Dry Split Seal a Solution for High-Temperature Mixing Tanks

Use of bearing sleeve material helps the long shaft run true.

Chemical attack is a destructive force in any high-tech manufacturing process. For TIMET’s Las Vegas, Nev., plant, the force was presenting itself during the high temperature mixing of titanium tetrachloride (TiCl4), known in the industry as TiCL.

The Vital Role of Valve Springs in Power Pumps

When calculating maximum speed, power pump valve springs are an under-valued factor.

History tells us that a fellow named Ctesbius built a reciprocating power pump in about 150 B.C. on the Nile1. It sat near the surface of the river, was driven by an undershoot waterwheel and pushed river water into an irrigation system.

The Evolution of Pump Control

Advanced motor protective relays provide superior protection for motors and pumps.

For years, motor overload relays have been used to protect pumping systems. Traditionally, they monitored current to protect the motor and relied on separate electromechanical sensors, such as flow meters or pressure gauges to protect the pump.

What Are the Basics of Gas Lubricated Seals? (Part Two)

Last month's Sealing Sense provided an overview of pump gas seal benefits and general design issues. This article will discuss some application conditions that must be considered when applying gas seals to pumps.

AC Motor Torque

As a follow up on my AC Motors series, I thought it would be a good idea to provide a short overview of work, power and torque as it applies to the AC motor. I will provide a reference to a more in depth study at the end of this article.
