Description

The PEDROLLO pumps of the CKR line have a double anti-blocking front seal and are recommended for pumping diesel/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.
