White Papers

The term 'screw pump' is often used generically.  However, this generalization can be a pitfall as it fails to recognize the different products or 'screw' configurations, as well as the uses, advantages and design considerations for each.  The design differences of each screw configuration and pump type make each suitable for different applications and handling fluids with varying characteristics.

Two screw pumps are one of the most versatile and functional pump types, yet they remain largely unknown in the chemical process industry. This white paper highlights best practices and offers design tips for engineers evaluating their pump system and reactor vessels.

For more than 70 years, Colfax has been working with the commercial marine industry to keep pace with changing compliance and regulation demands, as well as helping the industry meet evolving environmental issues.  This white paper highlights one of our latest efforts:  the search for pumping equipment that can meet the demands of low-viscosity, low-sulfur fuels.

For years, rotary pumps have been the standard in delivering high-efficiency, low-maintenance fluid handling solutions for critical applications. However, there's often been a perception that screw pumps are expensive, which prevents many crude oil transport companies from taking full advantage of the built-in benefits for energy savings and reduced environmental impact they offer. The fact is positive displacement screw pumps deliver tremendous cost advantages.

The modern combustion gas turbine is one of the most reliable machines in use and a workhorse of the electric power generation industry. It can be on-site and running in a relatively short period, providing quick additional power capability when needed.

The impetus for the development of the Babbitt lined steel rotor housing has its roots with the U.S. Navy, back in the late 1960s/early 1970s. It was at this time that the Navy undertook a major fuel conversion, from Navy Special Fuel Oil (NSFO) - an approximate blend of 60 percent Bunker C/40 percent distillate fuel - to a 100 percent distillate fuel.

In mechanical engineering, like in other fields, the total cost for owning and operating a pump unit or installation is the focus of increased attention.
