The foot irrigation pump is a simple pump that doesn’t need electric power or gas to run and you can do it yourself (DIY). A foot pump is a human-operated suction pump that sits at the top of a well and is used for irrigation. It is designed to lift water from a depth of seven meters or less. Pumping is activated by pressing a pedal, which is a lever that drives a piston, creating a cylinder suction that pumps groundwater to the surface. 
The foot pump frees farmers from rainwater irrigation and helps farmers maximize yields from small plots. A foot pump can do most of the work of an electric pump, but at a much lower cost. Pumps cost between $20 and $100 including installation. Because it does not require fossil fuels (it is powered by the weight of the operator's body and leg muscles), its running cost is also lower (50%) than an electric pump. It can pump 5-7 cubic meters of water per hour from wells and boreholes up to 7 meters deep, and can also be used to pump water from lakes and rivers. Many floor pumps are made locally, but they can be difficult to produce consistently without highly skilled welders and production equipment. Farmers most often use foot pumps on small plots, usually around an acre. They are also utilized in destitute nations and small villages such as: towns in Africa, little farmers in Asia, and anywhere else where cash is an issue. 
Compared with barrel irrigation, the foot pump increases the growing period, expands the types of crops that can be planted, improves the quality of crop planting, and greatly increases the land income of farmers.
foot irrigation pump diy
The design of the foot irrigation pump is simple and it means you can do it yourself (DIY). The treadle pump has some components.
- Cylinder: The treadle pump uses two cylinders (one for each pedal) with an 80mm diameter cast steel cylinder.
- Pump manifold: The manifold connects the inlet and outlet pipes to the cylinders and houses the check valves (two in the suction pump and three in the discharge pump).
- Due to the nature of the suction pump outlet, an outlet side is not required.
- piston assembly: The pistons move up and down inside the cylinder and it is important that they remain vertical in the cylinder when the pedals move up and down (photo 1), this is done to maintain a good seal between the piston and the cylinder wall.
- the piston rod is connected to the pedals (Figure 2). The piston rod is made of steel bars because it is a very strong and generally available material.
head = 8 feet Stroke length, L=200 mm Cylinder diameter, d=80 mm Piston area, A = 5.026x10-3 m2 Theoretical flow, Qthe = 25 l/min
- check valve: As mentioned earlier, the suction pump has two check valves and the discharge pump has three.
- Due to the positive and negative pressure created during pumping, the valve only allows water to flow in one direction when opening and closing.
- Pedal: The pedals must be strong enough to withstand the force applied by the operator and stiff enough to transmit the force applied to the piston without appreciable deflection.
- Depending on the level of leverage used, the pedals can be hinged at one end or in the middle, with the other end supported by ropes and pulleys or seesaws.
foot irrigation pump electric
The food irrigation pump is designed to be used in remote places where there is no electric power. A foot pump is a human-powered pump designed to irrigate small plots of land. According to Zambia's International Development Enterprise (IDE), the pump can add more than $100 a year to farm income. According to the FAO, irrigation can increase crop yields by 100 to 400 percent. This article assesses the contribution of foot pumps to the welfare of smallholders. The floor pump is more efficient and user-friendly. The pump can be used comfortably. The farmer stands on the pedals and pushes the plunger up and down the pedals, where he raises enough water to irrigate his land. Foot pumps provide access to water, freeing farmers from the vagaries of nature, unstable electricity and expensive diesel. Foot pumps are portable systems that can be moved from place to place, as close as possible to the water source (boreholes, boiled wells, ponds, canals, etc.). 
The foot pump must be properly adjusted and maintained to efficiently pump water up to 5000 liters per hour without fatigue, and it must function in a natural way like walking. Conversely, low-cost foot pumps could have a significant impact and significantly improve agricultural and food security in the region. Foot pumps make it easier for farmers to get water for their fields or vegetable gardens. Inexpensive foot pumps could replace the age-old practice of irrigating very small plots of land using bucket-lift technology, which is slow, cumbersome, and labor-intensive.
foot irrigation pump gas
The only power that a foot irrigation pump requires, is human power. No gas or electricity is needed. Foot pumps are human-powered devices that provide an alternative method of pumping between the simple rope and bucket method and more complex gas pumps. 
