__NOTOC__ <small-title />

The Afripump, also called the Blue pump, is an upgrade from the Volanta pump. It no longer has a flywheel, is cheaper, and is said to be more reliable. The Afripump is the upgrade to communities with existing Volanta pumps. Below is the story and details of how the Afripump came to be more useful and some information about the Volanta pump, for those still existing in use.

====First came the The Volanta pump====The Volanta Pump, created DGIS in co-operation with by Jansen Venneboer B.V., is a reciprocating pump driven by a large flywheel for medium to very deep wells. It uses a retractable cylinder and a seal-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 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 adjustable to reduce the effort needed at deep installations.

It is designed for heavy-duty use and the maximum recommended lift installation depth is 70 50 m.

The Volanta Pump is not in the public domain and information can be asked from the manufacturer. The Volanta Pump is fully corrosion resistant. It is rather difficult to install and it needs extensive masonry work. Maintenance Regular maintenance is easy so that communities can care for the pumps.

====The BluePump====

The BluePump was designed by the FairWater Foundation with the imput input of many NGOs in Africa. A major contribution was given by Oxfam Kenya, that has tested the early models of the BluePump in it's handpump rehabilitation project in Turkana, Northern Kenya. After several modifications to addapt adapt the BluePump for depth up to 100m deep, the BluePump is now considered by most international NGOs as the most reliable handpump, especially suited for deep boreholes. One of the special features of the BluePumps is that the PVC rising main can be 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 the pumping action.

In many parts of Africa the BluePump is 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 India Mark pumps.

The key success of the BluePump is its reliablityreliability. This is due to it's simple and strong design and the fact that it basically needs no spare parts for many years. This means that communities have water for a very long time, at a very low price.

For the Operation & Maintemamce Maintenance (O&M) asepects aspects of the BluePump FairWater recommends a regional approach, in which an Area Mechanic is involved already in the installation phase of the BluePump and gives additional back-up technical support in case needed. Training of the Area Mechanics and spare-parts supply is available with country dealers, whos who also have BluePumps in stock.

More info about the BluePump can be obtained by FairWater.

====Why the BluePump is more reliable====

Most other handpumps fail due to many technical reasons: The most common propblem problem is worn out seals and broken pipes. Other problems are leaking footvalves 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 maintence 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 footvalve foot valve has 2 stainess stainless steel balls fpor 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 greated great depth.

===Suitable conditions===

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.
