The BluePump can be installed (Click here) in a few hours by two persons up to 100m deep, without the need for a tripod or other special complicated tools. BluePump dealers provide training on-demand as well as a quick update for local pump mechanics that are already familiar with the installation of another type of handpump, such as Afridev and the India MK2.

Basically, because the BluePump works with the simple system of a piston that moves up and down in a cylinder, the installation procedure is the same as similar pumps. However, there is one major difference in the case of a so-called "Deep Installation". In that case, the pipes of the pump are not "hanging" on the T-piece, but the pipes continue until the bottom of the borehole. This is called the "Bottom Support" (BS) System, a breakthrough innovative idea to improve the reliability of deep handpumps, developed by Paul van Beers around the year 2000.
Click here for the video about installing a BluePump in Turkana, Northern Keny, using the installation rope to easily let the pipes go down into the deep borehole, here about 95 m. with an installation of the pump cylinder at 65m. deep.
What is the Bottom Support System (BSS)?
The riser pipes of the BluePump are made of strong BOODE PVC pipes with glued connections. PVC pipes are perfect for all types of groundwater, they are relatively light and easy to work with. However, when many PVC pipes are suspended in a borehole, due to the total weight they will stretch up and down during pumping.
With time this can cause small cracks and leaks. To avoid such repairs, we have developed the "Bottom Support System (BSS) to support the Rising Main pipes with additional pipes below. These additional pipes are the same pipes as the Rising Main, and can be either open inside, or made floating by using closed sockets. Floating pipes make deep installation easier and do not press too much on the bottom of the borehole.
Over 1.000 BluePumps are installed with the BSS, it's now a proven technology that makes installation easy and avoids PVC pipes to break.
The BluePump can, therefore, be installed in two ways:
1. Standard installation; with PVC pipes hanging on the T-piece.
2. Bottom Support installation; with PVC pipes all the way to the bottom.
In either way, the installation of the steel Blue box (35) parts and the handle (47) is the same.
1. Hanging pipes installation; cylinder installed at < 50m.
In case of shallow static water tables (less than 40m deep), the installation of the conical seat the PVC rising mains are “hanging” at a flange-socket (6).
2. Bottom Support Installation >50m.
The Bottom Support (BS) is needed in case the cylinder is installed below 50m. The advantage of the BS installation is that all of the PVC pipes are resting on the floor of the borehole, so there is no heavyweight hanging on the T-piece. Generally, BS are found in boreholes with a static water level of about 60 to 70m. and with a Bottom Support of 10 to 20 PVC pipes or 20 to 40m. Please note that these BS pipes are the same pipes as we use for the rising main.
