Pump and valve gland packing

 

 

 

A packed gland seal or the conventional shaft seal is not often used due to its maintenance requirements. They require regular attention to adjust the amount of leakage, which is required to ensure proper lubrication of the gland packing. The life expectancy of a packed gland depends wholly on the liquid being pumped, with abrasive liquids reducing the life expectancy. Packed glands are recommended for aggressive liquids. Also when a packed gland fails it simply begins to leak more and can be tightened to reduce the leak with the pump remaining in service, where as a mechanical seal leaks dramatically when it fails hence the pump will have to be taken out of service. We are able to offer the very latest packing materials at very affordable prices. Marine Packing is a specialty of ours and all sizes from 1/8” (3mm) to 2” (50mm) are normally in stock. Equivalents to all major gland  packing manufacturers including beldam,eagle burgmann,Chesterton,James walker,aes,kinger latty,Unispec etc…

BJSEAL Injectable Packing
Injectable packing sealant compounds add to the choices for shaft sealing strategies for many industrial applications. When installed properly and maintained correctly this family of products can bring dramatic cost savings. BJSEAL now offers High Quality injectable Packing Sealant Compounds in grades to meet most industrial and water treatment facility needs.
•Quickly and easily replaces packing with virtually zero leakage.
•Reduces friction, runs cooler, and compensate for damaged shafts.
BJSEAL Packing is non-asbestos, universal pump and valve packing which has unlimited shelf life. It has a malleable (putty-like) consistency and is made from a carefully controlled blend of high-tech synthetic fibers and specially formulated lubricants and greases. BJSEAL Packing runs cooler than braided packing and never needs flush or cooling water. Braided packing is designed to leak and must leak to prevent burn-up. This is messy and expensive. By contrast BJSEAL Packing is designed not to leak and in most cases runs virtually leak free. This kind of product can be injected into the stuffing box using a hand operated hydraulic injectable packing gun. The product seals equally well in new applications and on worn sleeves or shafts.
Available in 5 Kg, 1 Kg and in 250g
