The owners of suburban areas often face the problem of pumping dirty water. To clean the well of sand and clay or to remove the dirty water from a decorative pond with any of these problems help to cope pumps for pumping water. Especially valuable the presence of such aggregates in the economy, when flooded basements, or does the process of melting snow in the spring. Unlike wells and downhole assemblies, pumps for pumping water is able to pass small stones, solid particles and fiber, making indispensable in the conduct of country farms.
Surface units are designed for loosely-contaminated water. They are capable of passing solid particles, the size of which does not exceed 1 cm.
Depending on the method of intake water country water pumps are divided into two categories: surface and submersible
The main advantage of these pumps is the ease of installation and ease of operation. The undeniable advantage of surface pumps is the ability to move them around the area, taking in the room in case of bad weather. This is very convenient because a universal unit can be used for different purposes. To run the pump enough to place it on flat ground, put it in the water intake end of the suction hose and then connect the device to the mains. Submersible units themselves disconnected in case of overheating of the motor, they also have protection from electric shock and therefore do not require additional maintenance. Suction depth of surface units is limited: to run without overloading, the majority of models may at a depth of about five meters.
In the process of working with this unit on the bottom of the reservoir immersed only the input tube. The device a short distance from the fence, setting it on a flat hard surface
Most of the models surface water pumps for pumping water not have a strong capacity: it is better to buy for infrequent use. This unit will successfully cope with pumping water from the basement and watering the garden held no more than once a week. But in daily use it quickly breaks down.
The sale can be seen surface units in metal and plastic cases. Metal, though, and humming while working, but not afraid of blows and have a long service life. Plastics are much cheaper and are much quieter, but still not strong enough.
Council. To reduce the level «growl» the pump during pumping the water, you need to put it on a rubberized Mat that will suppress vibration.
Because the process of pumping water the unit should be installed in the street, pumping out the water when the temperature is below zero, there is a risk of freezing the system. Therefore, in the cold season, the surface pump is better positioned indoors or carefully conceal.
Unlike surface pumps, submersible units have higher capacity, greatly expanding the scope of their application.
Submersible pumps can be installed not only in wells and artificial wells, but in open water
Powerful devices able to pump out highly contaminated water a composition which contains coarse particles with a diameter of from 1 to 5, see Devices equipped with large working chambers, through which the polluted water together with the debris is pumped freely, not clogging up the system itself.
Depending on the performance and capacity of the device distinguish between domestic and industrial pumps. For suburban use, it is suitable for household pumps for pumping water. Such aggregates, grinding sludge and plankton of the reservoir, will provide additional vegetable garden natural fertilizer.
Wanting to buy a universal water pump that will successfully cope with domestic sewage and dirty water, should give preference fecal pumps. Their main purpose is pumping the contaminated water, which are solid wastes and extra long staple inclusion.
Fecal pumps can drive in the water with the inclusion of particles whose size is 10 centimeters in diameter
A distinctive feature of these assemblies from submersible systems is the presence of a chopper, which is able first to grind all solids into smaller particles and then send them to the system for further pumping.
In the manufacture of sewage pumps are used high-strength materials having increased resistance to aggressive environment, which is not terrible chemical reaction of decomposition. The service life of these units for over 10 years.
When choosing a submersible pump, the main thing is not to miscalculate, and so you need to consider several key points:
- The scope of application of the pump. Choosing a pump, you need to start on what functions it will perform. Planning to use the unit only as needed to clean flooded areas or watering the garden from a nearby pond, enough to purchase a pump with an output of 120 liters per minute. If the pump will be installed in the drainage system, it is better to buy 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 quantity of the fluid for one minute.
- The location of the suction valve. Units, suction device which is located in the lower part of the body, capable of rapidly and almost completely to pump water from the basement or tank. But placing such a unit on the bottom of the pond, you should be prepared for the fact that, in the process pumping, together with water, it will take a large amount of silt. Therefore, for these purposes it is better to choose models with the placement of the suction device in the upper part of the body, or to mount devices on a special stand.
- Float automatic shut-off. The presence of a float responsive to the level change of the water and giving the command to turn off the engine, greatly facilitates the work with the unit. Automatic system to prevent overheating of the motor in the case that after pumping all the water the pump will work «dry». Potravin a little more at the pump, equipped with system of automatics, the owner will not have to spend time near the working device, pending the completion of the process.
Since the pump for pumping water would mainly work in a hostile environment, when choosing a model one should pay attention to the material construction of the body and main parts. The highest resistance to external influences are cast iron, stainless steel or plastic. Special attention should be paid to the maximum allowable contents of impurities and particulates, in which the unit will operate without interruption.
The quality of the grinding particles depends on the design of the impeller: some models are equipped with cutting edges, others are special knives
Very convenient if the model provides a self-cleaning shredder, which significantly extends the life of the pump.
Among the manufacturers of household pumps are the most popular: Grundfos, Nocchi, Pedrollo. The main advantages of their units is the ease of use, small dimensions and excellent value for money and quality.
