CA 2274601

An adjustable packing gland assembly mounted for adjustable engagement with packing in fluid pumping apparatus for sealing against fluid leakage about reciprocating plungers and like pumping elements also stabilizes the pumping element. A packing gland housing is formed in the pump and spaced packing gland shoulder bolts bottom out on that housing. A packing gland is disposed in the packing gland housing and is slidably mounted on the spaced packing gland shoulder bolts, each of the shoulder bolts having adjusting nuts and pipe sleeves disposed for precision adjustment of the packing gland. Bearing against the plunger on either side of the packing are guiding elements made of a low wear material which possesses lubricity as against the plunger. The upper guide may be integrally formed with the gland. An eccentric liner is made of a similar material as the guides, rendering it a low wear item in need of little or no lubrication.
