The main question for people who are going to buy equipment for water supply is what to choose: a good submersible pump or a surface pump station. There is no definite answer, since several factors affect the operation of an aggregate at once. If you study them in detail, you can precisely decide what to buy.
The main differences between the pump and the pumping station
To make a choice between a pumping station or a submersible pump, you need to consider how much time it is planned to operate the device: it will work only during the summer season or the owners live in the house permanently. If people rarely come to the cottage, it is advisable to clean the equipment so that they do not steal it. Dismantling the submersible unit is easier than moving the pumping machine with all pipes and hoses to another room.
The main differences:
- During the operation of the stationary pumping unit, water is pumped into the accumulator. When the desired pressure is reached in it, the relay turns off the device, and the liquid passes to the consumer. A hydraulic accumulator is a piece of equipment associated with other nodes. There is no water supply in the submersible pump; it is switched on every time a tap is opened at the top. To operate the unit less, it is necessary to attach a storage tank to it separately. It can be made large - up to 200 liters, in which case the pump will turn on once a day.
- A submersible device consumes much less electricity, since it does not spend it on suction, as the station does.
- The station can be heard in the living room, if it is located nearby, the submersible unit is difficult to hear, even if it is behind the wall, because the liquid reduces vibration and the engine is located in the water column.
- The advantage of the submersible device in depth, from which it is able to raise water to the surface - up to 50 meters. The station pumps liquid from a maximum of 10 meters.
- The cost of a pumping machine is higher than a submersible pump.
Both varieties have advantages, but also disadvantages, but each one is designed for an individual situation, so you need to approach the choice consciously.
It is more difficult to choose between a surface pump and a surface pumping machine. Here, the principle of operation and the environment in which the devices will work come to the fore.
The vortex surface pump is not used to pump dirty liquid or water with sand, because solid particles destroy internal parts and damage the unit. If the device is purchased for drainage or pumping water from a reservoir, it is better to use centrifugal or submersible equipment.
According to experts, there are more common characteristics between stations and conventional units. When choosing between a pumping station or a pump with automatic equipment, they look at the efficiency: if it is the same, there is no difference in operation.
The difference between a pumping station and a surface pump:
- price - pumps are available without a storage battery, therefore, are cheaper;
- the station is designed for stationary use, and the pump can be moved;
- station is larger;
- manufacturer's brand: often simple pumps without a drive last longer than a purchased stationary installation of unknown origin.
It is not recommended to save on equipment, the comfort of all residents will depend on the quality of work of which.If there is no suitable pumping surface device on sale, it is better to buy a pump from a German manufacturer, install a storage tank and reduce the switching frequency to 1-2 times per day.
Criterias of choice
The main criterion is engine power. For a family of 3-5 people, you need to buy an aggregate capable of producing 3-5 cubic meters of water.
The depth of the well or well is taken into account. If the water is always at approximately the same level, you can take the station. But if the well becomes empty during hot weather, you will need a submersible pump operating at a depth of 50 m, so as not to be left without water in the summer.
The height of the water column is important when the equipment is far from home. The indicator is calculated by the formula, only then they go to choose a device with the given parameters.
In what situations should you opt for a pump
If the store does not have a pump station with the necessary characteristics or the principle of operation, or its manufacturer does not inspire confidence, choose a pump. If it is German, Italian or Danish manufacturers, there is a chance that the units will last at least 7 years without repair.
If in the summer the whole family moves to a fully equipped summer house, where it is planned to include plumbing fixtures and kitchen appliances, you will need a pump, which, with the onset of autumn, can be removed and hidden in the house.
If the house already has a stationary device, and the pump is needed for street work or a garden that is located near a pond, there is no need to overpay for the station.
In addition to drinking water, you can pump sewage or drain the lowlands. For such work, drainage or fecal pumps with a completely different principle of operation are suitable.
If the pressure of the pumping station located in the house is not enough to irrigate the site, you need a second instance - more powerful, which will work from another water intake. To dismantle and transfer the station is long and inconvenient. A small pump weighs much less.
When to choose a pumping station
Service centers for the repair and replacement of parts of pumping equipment may not be available in all cities. This is an important point if, in addition, you buy a Chinese unit, which is likely to break more often. Parts are cheap, but it's hard to find them quickly. It is not always possible to wait until an order arrives from the Internet, therefore it is better to buy an aggregate of a well-known manufacturer, whose service center is in the city.
Submersible equipment is more complex. If you have to install it yourself, but there are no necessary skills, it is better to choose a pump station with a simplified connection method.
At a cost, a pumping machine will be cheaper than a submersible pump of the same power, about 2-3 times. Among similar units, you need to choose a manufacturer. Russian products are not much different from their Western counterparts, so you should take a closer look at them so as not to overpay.
It is worth considering in what conditions the equipment will work, how much the room is insulated. Another nuance regarding the operation of the pumping station: the hose must not be placed on the suction because it sticks together during operation and can burst in winter at low temperatures. For surface pumping equipment, a plastic pipe is needed so that the units work without interruptions.
