A Deep Well Hand Pump
is used when the static water level (distance between the top of the
ground and top of the water level) is more than 20 meters. In most
cases, the pump cylinder is installed at least 20 meters below the
static water level and connects to the wellhead through a series of PVC
pipes and stainless steel lift rods. Since these pumps draw water from
deeper than usual levels, it is necessary that they are sturdy and
strongly built.
The
deep well hand pump can be installed in bore wells of a diameter of
minimum 125mm and the internal diameter of the underground cylinder
ranges from 60-65mm. the stroke length ranges from 120-130mm. these hand
pumps give a water discharge of 12-15 liters per minute of 40 strokes,
and an average of 900-960 liters per hour. The maximum depth of
operation of these hand pumps is 30 meters. These pumps are self-priming
and do not require routine maintenance. Also, they are available in
different grades and dimensions, which can be customized as per the
client requires. This pump has excellent “community management
potential” and can be easily installed and repaired by a village
caretaker or women, making it popular with small communities. The above
ground parts of the pump can be locally manufactured, but the rest of
the components require a high degree of manufacturing quality, which is
not available around the globe. So in some countries, these components
need to be imported. However, imported components require strict quality
control and check to increase the lifetime of the hand pump, and
considerably reduce wear and tear of parts and disuse due to corrosion.