These pumps, originating in Southeast Asia, have been modified to suit African conditions and are available in different configurations depending on the desired drainage condition. Although many factors can affect the performance of a floor pump, the piston seal which creates suction pressure in the pump is a critical component of the pump and has a significant impact on its operation of the pump. Several studies have shown that African farmers who use foot pumps can reduce poverty compared to non-adopters. 
Although foot pumps have been used successfully in some cases to increase farm income, they may or may not be appropriate for every culture and context. One study found that at low flow rates, adequate irrigation required longer pumping times and that pumping exhaustion was attributable to the farmer's spouse's sexual inactivity, whether or not there was a real correlation [14]. This example shows that the design and operation of foot pumps must take into account technical and cultural positivity for the technology to be widely accepted.* 
foot irrigation pump in lake
to elevate water from the lake or any other water reservoir a foot irrigation pump can be used. One of the most commonly used water reservoirs is the tank. Water storage tanks come in a variety of shapes, sizes, and configurations for a variety of uses in the water treatment industry. From small 5-gallon reverse osmosis tanks neatly stored under the sink to towering 120-gallon well pressure tanks, water storage tanks are an integral part of many home water systems. 
Large outdoor atmospheric tanks can store thousands of gallons of rainwater, well water, or water used to fight fires. These tanks are often fitted with UV inhibitors, which prevent sunlight from promoting the growth of algae and bacteria in the tank. Thermal expansion tanks prevent leaking and bursting water heaters on closed water supplies. A storage tank can store clean water in a reverse osmosis system until the home or business begins to need it. Water is pumped into a tank from a source, such as a well or a reverse osmosis system. 
The tank will accumulate water until it is full. When you need water, whether it's to fill your glass with clean water, take a bath or irrigate your fields, the storage tank gives you instant access. The water storage tank is usually a pressure tank or an atmospheric pressure tank. Point-of-use applications, such as reverse osmosis storage tanks, typically use pressure tanks. Atmospheric tanks are often used in outdoor applications or large-scale municipal water storage operations.
foot irrigation pump low pressure
the pressure of the foot irrigation can be low or high as it is powered by human motion movement. The function of the treadle pump is to rest the operator on two wooden or metal pedals, called pedals, which are connected to two pistons mounted in separate cylinders. 
Then use a stepping motion to move the pedals and pump. The pistons are connected by ropes or chains on pulleys or pivot points, allowing one piston to descend into the cylinder while the other is pulled up as the operator begins to move. The weight of the operator's body is the main force driving the movement of the piston. During the upstroke, the piston rises in the cylinder, creating suction pressure in the cylinder due to the piston seal between the piston and the inner wall of the cylinder. This suction pressure causes a one-way valve under the pump body to open the cylinder, which in turn sucks water into the cylinder as the water flows out of the pipe connected to the pump body at one end, and the other end is in the source water. On the downstroke, the water inlet valve closes and water is expelled from the cylinder. 
foot irrigation pump medical
By increasing the usage of foot irrigation pumps around the world, the medical aspect of that becomes important. The operator of the treadle pump can be a man, a woman, or a child, so the parameters associated with the operator can vary considerably, namely weight, height, and morphology. A pedal is a flexible machine that can easily adapt to different people, even children. The operator can choose the position of the foot relative to the pivot point, thus modifying the cadence and the force of the foot. Lower cadence equals higher power and lower stroke, which is more than enough for heavier people. On the other hand, higher tempo, higher hit, and lower power are more than enough for youngsters. Recommendations for cadences below 60 cycles/min and a foot stroke between 100 and 350 mm can be found in the literature. The leg movement is similar to a combination of crawling and walking, so it is easily learned and repeated sequentially in a mechanized fashion. 
However, when using an isolated number of muscles or when the body is forced to work in awkward anatomical positions, the human body tires quickly. In addition, the user should not transmit more than 50% of their body weight to the pedals for long periods. In the short term, this limit can be raised to 70%. Since the treadle pump can be used by different types of operators (men, women, and children), it should be designed with resistance between 15 and 50 kgf. The angular position of the legs depends on the distance from the feet and represents another important ergonomic parameter. In fact, the pedals must be large enough to accommodate different operator heights and allow the selection of the best position. In addition, the relatively large pedal allows flexible adjustment of the angular position of the foot. On the other hand, larger feet would add weight and negatively impact pump portability, another key design parameter.
