The electricity was turned off at the dacha, there is no water. And you only need two buckets to water a garden of radishes. This is where a manual water pump comes in handy. This is a very useful thing in the household. They pumped five or ten times, and the water went - artesian, clean, drinkable.
Simple design
Cylinder with internal piston and valve. Below is another sash that opens under the pressure of water. When the lever of this device moves down, the piston rushes up, creating a vacuum inside the cylinder and riser pipe. Water under pressure rises, while opening the bottom valve (leaf). The cylinder is filled. Lifting the handle up, you close it by moving the inner contents down. At this time, water passes through the middle flap to the upper part of the cylinder, which is above the piston. When you lower the lever again, the jet goes into the nozzle. It's on the top side. In the good old days, this type of manual piston water pump was called a "column".
Types of pumps
When the groundwater is shallow, it is easy to dig a well or a well, about 7 meters deep. Manual piston pump forwater is a reliable device with good performance. Easy to install. Advanced dual-piston mechanisms do not have idle strokes, as they pump liquid with any movement of the handle. Such pumps are used when filling barrels in garden plots, bath and shower containers. You can use them to pump water out of the basement.
It is better to choose a hand pump for water with a cast iron body and pipes without plastic assemblies. The price is higher, but the design is easy to repair, will last forever. Modifications of pumps for drawing water from an open reservoir and from a well may differ slightly.
What to look out for
- Which water will be supplied. Well, if it was clean, without sand, dirt. Perhaps it will be sea s alty. For silty water, a larger fraction is provided in the pump.
- What is the depth of the well. If the water is very deep from the surface of the earth, buy a deep well.
- For industrial or agricultural large-scale work, a more powerful manual water pump is required.
Sizes
A small pump weighing about 4 kg has the following dimensions: 250140135. Water supply rate - 7-8 l / min. It is inexpensive - about 4000 rubles. There are more massive columns in 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 16,000-20,000 rubles. Water pressure in all brands of appliancesthe same - 25 mw.st.
Homemade device
For the "Kulibins" it doesn't cost anything to make a hand pump for water. The body is made from 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. Metal or plastic lids are suitable, wooden ones are enough for one season. A very rigid hose is required as an inlet pipe, which would not be squeezed when water is sucked in. You can adapt a wind drive or put an external combustion engine and turn a manual water pump into a semi-automatic one. Such a unit will cost you much less.
