__NOTOC__ <small-title />

====The Volanta pump====

====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===

====BluePump====

Installation of the BluePump is easy and can be done by one technical person and one assistant. The BluePump comes standard with strong 70/80 m PVC rising mains and 12mm full threaded stainless steel rods. For the installations, no special tools or tripod is required. When the concrete base and drainage platform is ready, the metal stand is fixed on 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 of BluePumps over the last 5 years, maintenance is limited to checking and occasionally tightening of some nuts & bolts, maybe applying paint from time to time, all other parts are maintenance free.
