchase the matching pump according to the power of the power machine.

Finally, it is necessary to purchase water pumps strictly. When purchasing the pump, it is necessary to check whether it is standard (certificate, manual, warranty card.)
