It's not uncommon for many of our customers to have a backup electric motor in storage to maintain productivity in the event of a motor failure. However, if the electric motor is stored properly, it may not be reliable when its needed. Here are few tips that might help: Store It Indoors. It's not [...]
O-Ring Material Characteristics EPR/EPDM - Ethylenne Propylene Excellent compression set and resistance, limited temperature range. USE Water/steam, acetone, diluted acids and caustics, ketones. AVOID Mineral Oil, solvents, aromatic HC FKM - Fluoroelastomer/fluorocarbon (Viton®) Excellent high-temperature resistance with good chemical resistance and compression set properties. [...]
Piping Plan 52 Set Up (Graphics Courtesy of Hydraulic Institute, www.pumps.org) Dual mechanical seal with reservoirs can be used with good effect in implementing Plan 52 to provide buffer fluid resulting in no direct leakage of process fluid to the atmosphere. Circulation between the reservoir and outer seal is maintained by tangential flow porting [...]
Best Efficiency Point (B.E.P) We hear a lot about operating pumps at the best efficiency point from pump manufacturers and engineers. It is noted on most pump curve drawings and is common terminology implementing or troubleshooting pump installations. The Best Efficiency Point (B.E.P.) is described as the point where we have the least amount [...]
Best seal practices for a pump start-up after an extended shut-down Review and follow pump start-up procedures. Rotate shaft by hand to make sure seal faces are not stuck together. Assure bolts and screws are tightened to proper torque settings. Check motor rotation. Vent Pump to assure it is not vapor locked. Assure mechanical [...]
Industrial Fan Repair Project This monster 84" industrial fan is used in an underground mining operation for ventilation. It is powered by a 700hp electric motor. We cleaned, inspected the fan, and re-build/re-wound the electric motor. Call Priest Electric to for more information Call: 208-459-6351
AST RESERVOIR FOR DUAL MECHANICAL SEALS High Performance & Exceptional Value The AST reservior supplies a clean buffer/barrier liquid to a dual mechanical seal without an expensive piping system. Since the AST80 dual cartridge seal has a double balanced inboard seal, the reservoir may be pressurized for tandem seal service. Reservoirs can [...]
How Silicon Carbide Outperforms Tungsten Carbide Silicon Carbide out performs Tungsten carbide as hard faces in most seal applications. It's tribological properties allows for lower coefficient of friction and longer life. In heavy slurry or other extreme pumping conditions the properties are enhanced when you match silicon carbide with a silicon carbide impregnated with [...]
BIG BORE A big bore provides a better machanical seal environment than a standard bore seal chamber and provides better isolation from heat. TAPER BORE A taper bore seal chamber typically provides the best mechanical seal environment. Both types offer the following advantages Increased radial clearance between the mechanical seal [...]
Why Use a Flush Port? It may seem like common sense, however, many users simply plug the port Most applications (ANSI pumps), a line from discharge to seal flush provides circulation to cool seal and flush solids away from the seal. For dirty applications, use a clean liquid flush from an outside source. This [...]
