PUMPS INSTALLATION AND APPLICATIONS
MGA 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.
MGA 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 MGA range,to typical requirements for pumps having to perform the functions described above.
The result is a series of pumps characterized by:
¡ù especially wide and flat characteristic curves,making it possible to handle large quantities of water;
¡ù efficiencies with high absolute values over much of the characteristic curve(efficiency curves that tend to be flat);
¡ù flat adsorption curves at high delivery rates,to prevent motor overloading even during prolonged use at high rates.

STRUCTURAL CHARACTERISTICS
¡ù cast iron pump body
¡ù stainless steel pump body cover
¡ù stainless steel mechanical seal(graphite to ceramic)
¡ù brass impeller with open type
¡ù Hi-Cr plated 45# steel shaft
¡ù protection IP44
¡ù with thermal overload protector in single phase motor
¡ù NSK bearing or local bearing

WARRANTY:1 YEAR(according to our general sales conditions)
