The Calpeda N80/160 is typically a cast iron, bare-shaft centrifugal pump. This means it's designed to efficiently move liquids by converting rotational energy into hydraulic energy. Key components usually include:   

Pump body: Made of cast iron for durability and corrosion resistance.   

Impeller: The rotating component that lifts the liquid.

Shaft: Transmits power from the motor to the impeller.

Inlet and outlet: Connections for fluid entry and exit, often with a size of 100/80mm
