Description
The Pedrollo electric pump from the CKRm 90 line is built with a double anti-blocking front seal and is recommended for pumping diesel or naphtha, clean water without abrasive particles and liquids that are chemically non-aggressive for the materials from which the pump is made.
Thanks to their specific operating principle, they are an easy solution in all cases where a compact self-priming pump is required or the liquid flow is poor or irregular or mixed with air.
