2. TECHNICAL SPECIFICATIONS
Multistage centrifugal pumps can be of the following series:
– HP HPM and HV HVM for pressures up to 64 bar.
– HPR for pressures up to 100 bar.
The horizontal pumps series HP, HPM, HPR (fig.8) are usually coupled to
the motor through an elastic coupling, and mounted on common
base-frame.
The vertical pumps series HV, HVM are instead driven by flanged motors
(fig.9)
These pumps have been designed and manufactured for the following use:
• industrial water works and water supply systems
• irrigation and reclamation
• in line pressure boost systems
• steam boiler feed
• condensate conveyors
• fire fighting systems
• water treatments plants
pumped fluids: fresh water (standard execution), seawater, conden-
sate, chemical and petrochemical substances (special execution on
request).
The range of pumps can be divided in (fig.10):
• centrifugal pumps type HP,HPM
for pressures up to 64 bar and capacity from 3-900 m≥/h.
• centrifugal pumps type HPR
for pressures up to 100 Bar and capacity from 3-900 m≥/h.
• centrifugal vertical pumps type typo HV,HVM
for pressures up to 64 bar and capacity from 3-900 m≥/h.
