A brief history...

With the invention of the Sims Pump Valve for use in reciprocating pumps, Sims was launched in the Red Hook section of Brooklyn in 1919 by Admiral Sims and his brother. Growth necessitated first a move to downtown New York and later to the company’s present address in Hoboken, New Jersey.

From the outset, the company offered its unique guarantee of customer satisfaction. Introduced by the founder of Sims, the guarantee continues today as an integral part of operations. In the first four decades that followed, Sims was steadily at the helm providing maritime and other industries with valves of bronze, stainless steel and monel. The inherent clattering of the reciprocating pump valve caused by the pump rotator pounding against the disk lead to the invention of one of the first composites on the market in 1945, the Simsite® disk.

Recognizing that conventional metal impellers were subject to electrolysis, corrosion, erosion, and unbalance problems when used in services such as salt or brackish water; Sims, in 1955, introduced the first Simsite® Casing Rings and Impellers. The highly innovative use of this structural composite material, patented and invented by Sims, was a great success. It outlasted the life expectancy of bronze and stainless steel impellers and rings by years and extended the entire pump life.

The Simsite® structural composite technology continued to improve over the years, making the composite stronger, more resistant to chemicals and abrasion and capable of withstanding higher speeds and higher temperatures (400 degrees F).

  • In 1985, Sims manufactured the First Structural Composite Pump, all Simsite®, Vertical Pit Pump, and Sims won the Innovative Product Award for these pumps in 1990.
  • In April, 1994, Sims received the honor of approval from the United States Navy for Composite Centrifugal Pump Internals. Simsite® was tested and qualified for centrifugal pump replacement parts and was the first composite pump company to be certified.
  • In 1995, Sims manufactured the Largest Composite Pumps in the world two Simsite® vertical turbine pumps for Potomac Electric Power Company.  They are 40 Feet long and 3 Feet in diameter.
  • In 2001,  Sims designed the Fastest Running Structural Composite Impeller for Raytheon Radar Cooling Systems.  The impeller runs at a speed of 12,000 RPM.
  • October, 2002, Sims introduces the First Structural Composite Vertical In-Line Pumps.
  • In June 2003, Sims became the First Company to have Composite Pumps and Baseplates, Shock & Vibration Qualified by the United States Navy.
  • December 2003,  SIMS becomes Shock and Vibration Qualified for the US NAVY Standard Composite Pump Line.
  • In 2004, SIMS designed a Complete Line of SIMSITE® Structural Composite Pumps for the US Navy.  All sizes are U.S. Navy  Shock and Vibration Qualified.
  • In 2005, SIMS designed and Shock Qualified a SIMSITE® Structural Composite In-Line Ball Valve for the US Navy.
  • In 2006, SIMS manufactured the Largest Structural Composite Centrifugal Impeller in the World.  This huge impeller was installed in a cooling tower pump for Puerto Rican Electrical Power Company in 2006.  The impeller is 50” in Diameter and consumes 2000 horsepower.
  • In 2007,  SIMS designed and Shock Qualified a SIMSITE® Structural Composite 3-Way Diverter Valve  for the US Navy.
  • In 2007, SIMS engineered a new type of SIMSITE® Structural Composite Replacement Bowls for vertical turbine multi-stage pumps.   These stages are suitable for a wide range vertical pumps from 4” bowls up to 20” bowls.  The maximum operating pressure of these pumps is 600 psi.
  • In 2010,  Sims designed and engineered the First Structural Composite Anti-Heeling Pump manufactured completely from SIMSITE® Structural Composite, for NCL Cruise lines.
Two traditions still go hand-in hand: the guarantee that stands behind each Sims product and the more than 90 years of service and experience offered by Sims.
