Pump installation and applications
HF 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 large passages, make
them suitable for pumping even fairly dirty water.
HF pumps 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.
they can also be used for the transfer of diesel fuel.
Performance
HF pumps come in a wide and diverse range, making it easy to
select the model most suited to each requirement. special design
efforts were made to unify the entire HF series which is
distinctive for its:
Very high flow rates from low motor power, flat performance
curves.
Non-surging phenomena, even when pumping near minimum flow rates
Flat absorption curves at high delivery rates, to prevent motor
overloading even during prolonged use at high rates.
Good suction capabilities at both low and high delivery rates.
Curve tolerance according to iso 2548.
Structural characteristics
Cast iron pump body with uni iso 228/1 gas threaded suction and
delivery ports.
Open brass impeller.
Aisi 316 stainless steel motor shaft (aisi 416 up to 0.75 kw).
Ceramic and graphite mechanical seal
Motor: pumps are coupled directly to an asynchronous, high
efficiency pedrollo induction motor of suitable size, which is
quiet running, closed and externally ventilated, suitable for
continuous duty.
Insulation class f (b up to 0.75 kw and 1.1 kw three phase).
A thermal cutout relay (motor protector) is incorporated in
single phase motors.
Protection IP 44.
