Single impeller cast iron centrifugal electric pump CMC-CMR

Single-impeller centrifugal pump with cast iron body, available in different models: CMA – CMB – CMC – CMD. Depending on the model, the impellers, shafts and motor mount can be made of different materials (see technical data table).

Single-impeller centrifugal pump with cast iron body, available in different models: CMA – CMB – CMC – CMD.
Depending on the model, the impellers, shafts and motor mount can be made of different materials (see technical data table). Their compact size makes CMA-B-C-D centrifugal electric pumps easy to install even when spaces are narrow or difficult to reach.
Their sturdy and reliable structure allows for high performance in all water handling applications.
