According to hundreds of tests, 300g is safe for lubrication of pipelines with a length of 50 meters and below. The possibility of clogging the pump is very small, while 220g or 240g of lubrication is safe. The possibility of the pump agent blocking the pump pipe of about 50 meters 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
