Garden, garden, flowerbeds, lawns - everything needs regular watering. Regular pumps for water supply with this task are not always coped - there are its own characteristics in watering, because the pump for watering the garden, garden, flower garden and lawn are selected separately using a completely different approach.
For watering of the garden, it is required to competently select the pump
Water source and watering pump category
The choice of pump for watering the garden largely depends on the water source. It can be:
- well;
- well;
- river, pond, swimming pool;
- Capacities and barrels.
In the case of a well and well, specifications will be technically characteristic - it is necessary that water with due pressure be delivered to the watering place. Models - in principle any. Choose your taste.
If we are talking about a river of a pond or pool, then the requirements of water pollution are added to the specifications. If in the pool water can still be considered conditionally clean, then in the river or pond, pollution will be enough, so that the usual equipment will not fit. Ordinary models in this case do not fit, as they are intended for clean water. Polluted water can download drainage and garden pumps. Here are among these categories and it is worth looking for a pump for watering the garden in this case.
For watering of a vegetable river or pond fit all pumps
When watering from tanks and barrels, the task becomes even more interesting. Water in this case is also not clean, so the drainage pumps are suitable, but not any, but the most low-power. It's all about the volume of water, which may be contained in the barrel. With a large productivity of 200 liters of water, the average power pump pumps in 1-3 minutes. You will have time to pour at this time quite a bit, but there are no more water. Therefore, the best in this case is the most low-power (they are part-time and the cheapest). Only when buying, pay attention to the pump to walk with a float water level sensor. If water remains very small, this sensor will turn off the power.
Some firms produce special pumps for barrels. They are just distinguished by small productivity and the ability to swing polluted water, have small dimensions and weight, but at a price more than similar drainters. But the barrel pump for watering the garden is compact and light.

By the way, to solve the problem with quickly ending water in a barrel simply. On the site they are usually several. Just above the bottom level, you can boil the fitting with the cranes and connect all the barrels of pipes. So it is possible to swing water from all the barrels without shifting the hose.
Types of pumps, their advantages and disadvantages when used for watering
Choosing a pump for watering the garden is not easy - it is necessary to determine many parameters, take into account the features of pumps and water sources. It is necessary to choose such a "pair" so that you can be comfortable to water, and the equipment worked in a normal, not an emergency mode.Submersible
Submersible pumps can be used to pump water from any source of sufficient volume - well, wells. To swing out of the pond and river, even with sufficient amount of water, it is problematic - water is not clean, and ordinary models are only with her and feel fine. With a very big desire, you can make a camera-filter in which the pump itself is placed. But this is also a controversial version - the walls of the chamber can break or score.
In wells or wells, you can use both vibration and centrifugal submersible pumps. The difference is that the centrifugal can "deliver" water over long distances and raise from large depths. Vibration has more modest characteristics, less resource, more demanding on water purity, but the price of them is significantly lower. This explains their popularity.

Submersible pumps There are different types (vortex and vibration), it can work with different water - clean, dirty and very dirty
As for the river and the pond, there were already tanks. In the barrel or eurocub, the centrifugal unit will not shove at all - it rolls it out in a few seconds. The vibration will create a very strong roar, even "pull" the water will be for several minutes. But the roar is worth such that the neighbors can come. So, too, not very suitable for such working conditions.
So, for the submersible pump for watering the vegetable garden, if the water source is a well or a well without sand.
Drainage
Drainage pumps are mostly represented by submersible type. What distinguishes them - the ability to work with muddy and polluted water. In this regard, drainage pumps are used just for watering the garden from open sources of water - river, ponds, etc.
But only remember that dirty water is not a row and tina, but water contained solid particles with dimensions of no more than 5 mm. But some manufacturers determine other frames for their equipment - often the particle size should not exceed 3 mm. Therefore, if the reservoir is polluted strongly, the same camera with walls from the grid, which will be delayed large contaminants. If you are reluctant with this, and the water is really dirty, you can use not a drainage pump for watering, but fecal. He can even download Il. There are models, with a shredder that falling large objects in a second.
Drainage submersible pump can feed water from river or pond
So, the drainage pump for watering the garden is good if water has a significant amount of impurities, but they are all not more than 3-5 mm. For large contaminants, it is more expedient to apply a fecal unit.
Barrels
Another type of submersible pumps designed specifically for watering from small tanks - barrel (pocket) pumps. They have a small performance, low power and dimensions, low noise. With a decrease in the water level in the tank, they gradually raise the pressure so that the pressure at the outlet remains stable. In general, such a pump for watering the garden is a good acquisition, but ... if the price arranges you.
Pump for irrigation for barrels is very convenient and quiet, but prices do not please
The inlet of the barrel pump is closed by a mesh - a filter from large contaminants. But this is not always enough. If there is a lot of dirt in the barrel, make an additional filter. You can even lower a piece of gauze or other mesh fabric (old tulle, for example), consolidate it so that it does not take a little to the bottom. In this cloth you can lower the unit. In this case, it will work longer without maintenance (it is necessary to periodically clean from the dirt that accumulates inside). The fabric inside during operation will not tighten - there is a grid, so the option is quite capable.
Outdoor
For watering of the garden from the river or pond, external pumps are more suitable. Only the hose is lowered into the source, and the unit itself remains on the surface. Just keep in mind that the hose must be reinforced - the usual simply flattens the negative pressure created during operation.
The disadvantages of this type of equipment include their weight - they are usually quite severe, which creates difficulties in carrying. Their corps are made of steel or cast iron, and it is clearly not easy. To eliminate this disadvantage, special garden pumps were invented. Their corps are made of plastic, which makes them much easier - even a woman can cope with the carrying. In addition, garden pumps are better adapted for pumping not quite clean water. So for watering the garden from the river it is a good choice.

