Water - is the main natural wealth.But not everywhere and not always people who can connect to the centralized water supply and use of this blessing.In such situations we have to build independent water supply, which are required for the functional pumps.These devices are designed for transporting fluid under pressure.They are widely used, and their diversity pleasantly surprised and puzzled at the same time.Especially pumps needed cottagers and residents of the private sector.Thus, for example, is very popular with the water pump for the cottages, which pumps water from deep wells and the nearby open water for watering gardens, because in this way can avoid long hours of physical labor.


Types and features of pumping equipment ↑

Depending on the conditions in which it will be operated, the pump can be submerged or superficial.If you have a centralized water supply is often used high-pressure water pumps, which are connected to the water to create a high-pressure water jets.

Arrangement of the surface of the pump
Arrangement surface pump

All water pumps for the home or garden are arranged on one common principle.

In operation, the pump creates a vacuum within themselves, whereby fluid from the reservoir is drawn into the vacuum chamber, after which the force is pushed out and the pipe is directed to the destination.Depending on how you create a vacuum are following principles of the Pump:

Vortex Pump: pluses and minuses ↑

operation of these pumps is based on the rotation of the vortex wheel - a flat disc with radial blades on its periphery.During wheel rotation water flows into the cavity within the housing and is pushed out by rotation of the blades.

  • pump mechanism is very "do not like" suspended particles that may be in the water.

Therefore, these pumps should be used cautiously when pumping water from contaminated waters.


  • high suction capacity and resistance to air bubbles occurring in the "feed" the pipeline.

Solenoid (vibration) Pump ↑

main element - the electromagnet.During feeding the coils of an electromagnet AC voltage it attracts the armature, and by changing the polarity of the armature returns to its original position.

Thus, during one second a hundred vibrations anchor.The same vibrating piston associated with the anchor.Since water is an elastic medium, because of the vibrations begin fluctuations and its excesses are pushed to the discharge nozzle through the valve.


  • lack of rotating components and motor.

Reliable and simple centrifugal pump ↑

This pump under the action of the blades of the impeller on the water there is the centrifugal force that creates the movement of the liquid and the desired pressure.

These household water pumps produce both submersible and surface types.Centrifugal water pump are available with vertical or horizontal placement of the output shaft.

Hand water pumps ↑

investing a minimum of means, you can still provide your summer cottage or garden water.If the demand for water in the area is low or there is no electricity, you can use the hand-pump water.

These water pumps are used to give most people who have low incomes and in areas where electricity supply is carried out with large faults or not at all.In order to bring this type of device is only required by a brute human strength.Summer residents use water pumps to irrigate their plots.

Hand pump
hand pump - a very common and versatile option

The most common among these models is the piston pump.The fluid is moved by the suction piston and the pressure difference in the cylinder.In one cycle is fed from 0.5 to 2 liters.The depth with which it is possible to pump water - up to twenty meters.

second type - vane pump.He has a special blade that is driven handle.It is compact piston, but less than the feed rate - to 1.5 liters per cycle.But the depth of pumping is the same - to twenty meters.

What pump to choose?↑

Summarizing all the above, we note that the choice of the pump is completely dependent on in what conditions will operate that device.Surface pump select or define an immersion depth of groundwater.Based on the purity of the fluid selected swirl or vibrating pump.If the plumbing is chronically low blood pressure, then install it high pressure water pump does not make sense, it is quite portable pump.Also at work is very important to remember that the electric water pump directly with water.In most cases, the pumps must be properly grounded body and three-pole plug for grounding.

How to make water pump ↑

If desired, you can make the water pump by hand.It turns a simple pump for making a lot of effort is needed.Schematic representation of the device represented in the figure.This simple pump can pump water from nearby sources.For its production will require

  • Corrugated pipe
  • bracket
  • sleeve valves

tube is suspended from the bracket and the other end is attached to a floating log.On both sides of the pipe sleeves with closed valves.Even small wave motion will operate pipe - accordion.The more compression will occur and unclamping, the better it will work this homemade pump.Note that when the wind of 2 m / sec, in the river undulations begin to swing the pump and pump assist him to twenty-five tons of water per day.

If corrugated pipe made of brass, the weight of the logs should not be less than sixty kilograms.For a homemade pump did not work one day to the lift limiter is attached to a ring through which the bolts are tightened.Limiter with bolt hold-lift in the original position and allow it to be rotated only in a horizontal plane.Plugs are screwed into the lugs and soldered to the corrugated pipe.The pump uses a homemade rubber valves.When the timber is in the correct position, it pulls on the tube and remains strictly perpendicular direction.

Repair of pumps: causes, symptoms fault ↑

Modern features of electric and water supply networks, as well as difficult operating conditions lead to various malfunctions of pumping equipment, shown in the following:

  • unplanned vibrations of the pump unit;
  • high noise levels;
  • increased operating currents;
  • pulsation;
  • pressure levels fall;
  • leakage between the flange and the pump shaft.

If seen at least one of the above symptoms, it is necessary to repair the water pump.

Among the main causes of failure of the water pump are the following:

  • errors when performing installation work unit;
  • Faults electrical installation;
  • Faults pump motor;
  • Work pump modes, which are different from the regulated.

Since the malfunction of the pump can cause a lot of reasons, the diagnosis should be carried out by qualified personnel using a range of instruments and devices.
