The combination of unmatched metering accuracy, robustness and reduced footprint make the OBL L X9 hydraulic double-diaphragm pump the ideal solution for a wide spectrum of industrial dosing processes. The positive return mechanism (lost motion) grants a high reliability and durability, while the built-in safety and purge valve allow for a constant suction lift and chemical dosing under any working condition. Allowing for a multi-head configuration to match any dosing need, the OBL L X9 pumps include a diaphragm rupture detection system, and comply in full with API675 and ATEX 2014/34/UE standards.
