Manual hand pump water has been used for centuries in the rural areas of many countries. Hand-operated pumps are the most low-cost and sustainable option for supplying safe water in areas with poor infrastructure.
Hand pumps allow you to withdraw clean water that is present deep underground. They\’re ideal for lifting water from up to 80 meters deep and fulfilling the water needs of small communities.
There are different types of hand pumps. Different low-cost hand pump models suitable for most local conditions are available in the market.
If you want to learn more about hand pump technology, its types, its working, its advantages, and its disadvantages, you\’ve come to the right place.
We\’re going to go in-depth and tell you everything you need to know about hand pumps.
What is a Hand Pump?
Hand powered water pump also referred to as a manual pump or human-powered pump, is a mechanical device that is powered with human force to pump water from one place to another. Therefore, a hand pump has a manual mechanism making it a manual pump.
Water siphoning devices are used to withdraw water from underground sources such as lakes, rivers, and reservoirs and pump it into distribution or irrigation systems.
You can easily spot hand pumps at work sites or places where financial resources and electricity are constrained – places where water requirements are not excessive.
Hand pumps are easy to install and simple to operate. This is why they\’re the most ideal water-lifting technologies for rural areas in underdeveloped countries.
Human-powered pumps are known to improve the local water management systems of rural areas, hence improving the livelihood of low-income people significantly.
Hand pumps have various types. Although their designs vary, their purpose remains the same – sucking water from underground water reservoirs.
We\’ll look at different types of hand pumps in just a bit. If you want to jump straight to that section, click here.
How Does Water Hand Pump Work?
It is crucial to understand a water hand pump working to understand its usage properly.
Don\’t worry, we\’ll explain everything in the most basic way possible.
The hand-operated water pump basically sucks groundwater when the force is applied to the pump handle. Moving the pump\’s handle in an up and down motion, allows water to be sucked from the depth to the surface.
The type of hand pump used in developing countries is “displacement pumps”. Displacement pumps or piston pumps are further categorized into Lift pumps and Suction pumps.
Lift pumps are commonly used in developing countries because of their ability to draw water from greater depths that exceed the threshold of most suction pumps.
Suction pumps, however, are easier to operate than lift pumps because the pump\’s cylinder and other crucial parts sit above the ground making it easily accessible. When the pumps handle is pumped, the water gets sucked into the cylinder and exits through the spout.
But as we mentioned earlier, lift pumps are better as they can suck water from great depths compared to suction pumps. Lift pumps have their cylinder below the ground, below the water level. When the handle is pumped, instead of sucking, piston pumps lift water into the riser main until it overflows through the spout.
Types of Hand Pumps
Hand pumps are divided into different categories with different usability. Let\’s check those out, shall we?
1. Direct Pump
This is one of the common hand pump types with a hollow shaft. The hollow shaft slides on the drive shaft with respect to the motor. In such pumps, the flange has to be mounted on the face of an engine. Such direct pumps are cost-effective and have easy maintenance functionality.
2. Diaphragm Pump
Now, this hand pump differs in terms of the mechanism. It uses a very flexible quality diaphragm instead of a normal piston, as discussed earlier. Moreover, such pumps don’t require a source of electricity for the pumping mechanism.
On the flip side, you can expect to pay a lot of money for these pumps. You might also find such pumps bearing low pumping efficiency.
3. Suction and Lift Hand Pump
This hand pump relates closely to its name when we become familiar with its mechanism. Here, the fluid is to be pumped using its unique suction mechanism. Its suction capacity is equivalent to the vertical distance between the center of the pump and the fluid.
Such pumps are extremely reliable with sublime pumping capacity. Moreover, these hand pumps come in handy when lifting a substantial amount of water with small tubes.
4. Force Pump
A force hand pump features a very solid piston in its structure. It is used to force the water out to a higher position. The water from the depth can easily be transferred to the surface of the ground using such pumps.
In addition, a force hand pump works under substantial pressure when delivering the water to a high position. Such pumps can easily balance force without messing with the fluid flow.
5. Chain Pump
All chain pumps bring a traditional and manual water-lifting technique that is simple in its nature. The water lifting process is connected with the arrangement of different pulleys—one of its pulleys is submerged in water when the other moves along the pipe lifting water.
6. Deep Well Pump
As its name suggests, a hand water well pump is mostly in practice inside the wells. Such hand pumps are absolutely useful to lift a very large quantity of water to the ground. Moreover, these hand pumps are also a win when we look over the depth capacity of 15m.
A hand water pump for the well will make your water-lifting job a lot more convenient.
Advantages of Hand Water Pump
There are some very particular reasons to opt for a hand water pump in underdeveloped or remote regions. You may not see these hand water pumps everywhere, but they still hold a very incredible value for many.
- Provides an absolutely economical drinking water supply (Low hand water pump price) in rural and remote areas
- Pumps promote a simple supply of drinking water without posing a complex process demand
- It takes away the possible risks of children falling in open wells
- Hand water pump for well are extremely resistant to weather
- Pumps are very easy to install, especially for the village population
Disadvantages of Hand Water Pump
Though hand water pumps are absolutely amazing, if we look over the benefits, that\’s not all to it. There are some hand water pump problems that you must know about.
- There is no filtration for the water uplifted from the depth of the ground using these pumps
- Find hand water pump parts is not easy
- A large amount of physical exertion is required to pump the water to the surface
- It is not easy to maintain these hand operated water pump for a long-term usage
1. How does a hand water pump work?
The handle is synchronized with the pump piston using the connecting rod. So, when the handle moves upward, the piston does the same. With the repetitive up and down motion of the handle, the water gets sucked or lifted up to the surface.
2. What is a hand water pump called?
The hand pump or the pitcher pump is one of the widely used names in that regard.
3. How deep can a hand pump draw water?
A hand-operated pump can take on a maximum of 325 feet static water level. However, the depth working capacity varies for every hand pump type.
4. Is hand pump water good for health?
Hand pump water must not be consumed without giving it a proper treatment first. So, it is not healthy to consume hand pump water without treatment.
5. What are the disadvantages of a hand pump?
Maintenance and physical force exertion are some of the disadvantages of hand pumps in operations. Other than that, pump spare parts aren’t easy to find.
6. What is the manual pump?
It can be defined as a water-lifting machine capable of sucking deep groundwater and moving it to the surface. A person will have to manually operate such manual hand pumps to lift the water up the surface.
7. How do you install a hand pump?
Pumping stations can be installed by digging into the ground to a certain depth. The depth depends upon the type of hand pump being used. Also, professional aid can make things a lot easier.
