Description
Overview:
The new In-line close-coupled centrifugal pump has been designed to improved performance and energy saving.
The pumps are equipped with cast iron casing and available with 2 or 4 pole motors and with integrated E-SPD+ frequency converter (3E-K).
Used in handling of liquids in circulation, heating and air conditioning systems in civil and industrial environments.
Features:
• Robust design
• High efficiency
• Easy maintenanceCONFIGURATIONS
1. 3E – Extended shaft
2. 3ES – Stub shaft
3. 3E-K – Extended shaft with VFD3E-3ES
The new in-line close-coupled centrifugal pump is characterized by suction and discharge connections in line with the piping.
The design of the extended shaft version (3E) is made of an impeller mounted directly on the end of the motor shaft, and a pump casing that bolts directly to the face of the motor.
The design of the stub shaft version (3ES) is characterized by a motor shaft and a pump shaft rigidly connected in a pump casing.
3E electric pumps are versatile and silent, with a robust design and ease of maintenance thanks to back pull – out design to reduce downtime.
They are equipped with IE3 motors as standard, IE4 and IE5 premium efficiency motors are available as option for the stub shaft version.3E-K
The new In-line close-coupled centrifugal pump complete with integrated E-SPD+ frequency converter.
The E-SPD+ is the new air cooled inverter, capable of varying the speed continuously and operating on any working point, consequently optimizing performances and consumption according to the system’s requirements.
Extended output range with respect to the E-SPD and designed to include new HVAC functionalities; differential pressure and temperature control, 0-10V analog input, Modbus for external communication.
The 3E-K pumps are available up to 11kW and can be used in handling of liquids in circulation, heating and air conditioning systems in civil and industrial environments.For further technical information see the Databook.
• Handling of liquids in civil and industrial circulation, heating and air conditioning systems
