Split Flow: Save energy, reduce carbon emissions

More than 33 states have enacted legislation mandating targets for the reduction of greenhouse gasses. Political pressure is mounting on the oil industry — and industries across the board — to reduce greenhouse gasses that contribute to global warming.
Split Flow API centrifugal pumps provide a solution to oil refiners.


> Why Split Flow: One Split Flow pump can do the work of two standard pumps, at significant energy and cost savings. The patented Split Flow feature allows the use of smaller motors, thus lowering electricity usage. Less kilowatt consumption means less draw on the electricity plants that power the pump fleet. This means less carbon dioxide emissions — whether it is from the burning of coal or even the relatively clean natural gas, the main feedstocks for power plants.

> In action: Two Split Flow pumps are currently in operation at the Shell refinery in Martinez, Calif. since June 1996. Use of the Split Flow pumps results in an annual kW saving of about $25,000.

> In a nutshell: Split Flow technology can be applied to save significant capital and operating costs for API pump installations. This savings is enjoyed by the refiner, the customer and the environment. Quite simply, Split Flow is a more efficient pump selection for dual service applications. It saves energy, and thus reduces carbon emissions.

Welcome to
The site is intended to display the many features of this important pump innovation, in addition to highlighting its new applications in an era of heightened environmental concern.

This Web site is intended to inform process and pump engineers that the Split Flow feature is available as an option with API Standard 610 pumps when used for dual service. This option allows use of smaller motor drivers — resulting in energy savings — and use of two pumps instead of four to limit redundant multiplicity.
