Li-Tak Machinery

APPLICATION

For water supply from tanks, basins or tubs and from open wells
(large wells) or from 6” wells for residential, civil or agricultural use
and for pressurizing water in general.

USES
Supply of clean water and non-aggressive chemical liquids. OP pumps
are suitable for domestic use, for water automatic distribution by
using small-middle pressuretanks, for gardening, irrigation, water
supply from wells. Furthermore, thanks to the the high head, OP
pumps can be used as pilot pump for pressurization units.
