The BluePump is more easy to install than any other handpump. BluePump dealers provide training on demand as well as a quick technical update for local pump mecanics that are already familiar with handpump installtion.
Therefore FairWater developed the Bottom Support option. This option is strongly recommended in case the cylinder is situated below 40m. We have over 8 years experience with Bottom Support installation with very good resuts all over Africa.
The BluePump can therefore be installed in two ways:
In case of shallow static water tables (not deeper as 25 to 30m.) the cylinder can be installed in PVC rising mains that are “hanging” at a flange-socket inside the base plate.
This procedure is the same as for the hanging pipes, only the beginning and the end are different.
Rehabilitation of abandoned handpumps with the BluePump
In Africa many handpumps are not functional. However, the (expensive) borehole is still usable. Therefore it is cost-effective to rehabilitate abandoned handpumps with the durable BluePump, which fits directly on the 4 bolts of the pedestal of old India or Afridev handpump. Rehabilitation is easy and fast.
Please note that old boreholes may have silt accumulated on the bottom and the PVC pipes may slowly sink 10 to 20 cm. in the first months. To compensate for this, the rods as well as the rising main need to be extended with the same length.
