Injectable Packing
Injectable packing is not a new concept, however Utex has developed a new
means of containment that has revolutionized injectable packing. This
new means of containment (patent pending) enables injectable packing to
perform even better than before in most services, especially where abrasive
particles are present in the pumpage.
Injectable Packing
Utex Industries manufacturesseveral styles of UPAK to fit
most packed box applications
Injectable Packing
Although UPAK is available in bulk form, pre-packaged “sticks” of UPAK make loading the hydraulic injection gun simple.
Injectable Packing
The “Giant Button Head Fitting” and companion quick coupler are designed especially for the injection of highly viscous materials.
Injectable Packing
Pictured here with optional ball valve, the “Giant Button Head Fitting” contains a ball check, eliminating the need for an additional valve on most applications.
Typical Installation
UPAK will run leak free in most common applications for extended periods of time.
When leakage does occur, no gland adjustmentis necessary. Simply inject more UPAK throughthe port until leakage subsides. This can be done without stopping the pump.
Injectable Packing
The “ASF” ring is a molded seal ring similar to a “Vee” or “Chevron” type ring. The difference is that it is flat backed and doesn’t require a top adapter. These rings can be molded from a myriad of different compounds and can be of either homogeneous or composite construction.
In order to facilitate easy installation, we have devised a means of cutting the molded rings in an interlocking fashion that keeps the joint from separating during installation or during equipment operation. The result is superior anti-extrusion of the UPAK material and/or limited contamination of the UPAK from process liquid.
The bottom ring is oriented toward the UPAK on most services but when the process contains abrasives, the bottom ring can be rotated to keep abrasives out of the UPAK.
Installation with ASF Rings
Leakage can be controlled by adding UPAK without stopping the pump, thus preventing costly downtime.
Installation with ASF Rings
Compression Packing vs. Injectable Packing
Compression Packing:• Requires break-in time• Must leak to lubricate• Must be adjusted regularly• Shutdown required to adjust• Causes severe shaft damage• Cannot seal on damaged shaft• Frequently requires replacement
Injectable Packing:• Requires no break-in time• Runs leak free• Easy & infrequent adjustment• Shutdown not required to adjust• Causes no shaft damage• Can seal on damaged shaft• Infrequently requires replacement
Utex Industries has several styles of UPAK available to fit most any
application. Contact you Utex Representative or an Authorized
Utex Distributor near you to discuss your specific applications.
