LIBRA WINDPUMS
FOR DRINKIN, GARDENING
AND FARMING WATER
DESIGN APPROVED BY
GOVT. BALOUCHISTAN
Design for low cast and
high reliability. Very smile but elegant design. Uses a simple crank
and rocker arrangement, with specially developed rotor. Lubrication
needs only once a year, because for the continually moving joints,
obliging ball baring units are used.
The pump itself consists
of a simple cylinder incorporating a non-return valve at the bottom
and another in the piston.
Libra wind pumps protect
themes from damage in very strong winds, by turning the rotor edge on
the wind.
