PUMP INSTALLATION AND APPLICATIONS
MHF
pumps are specifically designed for domestic,agricultural and
industrial use.Their performance levels,mechanical design and
structural materials are explicitly selected for these
uses.The shapes of their volutes and impellers,with ample
passages,make them suitable for pumping even fairly dirty
water.They can achieve high delivery rates under continuous or
heavy duty, making them advantageous for rain and gravity
irrigation, for pumping water from lakes, rivers, wells, and
for a wide variety of industrial uses where high delivery
rates must be achieved at low to average heads.
The pumps
should be installed in a covered area,protected against the
weather.
PERFORMANCE
MHF pumps come in a wide
and well-diversified range.
Characteristic curves for the
different models are distributed in a rational and
complementary manner,making it easy to select the model most
suited to each specific user requirement.
Special design
efforts were made to unify the entire MHF series,which is
distinctive for its:
¡ù especially ample characteristic
curves;
¡ù no surging phenomena even when pumping near
minimum forecast delivery rates;
¡ù performance
cheracterized by high absolute values over the majority of the
characteristic curve;
¡ù flat absorption curves at high
delivery rates,to prevent motor overloading even during
prolonged use;
¡ù good suction capacities at both low and
high delivery rates.
STRUCTURAL CHARACTERISTICS
¡ù Cast iron pump body
¡ù
brass impeller with centrifugal radial flow type
¡ù
stainless steel shaft
¡ù with thermal overload protector in
single phase motor, all three phase motors require an adequate
external motor protector,
and connections are to be
according to current standards
¡ù stainless steel mechanical
seal (graphite to SiC)
¡ù protection IP 44.
¡ù NSK bearing
or local bearing
