EBARA 3D(4) Series EN 733 End-Suction Centrifugal Pump
The EBARA 3D(4) series is a standardised (EN 733) cast iron centrifugal pump with an AISI 304 or AISI 316 stainless steel impeller, axial suction and radial discharge, driven by 2 or 4 pole motors.
Thanks to the back pull-out design, the motor, coupling, bracket and impeller can be removed without disturbing the pump body or disconnecting the piping. A wide choice of mechanical seals makes the pump suitable for different liquids and temperatures.
Main features
- 3D – monobloc version with extended shaft
- 3DS – with rigid coupling and IEC standard motor
- 3DP – with flexible coupling and IEC standard motor
- Back pull-out design for easy maintenance
- Mechanical seals in several material combinations (H, HS, HW, HSW, E)
Applications
- Heating, ventilation and air-conditioning systems
- Water supply for civil, agricultural and industrial plants
- Pressure boosting
- Firefighting systems
- Industrial liquid handling
- Irrigation of farms and sports facilities
- Washing systems
