PUMPS INSTALLATION AND APPLICATIONS

GA pumps are recommended for pumping water and fluids which are not chemically aggressive to the pump components.The open impeller design enables fairly large amounts of impurities to be pumped without danger of clogging.

GA pumps are very dependable,simple to use,and virtually maintenance-free.They suit a wide range of industrial applications watering gardens and transferring water from canals,rivers,tanks,tubs,etc.

These pumps should be installed in a covered area,protected against the weather.

 

PERFORMANCE

Special attention was given,when designing performance levels for the GA range,to typical requirements for pumps having to perform the functions described above.

The result is a series of pumps characterized by:

especially wide and flat characteristic curves,making it possible to handle large quantities of water.efficiencies with high absolute values over much of the characteristic curve(efficiency curves that tend to be flat)flat adsorption curves at hight delivery rates,to prevent motor overloading even during prolonged use at high rates.
