The XL’s are rugged and very accurate single-block positive return hydraulic diaphragm pumps suitable for high demanding 24/7 industrial applications.
Built in full compliance with API675 and ATEX 2014/34/UE standards, these pumps house a relief valve, an air purge valve, and a mechanically actuated self-replenishing hydraulic system.
These features combined protect the pump and the whole dosing system from damages due to overpressures, while granting a proper chemical dosing under any circumstances.
