The gear pump continuously supplies lubricant to re-lubrication metering devices via the main line network when the pump is in operation. When the metering chambers of the metering devices are full, excess lubricant flows back into the reservoir via the safety valve. At the end of the pump running time, the pressure relief valve opens.
The pressure in the main line drops to a residual pressure of 0,2 to 1,0 bar (2.9 to 14.5 psi), allowing the spring-loaded pistons of the metering devices to deliver lubricant from the metering chambers to the lubrication points.
