It is well documented that the proper operation of vertical centrifugal pumps is greatly dependent upon the entire pump/piping system, which includes the piping geometry and the system operating conditions. Oftentimes, ...

While other segments of industry have slowed the biotech and pharmaceutical industries are emerging as strong growth industries. To participate in this promising growth the mechanical seal manufacturers have begun to focus ...

APIs recent release of Standard 682 Second Edition and the pending release of API 682 Third Edition and ISO 21049 represent a major revision to this standard. These revisions have greatly expanded the scope of the standard ...

Energizing research and development on pumps in today’s emerging global and environmental context is envisioned as a major feature of the pump industry in the next quarter century. The mission for how to realize this vision ...

When working around equipment for a long time, it is easy to become accustomed to it working as it should. It can make us numb to potential problems, especially is they come on gradually. This tutorial will present some ...

Subsea processing gives pump engineers permanent technical challenges due to the comprehensive specifications that often stretch the proven limits of technology. It is particularly true for pumps that have to boost a ...

Installation and startup of centrifugal pumps and drives can be a stressful time. It involves a coordinated working relationship with several crafts - foundation, contractors, pipefitters, welders, millwrights, startup ...

This tutorial deals with pump cavitation, discussing various net positive suction head required (NPSHR) criteria, net positive suction head available (NPSHA) margins and impeller life expectancy. It gives an introduction ...

Specifications of some pump users limit the suction specific speed (Nss) with the objective of selecting more reliable centrifugal pumps. This limitation is based on a statistical evaluation of pump failures published by ...
