Filling method of fillers: Generally, the fillers are made of asbestos ropes in various specifications of different thickness and thickness. After soaking with butter, they are pressed into strips. The cross section is square, and graphite powder is coated on the outer surface. The thickness is cut into several sections and packed into the stuffing box.

Use a wrench to properly tighten the packing box gland (generally, the drip quantity is 60 drops/min).
