The IndiaMark III hand pumps are sturdy and robust pumps, with conventional action
lever, that can be installed in shallow to medium-deep wells. The pump is
designed for heavy-duty use and can serve village communities of up to 300
people. The configuration of this pump is very similar to the India Mark II,
except the down-hole components, which were slightly changed and modified to
make the hand pump more suited to village level operation and maintenance, with
simpler tools and lesser cost of maintenance. The most decisive modification
was the open top cylinder that allows for the removal of the plunger and foot
valve without the extraction of cylinder and rising main.
The pump
can be installed in a borehole or a dug well. Maximum recommended lift for the
India Mark III is 30 m. Apart from the standard 63.5 mm configuration, there
exists a version with Ø50 mm cylinder size for lifts of up to 50 m. The pump
head, handle, water tank, pump stand and pump rods are made of galvanized
steel, rising main of galvanized GI pipe, pump cylinder of cast iron / brass,
plunger and foot valve of brass. This pump is not corrosion resistant and this
limits its use to areas with suitable water conditions (pH value<6.5). It
delivers a maximum stroke length of 125mm and the water discharge ranges from
0.8 to 1.8 cubic meters per hour, depending on the head dimensions, which range
from 30m to 10m. The Cylinders are available in Ø50 mm and Ø62.5 mm. All the
above ground components of the pump can be locally manufactured, however, the
other components require a high degree of quality control check while
importing, to ensure a reliable operation. The cylinder can be installed and
repaired using simple tools, which allows for hassle free repairs by trained
locals, including women.
The India Mark III hand pumps manufactured
at Aakash International offer
optimum quality through excellent craftsmanship and stringent adherence to
industry standards. The raw materials required to build these products are
acquired from trusted industry vendors, and are integrated with advanced
working mechanisms. Apart from that, strict quality control methods are
followed during the manufacturing of these products, which ensures that only
the best quality reaches the customers, at modest and affordable prices.
Additionally, the pump is available in two variations- 50mm OTC and 65mm OTC,
which differ in the dimensions of the riser pipes. Both these variations can be
installed in a borehole of up to 45m. Also,
comprehensive and detailed user manuals along
with tool kits are provided along with the product to ensure hassle free and
easy installation, besides smooth repairs.
