  Water hammer — a high-pressure surge or wave created by the kinetic energy of the moving liquid — is not only a system issue, but primarily a safety concern. Understanding the nature and severity of water hammer in a steam-and-condensate system will allow prevention of its destructive forces. A better understanding will also help with the introduction of preventative measures into system...

Reduce the problems associated with handling hazardous liquids by following these guidelines Pumps are one of the most ubiquitous items of equipment found in chemical processing plants. Often, they are used to transfer hazardous liquids, such as flammable, combustible, toxic and corrosive chemicals. In order to ensure safety during pumping, certain design and operating practices should be followed. This...

Knowing the options in fluid-circulation designs helps in the selection process Over the past few decades, hundreds of seal geometries and a fair number of seal categories have evolved. Recently, the distinction between single- and dual-mechanical seals has been brought into focus by heightened safety and environmental concerns. Dual seals are often selected where safety is of paramount concern. To aid in...

    It has been said that pumps are the second most common piece of industrial equipment next to electric motors. There are literally millions of pumps in use around the world handling thousands of different liquids. With the many types of pumps available, selecting the proper pump for any given application can be complex. The pump selection process is, in large part, matching a particular...

    Recent strong activity in the global chemical process industries (CPI) has brought good news for pump manufacturers, among other equipment vendors. "There's tremendous growth in the chemical, petrochemical and oil and gas markets, and business for us is good," says Dave Flinton, product & marketing manager with ITT Goulds Pumps (Seneca Falls, N.Y.). But both engineering...

    The 23rd International Pump Users Symposium returns to the George R. Brown Convention Center (Houston, Tex.) this year on March 5–8. Known as the meeting organized by pump users for pump users, this show is guided by an advisory committee that is made up of recognized leaders in the pump community. In addition to a wide variety of exhibits, the program provides an opportunity for...

    This versatile pump is a compact contortionist   The E8 3/8-in. Mini-Matic pump (photo) weighs just 3 lb but can pump as much as 6.8 gal/min and deliver pressures up to 100 psi. It can be mounted upright, sideways, or inverted, thereby making the pump adaptable to uses in, for example, chemical batching and dosing, adhesive applications, ink and pigment dispensing, foaming applications...

    In widespread use throughout chemical process plants, centrifugal pumps are often employed (and taken for granted) in severe service conditions. Consequently, it is hardly surprising that problems can arise during their operation. A major difficulty facing the chemical process industries today lies in the limited number of people who have enough skill and experience to diagnose and rectify...

Conventional magnetically coupled centrifugal pumps can only survive dry running — if at all — by using costly materials and complicated constructions, according to Christian Wallrodt, sales manager at Wernert-Pumpen GmbH (Mülheim an der Ruhr, Germany; Such pumps’ bearings are traditionally located radially within the inside of the pump. If the flow is...

Mechanically driven diaphragm pumps (MDDPs) are widely used for metering applications in the chemical process industries. But because the pressure difference between the drive and the delivery side gives rise to tensile loads in the flexing zone of the diaphragm, MDDPs are limited to low-pressure (<12 bar) applications, and the additional stress reduces the lifetime of the diaphragm. Whereas...
