Surface pump for a well: what is it, basic parameters for selection

Best Conventional Surface Pumps

Conventional surface pumps are installed outside the source, connecting the device to it using a conventional hose. In case of year-round use of the pump, it is necessary to provide protection for the housing from low temperatures, since water frozen inside the working cavity can lead to breakdown. Typically, the power of a household surface pump is designed to pump water from a depth of up to 10 meters. The advantages of such devices are simple installation, primitive design and high mobility.

The best pumping stations

VORTEX ASV-1200/24N

It is a domestically produced model that can be used to supply drinking or industrial water to a summer cottage or in a private house.

1. GILEX Jumbo 50/28 Ch-14

Another domestically produced model, and, according to user reviews, this design is the best surface pump designed for creating an autonomous water supply system. The volume of the expansion tank is 18 liters - quite enough for domestic needs. It is quite enough so that the pump does not turn on after two or three liters of water have been consumed from the system. If necessary, the operation of the device can be adjusted by creating higher pressure in the pipes or, conversely, lowering it. Capable of lifting water from a depth of more than 6 meters. Even if the suction pipe is located at the bottom of a well or borehole, no sand or other abrasive particles will be drawn in, since the power of the device is only 500 W, although experienced users recommend installing a coarse filter at the inlet to protect the motor blades from mechanical damage.

According to the manufacturer, this model is able to function normally even when using dirty water or water containing a large amount of dissolved gases or salts. Thorough protection against leaks is provided by seals made of graphite-ceramic materials. Experienced plumbers specifically note the short-circuited system on which the electric motor operates. This allows you not only to save on electricity, but also to extend the service life of the equipment.

Advantages:

• It starts smoothly and there are no water hammers in the water supply system;
• Reasonable cost;
• There is also reliable idle protection;
• The unit has high-quality protection against voltage surges;
• Low energy consumption.

Flaws:

• Not detected.

The best circulation pumps for heating

Heating circulation pumps are used to force water circulation in a circle. The devices can also work with hot water, since their main area of ​​application is heating systems. The devices create pressure differences that help the fluid overcome the resistance created in the pipe. When choosing a circulation pump, you should pay attention to the pressure created, which determines how large systems the device can serve, productivity and the maximum water temperature with which the device can operate.

The leader in terms of sales of surface circulation pumps is . Grundfos

is a Danish concern, the most popular and reputable company for the production of pumping units. The production volume is more than 16 million products per year. The company's head office is located in Denmark, and its main production facilities are located in Germany. Therefore, Grundfos pumps are often called German, as evidenced by the high build quality. In 2005, a plant for the production of Grundfos pumps was opened in Russia (Moscow region).
