Choosing a country pump for pumping water: which equipment is better to purchase?

Owners of summer cottages often face the problem of pumping dirty water. To clear the well of sand and clay or to remove dirty water from a decorative pond - pumps for pumping water can help with any of these problems. The presence of such aggregates on the farm is especially valuable when the basements are flooded, or the snow melts in the spring. Unlike well and borehole units, pumps for pumping water are able to pass small stones, solid particles and fibers, which is why they are indispensable assistants in the conduct of a summer residence.

Universal surface units

Surface units are designed to work with slightly contaminated water. They are capable of passing solid particles whose size does not exceed 1 cm.

Depending on the method of water intake, all country water pumps are divided into two categories: surface and submersible

The main advantage of such pumps is ease of installation and ease of operation. The indisputable advantage of surface pumps is the ability to move them around the site, cleaning the room in case of bad weather. This is very convenient, because the universal unit can be used for different needs. To start the pump, it is enough to place it on a flat platform, lower the intake end of the suction hose into the water, and then connect the device to the mains. Submersible units themselves shut off when the motor overheats, they also have protection against electric shock and therefore do not require additional maintenance. The suction depth of surface units is limited: most models can operate without overloads at a depth of about five meters.

In the process of working with such an aggregate, only the inlet pipe is immersed at the bottom of the reservoir. The device itself is located not far from the fence, installing it on a flat, solid surface.

Most models of surface water pumps for pumping water do not differ in strong capacities: they are best purchased for infrequent applications. Such a unit will successfully cope with pumping water from the basement and watering the garden, carried out no more than once a week. But with daily use, it quickly fails.

On sale you can find surface units in metal and plastic cases. Metal, although they hum during operation, are not afraid of shock and have a longer service life. Plastic ones are much cheaper and work much quieter, but still not strong enough.

Tip. To reduce the level of "growling" of the pump during pumping out water, you need to put it on a rubberized mat, which will suppress vibration.

Since in the process of pumping water the unit is placed on the street, pumping water at a temperature below zero, there is a risk of freezing of the system. Therefore, in the cold season, the surface pump is best placed indoors or carefully covered.

Powerful submersible pumps

Unlike surface pumps, submersible units have higher power, which greatly expands the scope of their application.

Submersible pumps can be installed not only in man-made wells and wells, but also in open water bodies

Powerful devices are capable of pumping out heavily contaminated water, which contains large solid particles with a diameter of 1 to 5 cm. The devices are equipped with wide working chambers through which contaminated water, together with garbage particles, is freely pumped out without clogging the system itself.

Depending on the performance and power of the device, household and industrial pumps are distinguished. For cottage use, household pumps for pumping water are quite suitable. Such aggregates, grinding sludge and plankton of a reservoir, will provide garden beds with additional natural fertilizer.

Devices for highly polluted water

Wanting to purchase a universal water pump that can successfully cope with domestic wastewater and dirty waters, it is worth giving preference to fecal pumps. Their main purpose is to pump out contaminated water, which contains solid waste and long-fiber inclusions.

Fecal pumps are able to drive into water with the inclusion of particles, the size of which reaches 10 centimeters in diameter

A distinctive feature of these units from submersible systems is the presence of a grinder, which is first able to grind all solid elements into smaller particles and only then send them to the system for further pumping.

In the manufacture of fecal pumps, high-strength materials are used that have increased resistance to aggressive environments, which are not afraid of chemical decomposition reactions. The service life of such units is more than 10 years.

Criteria for choosing a specific model

When choosing a submersible pump, the main thing is not to lose, and therefore you need to take into account a number of key points:

  • Scope of the pump. When choosing a pump, you need to build on what functions it will perform. Planning to use the unit only as necessary for cleaning flooded rooms or watering the garden from a nearby reservoir, it is enough to purchase a pump with a capacity of 120 liters per minute. If you plan to install the pump in a drainage system, it is better to purchase a more powerful unit. The cost of the pump depends primarily on the pressure - the ability to push water to a certain height, and productivity - the amount of pumped liquid in one minute.
  • The location of the suction valve. Units whose suction device is located in the lower part of the housing are capable of quickly and almost completely pumping water out of the basement or tank. But placing such an aggregate at the bottom of a reservoir, one should be prepared for the fact that in the process of pumping along with water it will capture a large amount of silt sediments. Therefore, for these purposes, it is better to choose models with the placement of a suction device in the upper part of the housing, or to install devices on a special stand.
  • Float auto shut off. The presence of a float that responds to changes in water level and gives the command to turn off the engine, greatly facilitates the work with the unit. The automatic system prevents overheating of the motor in the event that after pumping out all the water, the pump will run “dry”. Having spent a little more on a pump equipped with an automation system, the owner does not have to spend time being near a working device, waiting for the completion of the process.

Since the pump for pumping water will mainly work in an aggressive environment, when choosing a model, you should pay attention to the material of manufacture of the housing and the main parts. The greatest resistance to external influences is cast iron, stainless steel or plastic. Particular attention should be paid to the maximum permissible content of impurities and solid particles, in which the unit will operate without failures.

The quality of particle grinding depends on the design of the impeller: some models are equipped with cutting edges, while others are equipped with special knives

It is very convenient if the model provides for self-cleaning of the grinder, which significantly extends the life of the pump.

Some other criteria apply to devices intended for irrigation: tech / nasos-dlya-poliva-ogoroda.html

Among foreign manufacturers of domestic pumps the most popular are: Grundfos, Nocchi, Pedrollo. The main advantages of their units are ease of use, small dimensions, as well as excellent value for money.
