John Crane Launches Global Standardized Upstream Pumping Support System

The Global Standardized Upstream Pumping Support System delivers unpressurized barrier
water for optimal mechanical seal performance and centrifugal pump uptime

CHICAGO (January 18, 2023) ― John Crane, a global leader in rotating equipment solutions, supplying engineered technologies and services to process industries, today announced the Global Standardized Upstream Pumping Support System (GS USP)―an optimized, pre-engineered design based on John Crane’s fluid control expertise and engineering excellence.

The GS USP is a best-practice solution that significantly reduces specification review and delivery schedules and delivers unpressurized barrier water for optimal mechanical seal performance and reliability on seals using upstream pumping technology. This product pairs with upstream pumping seals and by providing a standardized support system, John Crane’s customers will benefit from reduced complexity, small footprint and lower total cost of ownership.

“The addition of a standardized support system to our one-of-a-kind upstream pumping technology makes it easier for our customers to take advantage of the reliability and environmental benefits it delivers,” said Ian Smedley, John Crane Product Line Director, Support Systems. “By reducing complexity and lowering total cost of ownership, our customers will be able to implement this technology on a broader range of applications.”

The GS USP is available in two versions:

  • GS-USP-R: Includes a reservoir of stored barrier fluid; this product is limited to the barrier pressure it can provide to the mechanical seal but contains a stored volume of barrier fluid which allows the seal to run for several hours if the water supply is lost.
  • GS-USP-D: Omits the reservoir and connects the seal directly to the water supply; the pressure-reducing valve allows higher pressure to be passed on to the barrier fluid from the supply.

Features of the GS USP include:

  • Best-practice design delivers clean, low-pressure barrier water for optimal mechanical seal performance and centrifugal pump uptime
  • Instrumentation to suit the user’s monitoring needs
  • Connects directly to site water supply
  • Able to supply a small pressure to the mechanical seal
  • Safeguards against the toughest environments and provides full containment of volatile organic compounds for zero-emission control
  • Streamlined design to minimize footprint and obstruction
  • Allows reliable operation of an upstream pumping mechanical seal to achieve high reliability, zero-emission sealing of volatile or hazardous fluids
