Description
The HF 20B centrifugal electric pump from Pedrollo 's HF series is efficient and offers high performance in terms of head.
Pedrollo has made the pump with materials such as cast iron and 2 types of stainless steel, AISI 304 and 431, for a solid and resistant result.
Suitable for those who perform long work sessions. High flow rates are preferred, while the prevalence values are lacking.
The HF 20B is recommended for use in agriculture and industry. It is suitable for surface and sprinkler irrigation, and for drawing water from lakes, rivers, and wells.
