The EUR 1 pneumatic pump is a single-acting pump suitable for all types of applications. The maximum amount of grease supplied during every pumping cycle is 30 cm³ (an amount that is approximately sufficient for 100 lubrication nozzles). The pump supplies, during each cycle, the amount of grease required by the meters, thus preventing the output of additional amounts both while the cycle is running and in idle mode. The pump does not require specific calibration and can be used to supply a number of meters ranging from 1 to 100. A low grease level and system faults are signaled by the lighting of the yellow LED on the timer, which is in turn controlled by the piston limit switch contact placed inside the pump..
