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
