Standardised centrifugal pump
Standardised centrifugal monobloc electric pumps with coupling, designed for a wide range of applications, such as:
- Water supply.
- 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.
Rotation speed: 1450 - 2900 1/min.
Operating range: from 1 to 460 m3/h with head of up to 96 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
Flanging: PN 16 DIN 2533 - PN 10 DIN 2532 for DN 200
Protection class: IP55
Insulation class: F
Standard voltage: 230/400 V 50 Hz up to 2,2 kW included
400 V Δ 50 Hz above 2,2 kW
Installation: normally in horizontal or vertical position, provided that the motor is always above the pump.
Special executions on requests: pumps for liquids other than water.
Other voltages and/or frequencies.
CONSTRUCTION FEATURES OF THE PUMP
