The India Mark 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 the
cylinder and rising main.
The
pump can be installed in a borehole or a dug well. Maximum recommended a
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

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
toolkits are provided along with the product to ensure hassle-free and
easy installation, besides smooth repairs.
