Based on hundreds of tests, 300g is safe for lubrication of pipelines with a length of 50 meters and below, and the possibility of pump clogging is very small, while 220g or 240g pump lubrication is safe for pump pipes of about 50 meters. The probability of pumping is 85%. In order to allow concrete companies to use more lubricant, some manufacturers have reduced the packaging volume of their products, but the instructions still say it is effective for 50-meter pipes. This is an irresponsible approach. </p
