Section size (mm) Length to weight ratio (meters / kg) Installation precautions
3.00X3.00 65.36 1. Selection of packing size: measure the diameter of the shaft and the inner diameter of the packing chamber. The two data are subtracted and divided by two. The result is the required size of the packing. In general, the packing size is “small and not big”;
2. When using the packing, first cut it into a single ring with a knife: flat or beveled;
3. Allowing the pump to leak within an hour of turning it on will cause the packing to be in good working condition, then gradually press the cover until the leak reaches the allowable range. It is generally not recommended that the pump be sealed to a leak-free condition.
