3D(4) SERIES

Standardised cast iron centrifugal pump with AISI 304 and AISI 316 steel impeller, axial suction and radial discharge with 2 or 4 poles motors. Available in three versions. Equipped with Back pull-out design that allows the motor, coupling, bracket and impeller to be removed without compromising the pump body or disassembling the piping. Many types of mechanical seals can be mounted on electric pumps to meet different requirements. Suitable for application in heating and air conditioning systems, water supply of civil, agricultural and industrial plants, pressurisation and fire-fighting. Read more

Standardised cast iron centrifugal pump with AISI 304 and AISI 316 steel impeller, axial suction and radial discharge with 2 or 4 poles motors. The 3D SERIES is equipped with Back pull-out design that allows the motor, coupling, bracket and impeller to be removed without compromising the pump body or disassembling the piping.
The many types of mechanical seal that can be mounted on the electric pumps allow the use of special materials. Therefore, they can adapt to different needs based, for example, on the type of liquid, temperature or other factors of use, covering, depending on the model, a wide range of temperatures.

The 3D SERIES is divided into three versions:
• 3D SERIES monoblock with extended shaft
• 3DS SERIES with rigid coupling and IEC Standard motor
• 3DP SERIES with elastic coupling and IEC Standard motor

For further technical information see the Databook

• Heating, ventilation and air-conditioning systems
• Water supply for civil, agricultural and industrial plants
• Pressurisation
• Firefighting systems
• Industrial liquid handling systems
• Irrigation for farms, sports facilities
• Washing systems
