Ebara CM Series Single Impeller Cast Iron Centrifugal Pumps
Ebara CM Series Single Impeller Cast Iron High Flow Centrifugal Pumps
| DOWNLOAD PRODUCT BROCHURE |
The Ebara CMA and CMB Series are compact, high-performance single-impeller centrifugal pumps designed for reliability in a wide range of water handling applications. With a rugged cast iron body and impellers available in PPE+PS, brass, or cast iron (depending on the model), these pumps are engineered to deliver long-lasting service even in demanding conditions.
Ideal for pressurisation of domestic water systems, small-scale irrigation, and civil or industrial liquid transfer, the CMA/CMB pumps are easy to install in tight or hard-to-access spaces. Available in single-phase or three-phase configurations, these pumps support flows from 1.2 to 60.5 m³/h and heads up to 57.0 m, making them versatile for everything from vehicle wash systems to non-aggressive liquid handling.
The CMA 1.00M features 25mm suction and discharge ports, while the CMB series offers larger configurations with 50mm suction and 32mm discharge. The durable design includes ceramic/carbon/NBR mechanical seals, IP44-rated motors, and operating temperatures up to 90°C on most models.
