About Pump 3D4-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.
Features
- Sturdy construction
- High efficiency
- Impeller in stainless steel
description Pump 3D4-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. 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

Back pull out design and shielded bearings
This configuration ensures disassembly and inspection of the pump without having to remove it from the system piping. Furthermore, the use of shielded bearings eliminates the need to add or replace lubricating oil.
This solution facilitates and speeds up maintenance
Bare axis pump and electric pump
GS models are available both in the bare axis version and in the electric pump version, with motor powers up to 355 kW. The available motors are 2 or 4 poles, 50 Hz, IE3 efficiency, coupled with inverter
Sealing options
The seal is available in two different versions:
• SiC/Carbon/EPDM mechanics for liquid temperature up to 120°C
• A packing that guarantees resistance to wear and ensures that the tightness of the entire system is monitored visually
