Features
Available with brass impeller
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 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.
For further technical information see the Databook
• Pressurisation of domestic installations
• Small-scale irrigation
• Washing systems and vehicle washing
• Handling of non-aggressive liquids for civil and industrial use
