How hand pumps for a well are arranged and work

It is easier and faster to use electric pumping stations, but this is not always possible. In this case, the only way out to solve the problem is to install mechanical equipment to raise water to the surface from wells. Hand pumps are especially relevant if the owners spend little time in the house and the need for water is not so great.

Scope of the manual submersible pump

The main purpose of operating pump-type units is to pump water from the depths to specific points, for example, a garden, a house, a garage, a bathhouse, etc.

All private houses are divided into three large groups: periodical, seasonal and permanent residence. Not all of them have electricity, and some are supplied, but not on a permanent basis.

Summarizing the above factors, the following conclusions follow:

• In houses intended for permanent residence, there is always electricity, therefore, it is preferable to install electric pumps to supply water. The manual model is only an auxiliary device.
• When it comes to seasonal buildings where no power lines are connected, installing a hand pump is the best option.

You can draw water from containers with buckets, but the pumping station, albeit manual, is more convenient.

Types of pumps, their principle of operation and design

If the liquid mirror is located at a shallow depth and there is no need to purchase expensive electrical counterparts, you should pay attention to mechanical pumping stations.

By the principle of their design, well pumps are different.

• Diaphragm units are used to pump not only clean, but also dirty liquids. Mechanisms do not jam due to the self-cleaning valve equipment. There are no rubbing parts in the design that could wear out quickly. This is good for the duration and productivity of the work. The suction height of the liquid is no more than 6 meters.
• Vane - self-priming structures (up to 1 meter), which consist of several valves, a body, a shaft, a wing, a suction element and a lever. Designed for pumping liquids without solids, edible oils, alcohol and liquid fuels. In the Russian market, the cost starts from 4000-5000 rubles.
• Sucker rod pumps are capable of lifting liquid from a depth of up to 30 meters. They have a similar design and piston. The only difference is the more elongated piston shape. The disadvantages of the unit are bulkiness, as well as the likelihood of the rod breaking.
• Reciprocating pumping stations create outlet pressure. Housings are made, as a rule, of stainless steel, and other parts are made of fluoroplastic. They will not be able to pump water from deep wells, but they can easily replace surface electric pumps.

Hydraulic pumping stations are famous for their compact size. The weight of the structure is only 4 kg.

Criterias of choice

For many, the fundamental criterion for choosing pumping equipment is an acceptable cost. But this is the wrong approach, at the time of purchasing a hand pump, the following criteria are important:

• Well depth.Conventionally, mechanical pumping stations are divided into two large groups: devices designed to lift liquid from a depth of up to 30 meters, and mechanisms operating at a depth of up to 6 meters.
• Borehole diameter. Experts strongly advise drilling a hole over 4 inches in diameter. This will allow any pump to be installed in the future.
• The degree of contamination and the nature of the liquid. There are modifications designed to work with polluted and clean water, you can find out about this in the attached documentation.
• Objectives. Due to technical limitations, not every mechanical pump will satisfy all the needs of the owner.
• Time of use - this moment is important, since there are units that are designed only for operation in a warm period. If water supply is needed all year round, it is worth purchasing a more expensive model.

For some people, the attractiveness of the unit plays a role. Most of the housings are made of cast iron and have good looks.

Installation of a hand water pump for wells and wells

Difficulties in installing a hand water pump should not arise, the procedure is simple and does not require special skills.

To install a manual pumping station, you need to perform the following sequence of actions:

1. Check the contents, all supplied parts must be in place.
2. The pump casing is installed in an upright position so that the lower part is submerged in water.
3. If it is written in the enclosed operating manual that the device is not intended for pumping water with a high solids content, it is necessary to additionally install cleaning filters.
4. The structure must be fixed to the surface of the ground in such a way that it is strong and stable.
5. Bleed the pump so that the inside is flushed with plenty of clean water.

It is recommended to choose the location for installation as flat as possible; stones and other debris are first removed.

Advantages and disadvantages

The mechanical method of raising water has a number of advantages and disadvantages. Before purchasing a manual pumping station, you need to carefully read them.

Device advantages:

• Easy to install, operate and maintain.
• Saving money. To raise water to the surface, a person makes physical efforts; an electrical connection is not required.
• The structure consists of working units, which can be replaced with new ones if necessary. Thanks to this feature, it is possible to maximize the life of the device.
• The cost is affordable, especially in comparison with electrical counterparts.
• The body of the hand pump is made of high quality stainless steel or cast iron.

Users note the following disadvantages:

• Poor performance and power. In comparison with automatic counterparts, the mechanical device shows modest results in lifting liquid to the surface.
• The need to exert physical effort to lift fluid. The process takes place by pressing the lever trigger mechanism.

Borehole hand pumps are in great demand among Russian consumers, since they are often the only way to organize water supply.
