Ebara CDA Series Twin Impeller High Performance Cast Iron Centrifugal Pumps
Ebara CDA Twin Impeller Cast Iron Single Phase Centrifugal Pumps
| DOWNLOAD PRODUCT BROCHURE |
The Ebara CDA Twin Impeller Centrifugal Pumps are compact yet powerful cast iron pumps designed to deliver high performance in a small footprint. Featuring a twin impeller configuration, the CDA series offers increased pressure output, making them ideal for domestic water boosting, small-scale irrigation, washing systems, and handling clean non-aggressive liquids in both civil and industrial applications. With robust materials and a proven design, the CDA series is a reliable choice for a range of medium-duty pumping tasks.
The pump body is constructed from cast iron for strength and durability. Lower power models (CDA 0.75 and CDA 1.00) feature glass-fiber-reinforced technopolymer impellers and aluminium motor support, while higher capacity models incorporate brass impellers and cast iron motor supports for improved resilience under heavier loads. Suitable for liquid temperatures up to 90°C (model dependent) and pressures up to 10 bar, the CDA range is a versatile solution for high-head, clean water applications.
