The Afripump is upgradable to communities with existing Volanta pumps. Below is the story and details of how the Afripump came to be more useful.japanese_link= Coming soon }}
====First came the Volanta [[Image:lever action icon.png|right|80px]][[Image:volanta pump====.jpg|thumb|right|200px|The Volanta Pump, created by Jansen Venneboer B.V., is a reciprocating pump driven by a large with flywheel for medium to very deep wells.

It ====The Volanta pump====The Volanta Pump, created DGIS in co-operation with by Jansen Venneboer B.V., is designed a reciprocating pump driven by a large flywheel for heavymedium to very deep wells. It uses a retractable cylinder and a seal-duty use less stainless steel piston. A crank and a connecting rod convert the rotary motion into a reciprocating action, which is transmitted to the plunger via stainless steel pump rods. The crankshaft and the maximum recommended lift flywheel run on ball bearings mounted on a plate that can be fixed to a steel or concrete pedestal. The cylinder is of glass fibre reinforced plastic with a close-fitting seal-less stainless steel plunger. The complete cylinder can be lifted from the well by the threaded pump rods, without removing the PVC-U rising main. The stroke is 70 madjustable to reduce the effort needed at deep installations.
The Volanta Pump It is not in the public domain designed for heavy-duty use and information can be asked from the manufacturer. The Volanta Pump maximum recommended installation depth is fully corrosion resistant. It is rather difficult to install and it needs extensive masonry work. Maintenance is easy so that communities can care for the pumps50 m.
====The Afripump, a Volanta upgrade====Since Pump is not in the Volanta pump needs some spares every 5 to 10 years (due to the flywheel public domain and information can be asked from the stainless steel T-piece pressure box), and because it is more expensive than other handpumps on the market, Jansen Venneboer Bmanufacturer.V. created a the The Volanta - Afripump (or in short, the "Afripump")Pump is fully corrosion resistant. The major change from the Volanta pump It is a handle instead of a flywheel rather difficult to install and a simple PVC T-piece inside the blue box, otherwise all components in the borehole are basically the sameit needs extensive masonry work. These changes greatly reduced the cost of the pump and eliminated Regular maintenance is easy so that communities can care for the need for sparespumps.
If a community would like to change any existing Volanta into an Afripump====The BluePump====The BluePump was designed by the FairWater Foundation with the input of many NGOs in Africa. A major contribution was given by Oxfam Kenya, (like when there is no regional support team to change parts that has tested the early models of the Volanta every 5 BluePump in it's handpump rehabilitation project in Turkana, Northern Kenya. After several modifications to 10 years), it can simply change adapt the flywheel arrangement BluePump for depth up to a blue box100m deep, since all the inner components are exchangeableBluePump is now considered by most international NGOs as the most reliable handpump, especially suited for deep boreholes. Also any existing Afripump One of the special features of the BluePumps is that the PVC rising main can easily be converted extended below the cylinder with a so called "Bottom Support System" (BSS). The BSS takes the heavy load of the PVC pipes to avoid that they will break due to a Volantathe pumping action.
The key success In many parts of Africa the Afripump BluePump is its also used to replace older handpumps. To make this a simple operation, the base-plate of the BluePump fits directly onto the old base-plate of the Afridev and strong construction and the fact that it needs no spare parts due to a new pumping conceptIndia Mark pumps.
====Why The key success of the Afripump won't breakdown====When other handpumps break, it BluePump is its reliability. This is often due to broken rods it's simple and strong design and broken pipes, leaking pipes, faulty piston rubbers seals, leaking footvalves or wrongly installed footvalves, etc. With the Afripump all this will not happen: i.e. the pump will not stop working due to wearing out or broken fact that it basically needs no spare partsfor many years. This means that communities have water for a very long time, simply because:at a very low price.
* The stainless steel rods have rolled threaded connections For the Operation & Maintenance (O&M) aspects of the BluePump FairWater recommends a regional approach, in which don't brake,* The heavy duty strong bearings are maintence free, lifetime 25+ years,* The rising main an Area Mechanic is made from quality BOODE PVC pipes involved already in the installation phase of the BluePump and don't break,* For deep water levels gives additional back-up technical support in case needed. Training of the Afripump has a bottom support system, * The piston has no rubber seal Area Mechanics and spare-parts supply is 100 % maintenance freeavailable with country dealers, who also have BluePumps in stock.
Optional for More info about the deep water levels is an extendable handle with a massif counter weight to compensate for the extra weight of the water and rods in the rising main. Therefore pumping remains easy, also for children, even at 80 m deepBluePump can be obtained by FairWater.
====Why the BluePump is more reliable====Most other handpumps fail due to many technical reasons: The most common problem is worn out seals and broken pipes. Other problems are leaking foot valves and broken rods. With the BluePump most of these problems do not occur due to a better design. * The stainless steel rods are 12mm diameter and fully threaded,* The heavy duty strong bearings are maintenance free and may last up to 10+ years* The rising main is from high quality PVC,* For deep water levels the BluePump has a bottom support system, * The piston has no rubber seal and is 100 % maintenance free,* The foot valve has 2 stainless steel balls for double security. The handle is extendable and can have a counter weight to compensate for the extra weight of the water and rods. Therefore pumping remains easy, also for children, even at great depth. ===Suitable conditions===
Distribution: Mainly in West African countries.<br>
Some users find it difficult to start the pump. Small children have to stay away from this pump, because the area of the rotating flywheel can be a dangerous playground.
===Construction, operations and maintenance===
Pump stand & flywheel are made of painted Mild Steel, the rising main consists of PVC-U pipes, the cylinder is made of glass fibre reinforced epoxy resin, plunger & the pump rods are of Stainless Steel and the valves of rubber. The pump is corrosion resistant.
This pump has a good “Community Management Potential”. Simple tools are needed to pull out the pumping element, including pump rod and foot valve. The seal-less piston means that no regular replacement of worn rubber seals is required.

Installation of the Afripump BluePump is easy and can be done by one technical person and one assistant. The Afripump BluePump comes standard with strong 70/80 m PVC rising mains and 9 mm 12mm full threaded stainless steel rods with threaded connections (Volanta technology). For the installations, no special tools or tripod is required, only keys nr 24 and 17 are needed to complete the installation. When the concrete base and drainage platform is ready, the metal stand is fixed on 4 6 anchor bolts and the pipes are glued and lowered into the borehole casing up to the desired depth. The handle is fitted to the base with 4 M16 bolts. The cilinder cylinder is lowered with the rods and the last rod is attached to the handle. The cover is put on and the pump is ready to use.
Based on the experience with of BluePumps over the Volanta handpumplast 5 years, the maintenance of the Afripump is limited to cleaning of the pump and platform, checking and occasionally tightening of some nuts & bolts, maybe applying paint from time to time, all other parts are maintenance free.
The Afripump is also 100 % BluePump can be considered as a VLOM pump(Village Level Operated & Maintained) because most of the few simple activities can be done by a local caretaker with an Area Mechanic local available materials and require no special tools, equipment or training.
===Costs===Studies show that families in rural communities will agree to pay 1 to 3 US$ per month for a reliable water supply, especially when there are no alternative nearby water souces availabalesources available. One handpump can serve 25 to 50 families that need 125 to 250 buckets of 20 litres/day, which equals 3 to 6 hours of pumping. This is enough to pay 25 to 50 US$ per month for the supervisor, the remaining revenues are sufficient to pay back the loan fully in 3 to 5 years.
