These guidelines will help extend packing life and reduce downtime. No shortcuts should be taken if a plant wants to achieve reliable compression packing performance. However, reliability and a longer life can be obtained by following some basic guidelines. This is important because, the better the performance and reliability of a fluid sealing program, the […]
All DFT Check Valves undergo rigorous tests to ensure they meet industry quality requirements. Check out this handy infographic to learn about their diligent testing.
Electro Static Technology (EST, AEGIS®) guarantees that AC induction motor bearings will not fail from electrical fluting damage when AEGIS Shaft Grounding Rings have been installed with new bearings in accordance with our recommended best practices, as published in the AEGIS Bearing Protection Handbook (current edition).
Pumping applications can range from being simple – fluid transferring operations that move product from one tank, container or truck to another – to complex and sensitive, such as chemical manufacturing and refining operations. Because of the importance of the pumping process in the myriad transferring operations in the industry, facility operators need to identify […]
Part 1 of this series discussed in detail how to accurately calculate the reactions induced by pressure transients that travel at acoustic velocity in either liquid or gas piping systems. Part 2 applies these methods to a variety of realistic examples to further illustrate their use and to demonstrate areas in which traditional or simplified […]
Changes in the operation of piping systems – like valve closures or pump starts – propagate pressure waves that travel at acoustic velocity throughout the fluid. These pressure waves have considerable effect on forces, potentially generating dynamic loads upwards of 10,000 lbf (50 kN) in common configurations. Some estimation methods used in industry for estimating […]
Basic Principle The radial vanes cause pumpage, let’s say water, to rotate in the cylinder. Centrifugal force moves water towards the outside of the cylinder. Since the water can’t move outside the cylinder, it moves upward, and the water will rise from D1 to D2 on the outside edge. Vacuum is created because the water […]
The air-operated double-diaphragm (AODD) pump has been a godsend for operators in the industrial space who need a cost-effective, reliable, and safe pump technology for a wide range of liquid-transfer processes. These processes can include such rough-and-tumble utilitarian applications as those found in the mining, water/wastewater, and oil and gas industries, as well as those […]
Long packing life requires proper packing installation, shaft stabilization, and thorough equipment inspections. By David Brewer The stuffing box of a pump houses a gland that compresses the packing used to seal the pumped fluid. It prevents leakage along the shaft that passes through a hole in the pump. The reliability of the stuffing box […]
Leading maintenance in a plant, mine, or mill takes a lot of effort. Emergency work comes in a steady stream, some are breakdowns, and other work is just “honey-do-jobs.” The workforce needs to be managed, the budget must be met, and equipment reliability must be maintained and hopefully even improved. This guide will give you […]
This is an overview of the implementation steps in a typical Preventive Maintenance (PM) improvement project. Most of the processes can be applied to a greenfield process. In fact, that may be easier to improve than an existing PM process.
