Technical Data
 

The BluePump handpump is designed to pump day and night in the harshest conditions, and that's what it does, day in and day out...  it's a most rock-solid, reliable, manually operated water pump available for rural water projects in Africa.

All components are made from high-quality materials, while the technology behind the BluePump concept is simple and reliable. Therefore the BluePump is cheaper to operate & more easy to maintain than any other handpump on the market.

The BluePump can pump up to 100m deep
Due to it's special designed riser pipe system, with an extractable (stainless) steel cylinder and flexible Bottom Support pipes, the standard BluePump assembly can easily pump water from 100m deep. That means one type of pump for all depth. This is also convenient for the spare parts; no special spares are required in those zones with deep groundwater.

Maintenance free pump system
The revolutionary stainless steel pump system of the BluePump is simple, reliable and basically maintenance free. This means that the pump will not suddenly stop due to technical problems or wear and tear on the piston or cylinder.  

One of the reasons for that is the fact that the BluePump piston has NO rubber seal. Such seals in other pumps are the main cause of their many breakdowns. The only basic maintenance the BluePump requires is checking nuts and bolts on the pump stand.

Having said that, it is obvious that "maintenance free" does not guarantee that the BluePump will never ever break down of will never have a problem. Murphy's law also exists in Africa.

Also, in any mechanic device, moving parts may wear out with time. However, the BluePump is designed in such a way, that all parts last 10 to over 100 times longer compared to other pumps, which makes a huge difference in water security and maintenance costs.

For instance the centralizers: In deep boreholes, especially in case the borehole is not vertical, the lower centralizers can wear out with time. However, they are double on each rod and can be turned around for a new life and switched with the upper centralizers. The BluePump is, therefore, the most sustainable and low-cost maintenance solution for rural water supply.

The BluePump is mounted on a solid concrete pedestal with 6 extra long anchor bolts. In case of deep installations, the handle can have an additional counterweight to make pumping lighter. To avoid stress on the PVC pipes, the BluePump rising main pipes can be extended with a free moving bottom support system (BPS).

Installation is extremely easy and can be done without specific tools by 2 persons. First, the PVC pipes are installed with a rope, and after that, the cylinder is lowered with the rods. The position of the cylinder must be at least 10m below the static water level. For inspection, the cylinder can always easily be taken out while the PVC pipes stay in the borehole.
