In the country, they turned off the light, there is no water. And you only need two buckets to water a garden of radishes. This is where the hand pump for water comes in handy. This is a very useful thing in the household. They swung five to ten times, water and went - artesian, clean, drinking.
Simple construction
Cylinder with internal piston and valve. Below is another sash that opens under the pressure of water. When the lever of this device moves downward, the piston rushes upward, creating a vacuum inside the cylinder and the riser. Water rises under pressure, opening the bottom valve (sash). The cylinder is filling. Raising the handle up, you close it by moving the internal contents down. At this time, water passes through the middle leaf into the upper part of the cylinder, which is above the piston. When you lower the lever again, the jet goes into the nozzle. It is located on the top, side. In the good old days of this type, a manual piston pump for water was called a "column".
Types of pumps
When the groundwater is shallow, it’s easy to dig a well or well, about 7 meters deep. Manual piston pump for water - a reliable device with good performance. Just mounted.
The mechanisms improved with two pistons do not have idling, as they pump liquid during any movement of the handle. Such pumps are used when filling barrels in garden plots, bath tanks and showers. You can use them to pump water from the basement.
It is better to choose a hand pump for water with a cast iron body and pipes without plastic knots. The price is higher, but the design is easy to repair, it will last forever.
Modifications of pumps for water intake from an open reservoir and from a well may differ slightly.
What to look for
- What kind of water will be supplied. Well, if it were clean, without sand, dirt. Perhaps it will be sea salty. For silt water, a larger fraction of the fractions in the pump is provided.
- What is the depth of the well. If the water is very deep from the surface of the earth, buy a deep immersion column.
- For industrial or agricultural large-scale works, a more powerful manual water pump is required.
Dimensions
A small pump weighing about 4 kg has the following measurements: 250 * 140 * 135. The water flow rate is 7-8 l / min. It is inexpensive - about 4000 rubles. There are more massive columns of 10, 15 kg, up to 30 and above. They pump liquid at a speed of up to 100 l / min, the size, respectively, is larger and the price is 16,000-20000 rubles. The water pressure in all brands of devices is the same - 25 m.v.st.
Homemade device
For the "Kulibins" it costs nothing to make a manual water pump by themselves. The body is made of an OPG fire extinguisher or a piece of pipe of a certain diameter. A piston of the appropriate size is selected, for example, 60-80 cm long, with a diameter of 80 mm. Covers fit metal or plastic, for one season it is enough and wooden. As an inlet pipe, a very rigid hose is needed that would not be squeezed when water is sucked. You can adapt the drive from the wind or put an external combustion engine and turn the manual pump for water into a semi-automatic. Such a unit will cost you much cheaper.
