Description
The Pedrollo NGA 1B centrifugal electric pump is recommended for use in the agricultural, domestic and industrial sectors.
Pedrollo designed this pump with an open impeller, allowing it to pump relatively heavy liquids without clogging the impeller. It allows solids up to 12 millimeters in diameter to pass through.
The NGA 1B, due to its open impeller design, is suitable for applications such as transfers from canals, rivers, tanks and basins.
It has a flow rate ranging from 40 to 350 liters and a reach of 5 to 18 meters. The pump body supports a maximum working pressure of 6 bar .
