Standardised centrifugal pump
Standardised centrifugal single-stage pumps, designed for a wide range of applications, such as:
Hot water circulation for the heating system.
Circulation of cold water for air conditioning and refrigeration systems.
Transfer of liquids in agricultural, horticultural, and industrial environments.
Installation of pumping assemblies.
They can be coupled, using an elastic joint (standard or spacer), to a 2-pole or 4-pole electric motor, and installed on a formed metal sheet base in accordance with UNI EN 23661.
Rotation speed: 1450 - 2900 1/min.
from 1 to 470 m3/h with head up to 143 metres.
Pumped liquid: clean, free of solids and abrasives, non-viscous, nonaggressive, non-crystallised and chemically neutral, with properties similar to water.
Pumped liquid temperature range: from -10°C to +140°C.
Maximum ambient temperature: +40 °C.
Maximum operating pressure:
16 bar - 1600 kPa (for DN 200 max 10 bar).
Flanging: PN 16 DIN 2533
PN 10 DIN 2532 for DN 200
Installation: normally in the horizontal position.
Special executions on requests: pumps for liquids other than water.
Packing (also externally powered).
Other voltages and/or frequencies.
