What is a packing puller?
A packing puller, hook or pick is a device that looks like a corkscrew on the end of a rigid or flexible shaft. They are made of different sizes to fit between the shaft and casing of a stuffing box of various size pumps and valves. The screw is twisted into the soft packing and then it is pulled out of the stuffing box. A packing pick is one of three tools that look like dental picks for removing leftover scraps of packing or for getting into tiny valve stuffing boxes.

Is pump discharge pressure is equal to stuffing box pressure?
No, pump discharge pressure is not necessarily equal to stuffing box pressure. The discharge pressure refers to the pressure at the outlet of the pump, while stuffing box pressure is the pressure within the stuffing box where the pump shaft passes through. The stuffing box is designed to prevent leakage and can experience different pressure levels due to factors like friction and the sealing material used. Typically, the stuffing box pressure is lower than the discharge pressure, especially if the packing is providing effective sealing.

Why stuffing box required?
A stuffing box is required to prevent leakage in rotating or reciprocating equipment, such as pumps and valves. It provides a sealing mechanism around a shaft, using packing material to contain fluids while allowing for some movement. This helps maintain pressure and prevents contamination, ensuring efficient operation and extending the equipment's lifespan. Proper maintenance of the stuffing box is essential to avoid excessive wear and leakage.
How do boats with holes in their hulls for the propellar keep out water?
The propeller is at the end of a shaft. The shaft passes through a fitting called a stuffing box. The stuffing box contains a material like cotton or waxed twine that wraps around the shaft. There are two or more bolts that hold the stuffing box together and by tightening or loosening the bolts you can squeeze or release the stuffing material to the shaft. Ideally you tighten the bolts to the point that water just drips in. This allows the shaft to spin freely. It is lubricated by the water. If you tighten the box too much then you can score the shaft. The water that drips in is usually pumped out by a bilge pump.
