I pumps

Use

Nautical Agriculture Transport

The best solution for the suction and transfer of liquids, thanks to the strong self-priming capacity, the ability to run even with discontinuous presence of the liquid in suction and the reversibility of the flow. The I series is made of CB754S brass with a stainless steel shaft. This version with support and pulley allows easy coupling with any motor. For each application, it is necessary to check the suitability and choose appropriate gaskets.
