CDU/2CDU Stainless-Steel Centrifugal Pump
The EBARA CDU and 2CDU Series are high-performance stainless steel centrifugal pumps designed for clean water transfer, pressure boosting, and general industrial applications. These close-coupled, compact pumps deliver dependable operation, energy efficiency, and long service life while minimizing space and maintenance requirements.
Constructed from corrosion-resistant stainless steel, the CDU and 2CDU are ideal for environments demanding hygiene, durability, and resistance to aggressive media — from water treatment and reverse osmosis to irrigation and ultrapure water systems.
PRINCIPLE OF OPERATION
The CDU and 2CDU are centrifugal pumps that use an impeller to impart energy to the liquid, converting rotational energy from the motor into kinetic and pressure energy.
Both models feature a close-coupled motor configuration, meaning the impeller is mounted directly on the motor shaft, reducing alignment issues, vibration, and installation footprint.
The single-stage CDU is ideal for standard flow and head applications, while the two-stage 2CDU provides higher head performance for systems requiring additional pressure.
