Characteristics of surface pumps

Surface pumps are intended for the construction of wells and wells. They supply water in large volumes for use in everyday life and on an industrial scale. Correctly selected surface pump on mir bureniya indispensable for watering and irrigating gardens, filling large tanks or pools, draining ponds.

Features

The devices are activated when lifting with the subsequent pumping of water located at a height of up to 25 m. If the well shows a greater depth, it is better to use a submersible pump. Technical properties:

1. location only above the liquid level;
2. the presence of a motor of 0,6 kW, which has moisture and thermal protection;
3. the pumped liquid shows no more than +65 degrees;
4. form – vertically or horizontally elongated type;
5. closed construction with a weighted body, it is made of stainless steel or cast iron.

Recommendations

It is not necessary to purchase a pump in advance, it should be selected taking into account the already prepared water source. Surface pumps are divided into separate types.

If we are talking about vortex models, they are used in places where clean water is pumped, which enters directly into the premises. Its direction is tangential to the shaft. A distinctive feature is the creation of a large pressure and in compact sizes, the supply of a large volume of liquid.

Centrifugal units differ in that the water is set in motion due to the rotation of shafts and wheels inside the entire structure. If self-priming devices are considered, to start their operation, the body is first filled with liquid. Centrifugal pumps with an external ejector are also distinguished. They connect to this element, due to which the depth increases up to 2 times, but the productivity decreases. As for multi-stage structures, they are similar to centrifugal ones, but have several wheels that distill water.

Advantages

The main criterion for choosing a surface pump is the end point of the depth. Among the main advantages, the following are highlighted:

1. creation of a large pressure;
2. simple installation and operation;
3. compact size;
4. affordable cost;
5. rare service with repairs.

Among the nuances, there is an increased noise in the switched-on state, the possibility of pumping only purified water that does not contain impurities. The described equipment does not have protection against negative dry running.
