CKm 50 - 0.50 HP single-phase self-priming liquid ring electric pump
Flow rate up to 40 l/min (2.4 m³/h). Head up to 35 m. Motor 0.37 Kw (0.50 HP).




They 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.
Installation must be carried out indoors or in any case protected from the elements.
