PEDROLLO HF

The PEDROLLO HF Series are non-self-priming pumps with close-coupled motors for high flow rate applications.

They have sufficient passageways in the volute and impeller to enable the pumping of water with a light silt load specifically made for heavy-duty industrial and agricultural use. Because of their back pullout design, the pumps can be disassembled without removing the pump casing from the pipework.