All are good outdoor pumps, but to fill them before starting the work - not the most interesting occupation
In working with outdoor suction pumps there is one nuance: in order to launch them, the pump itself and the hose itself will be filled with water. The outer pump for watering the garden by the method of work can be self-priming, then "refuel" need a little - only the container in the pump, and this is a few hundred milliliters. If the model is normally suction, you need to fill in the entire hose and the capacity of the unit, and this may be not one tens of liters. Since watering is periodic, each time it is tedious to refill such a system. Therefore, for watering of the garden, self-priming outdoor pumps are used or is looking for something else.
There are external vortex pumps (centrifugal), but they are suitable for clean water. That is, this is another option for a well or well, but with a small depth. Their plus is that they do not need to pour them, although by weight - heavy to carry from places in place is problematic.
Pumping stations for watering of vegetable
If desired, it can be used for watering the garden not a pump, but a pumping station. This, in principle, the perfect option is a stable pressure, and it can be adjusted in fairly wide limits, the motor in this is working in normal mode - turns on and disabled. But without flaws. Typically complement pumping stations with surface pumps for clean water. They will have to pour before starting, these are two. They are heavy - these are three. And the price is far from always pleases - these are four.
Pumping station for watering the garden - convenient, but not suichene
True, if desired, you can assemble the station yourself, and on the basis of any pump (drainage for example). It will take a hydroaccumulator, pressure relay, pressure gauge and a positive fitting or a set of flexible eyeliner with nuts of suitable diameters. You can also collect the entire system on polypropylene or plastic, who is used. This is not difficult, so it's realistic.
Requirements
Choosing a pump for watering, it is necessary to take into account the specifics of these devices. It is still significantly different from the working conditions of the usual, which are used for water supply at home.Performance
You can water the garden with a unit of any type, but there is one nuance: the power must be chosen so that when using nozzles (irrigated gun, sprinkler, etc.) did not break the hose. Moreover, it is not the most pleasant moment that, with a simple pricing watering, less productivity is required - a strong jet is simply wooing the soil. When using raincoats or irrigated pistols, the pressure should be more - to capture a large area.
The only acceptable output is at the output of a decent power pump to put a tee. To connect the hose for irrigation to one exit, to the second hose through the valve, which will take part of the water back to the source. With such a connection, adjusting the amount of water returned by the valve, it turns out to change the treatment of watering, and in a wide range.
Surface pumps for watering the garden in plastic cases are garden models that were developed just for these purposes.
This system is very useful when watering from barrels. When using even ordinary drinkers, barrels roll out very quickly. Such a focus with the return of water allows you to stretch the feed and pour a large area.
If you look for a pump for watering a small capacity, you will find that the units of good brands with low power find it difficult. If they are, then at a high price. But there are a lot of cheap Chinese minor pumps, which are also designed to pump dirty water. This is exactly the option that is needed for watering from barrel, pond or river. True, the percentage of marriage is high - 20-30%.

Decisions in this case are two - to buy a cheap pump, if necessary, buy a new one. The second output is to reduce the performance of a normal unit. You can do this by installing a smaller diameter hose. But for the pump it is bad - it will work, but the rate of wear will increase significantly. To improve the working conditions, you can lead to the point of watering the standard size hose, and only then install the adapter. It is not that the situation will radically improve, but the water consumption will be less, and the pressure will be strong - you can use sprinklers and other nozzles.
Protection against overheating and dry stroke
Since the pump is working for irrigation of the garden for a long time, and even often not at the best for it mode, the situation is quite possible when the motor will overheat. Therefore, it is very desirable to protect against overheating (thermoster). A very useful option - when the threshold temperature is reached, the power supply is simply turned off.
This float turns off the power of the pump when water becomes little
In any source of water, there may be little. Even from a well or well, it can be downloaded. If the pump will work for some time without water, it will be overgrown - water serves simultaneously for cooling the case. Therefore, they put protection from dry stroke. The most popular, simple, reliable and cheap way - float. This is a water level sensor, which, with its insufficient amount, simply breaks down the power supply. There are pumps for watering the garden, which immediately go with such a device, and if not, it can be installed independently - connecting the wires from the sensor into the gap of one of the feed wires.
Definition of parameters
As for performance, it was already determined - it is needed small - about 3-5 cubic meters per hour (it is 3000-5000 liters per hour), which is more than enough for watering the garden and the garden.
What should be considered - this is the pressure of the pump. This is the value that water can be pumped. It consists of two components - vertical and horizontal. Vertical is the depth from which water will have to raise. Here as it is, it is - every meter of depth is equal to one meter of pressure. Only in the technical characteristics to pumps there is such a line as "maximum suction depth". So, it should be more than the depth of at least 20-25%. You can take both directions, but only brand equipment, as Chinese indicators are usually overestimated.

The horizontal component of the pump pressure is the distance that the water raised to transport to the watering place (when calculating, take the long-distance point). When using an inch pipeline or hose, it is believed that 1 meter of lifting is required by 10 meters of horizontal pipeline. With a decrease in the diameter, the figure becomes less - for example, in 3/4 inches, 7 meters of pipe / hose per 1 meter of lifting are considered.
It will also have to take into account the resistance of pipes (hoses). To do this, add about 20% to the settlement value.
An example of calculating the pressure. The water mirror is located at a distance of 6 meters from the surface, they will swing from the depth of 8 m, it will be necessary to transmit from the point of the fence to 50 m. The pipe goes inch, because we consider the horizontal pressure by 10 m.
So: the overall pressure is 8 m + 50m / 10 = 13 m. We add a stock on the losses on the joints (20% of 13 m is 2.6 m), we get 15.6 m, after rounding - 16 m. When choosing a pump for irrigation We look so that its maximum pressure is at least this figure.
