Single Spring Seal vs. Component Seal vs. Cartridge Seal GOOD Single Spring Seal BETTER Component Seal BEST Cartridge Seal Positive Low initial cost Good alternative to packing Positive Inexpensive initial cost Multiple springs for even loading on seal faces Springs outside of process fluid [...]
MECHANICAL SEALS OR PACKING? There is an upside to change from packing to mechanical seals, however not all conditions favor seals, so a good general knowledge about sealing systems is important in the decision process. In order to understand why pumps need to be sealed, we need to go back to some pumping basics and [...]
What Is The Difference Between Single and Dual Mechanical Seals? Single Cartridge Seal - AST What Is A Single Mechanical Seal? A single mechanical seal consists of two very flat seal faces that are forced together by a spring and slide against one another. Between these two faces is a thin fluid film [...]
Summer Safety Tips When temperatures get this hot in Boise and surrounding Treasure Valley, it's always a good idea to review some summer safety precautions. Wear clothes that are suitable for your work. Working without a shirt on can be dangerous. For work involving any grinding, welding, machining, or other similar tasks, we recommend wearing [...]
If rolling bearings are to operate reliably and realize their full service life, the must be adequately lubricated. The function of the lubricant is to form a protective oil file that separates the bearing components and prevent metal to metal contact. The lubricant also protects the bearing and related components against corrosion. When grease is [...]

The History of Electric Motors In the 1830's, Michael Faraday made a discovery that has made work easier for all of us. While experimenting with magnets he found that moving a wire through a magnetic field would produce an electric current. This experiment is important because it led to the discovery of the operating principles [...]
