A long legacy of high-quality engineering

Back in 1957 – the Sundstrand Corporation aerospace division developed a sophisticated compact high pressure water injection pump for the Boeing 707. Sundstrand engineers recognized the opportunity for this new technology in other markets and designed heavy-duty integrally geared pumps and compressors for uses outside of the aerospace industry.


The History of Sundyne

From a legacy of inspiration, an innovative future was born.  Sundyne’s technology traces its roots back to 1957 and the aerospace industry – when Sundstrand Corporation’s Aerospace division developed the first water injection pump for the Boeing 707.  Sundstrand engineers recognized the opportunity for this new technology in other markets and designed heavy-duty integrally geared pumps and compressors for other industries.  Since then, Sundyne has manufactured tens of thousands of centrifugal compressors and pumps, seals, magnetic drive pumps and packaged solutions for complex industrial applications – with products being installed in some of the world’s most remote and demanding environments.

Sundyne can also trace roots back to 1905, when the Rockford Milling Machine Company (owned by Edwin Cedarleaf and Oscar & David Sundstrand) began operations in Rockford, IL.  Twenty years later, mergers with the Rockford Tool Company and the Rockford Milling Machine Company led to the formation of the Sundstrand Machine Tool Company in 1926.

By 1933, the Sundstrand Machine Tool Company sold its first oil burner pump and finalized the development of a wide range of hydraulic pumps, motors and valves, which shaped the future direction of the company.  In 1946, they developed a new variable displacement hydraulic transmission for use in aviation applications – which at that time was called a constant speed drive (CSD).  Once installed into a B-36 airplane, it signaled the start of Sundstrand’s rise to prominence as a manufacturer of components for use in the manufacture of both commercial and military aircraft engines.

When Sundstrand Denver was established in 1955, it became a strategic second source of supply for the constant speed drives.  Sundyne signed a contract to supply the defense industry, as the government insisted upon having multiple manufacturing centers in order to maintain supply chains in the event of a catastrophic bomb attack. The floor plan – which called for a 250,000 square foot facility – was built under the supervision of Joe Triolo and Bud Wallin.  The Denver plant initially employed 700 people, but by 1965 the staff had grown to more than 1,150. During the 1960s, a significant cutback in defense spending sent Sundstrand searching for commercial products with which to replace its dwindling military contracts.

Thanks to the extensive product development programs that Sundstrand instituted for the military, it didn’t take long before inspiration struck.  The idea that would ultimately form the foundation of the Sundyne product line evolved out of a naval research contract that was under the supervision of Ken Nichols and Cliff Hall in the late 1950s. They found a paper outlining the design for a lightweight efficient pump developed for use on the V-1 and V-2 rockets, which had been used widely during World War 2.  The pump design solved a critical design issue that plagued early jet engines, leading to the first water injection pump developed for commercial jet aircraft and sparking a hard shift into new markets for Sundstrand, as the technology was sold to Boeing for use in the 707.

By 1963, Tony Malgieri of Sundstrand Denver’s Development Engineering group realized that the hydraulic performance of the aircraft water injection pump could also be used in applications related to the oil & gas industry.  Malgieri went on to play an instrumental role in building a successful commercial business for high-speed pump technology.

The first high-speed product Sundstrand introduced was a horizontal model intended for use in the water flood market.  The venture failed miserably during field trials in a Wyoming oil patch – but the second attempt proved more successful.  Malgieri coupled the pump’s hydraulic design with a Mechanical Engineering Magazine article that discussed the advantages of an inline-mounted pump that was being developed by a small engineering group at the Shell Chemical plant in Houston.  The resulting design would become Sundstrand’s first high-speed centrifugal pump, which was ultimately sold to Shell Chemical. Shell clearly saw something in the concept; as they went on to provide valuable technical assistance over the ensuing years as Sundstrand established this new segment for its business.

The first in-line pump took nearly a year to build.  The pump ran 24 hours a day for 18 months straight before it was replaced with an improved model.  A second pump (pictured below, on a testing stand) was later sold to Shell Chemical for use at its Ventura, CA location.  The initial startup went so well that one Shell engineer commented that they should “paint it gold for that kind of performance.”  With Shell’s support and testimonial, other companies began to explore the benefits of this novel high-speed pump concept.  By 1964, a total of 67 units had been commissioned in the field.  The design concept had completed the first leg of its transition from being a simple idea to a profitable business.

Emboldened by the success of these initial high-speed centrifugal pumps, Sundstrand began working to expand the product line.  By 1965, compressor designs were introduced, which utilized the high-speed gearboxes developed for pumps, but with different impeller configurations suitable for gases.  Union Carbide became the first customer to purchase the high-speed process gas compressors, signaling the creation of another new market for Sundstrand.

By mid-1965, Sundstrand had 28 representatives and 33 offices scattered throughout the United States and Canada, in addition to four regional managers located in Houston, Los Angeles, Chicago and New York City.  A representative network was also established to cover Europe, under the direction of a European regional manager.  In fact, many of Sundyne’s current representatives – both domestically and in the European market – began long-term partnerships with Sundstrand during this fertile growth period.

When the aerospace industry went back into decline during 1969, cutbacks convinced Aerospace division plant manager Bud Wallin and industrial pump group manager Tom Pope to lobby for the creation of a separate division, complete with full profit and loss responsibilities. Their proposal was ultimately approved, and Sundstrand Fluid Handling began independent operations in Denver, CO, effective January 1, 1970.

At the time of its formation in 1970, Sundstrand Fluid Handling employed 55 people and was shipping approximately 300 units per year. During the first year as a full-fledged division, Sundstrand Fluid Handling developed the Flodyne pump, which was the predecessor of the Sunflo P-1000 which is still sold today.  Over the next decade, both the Sunflo P-2000 and Sunflo blower lines were added to the burgeoning Sundstrand Fluid Handling product catalog, and the 200hp LMV / LMC-311 design was extended to cover 400 horsepower services.

1970 also marked the opening of a Sundstrand Fluid Handling manufacturing plant in Dijon, France.  Focused on manufacturing industrial pumps, compressors and other engineered packaging for the hydrocarbon and chemical processing industries, the Dijon facility signaled Sundstrand’s commitment to the European market and served as a massive boost for the fluid handling division’s capacity. Soon after, Sundstrand Fluid Handling outgrew the office and factory space it had been sharing with Sundstrand’s aerospace group in Denver.  To build out capacity and accommodate growth, the Arvada, CO facility was opened in 1977.

In the interest of continued growth for Sundstrand Fluid Handling, the decision was made to offer a product that would meet the increasingly stringent environmental regulations put forth by regulators around the globe.  Thus, a joint venture was formed with Nikkiso to market the canned motor pump in North and South America.  By 1987, orders were being booked from a wide range of customers, including heavy hitters like Amoco, Phillips and W.R. Grace.  With its efficient, reliable performance ratings, the canned motor pump was recognized as a viable alternative to the competition, and the marketing was concentrated on removing the image of a canned motor as a pump of “last resort.”  Much evolution has taken place since the early days of the canned motor pump. Today, sealless pump concepts – with their streamlined configurations and leak-free performance – have risen to prominence as the industry choice for end users searching for dependability and reliability.

In 1994, Sundstrand Fluid Handling expanded once again, this time through the acquisitions of HMD Sealless Ltd., Kontro and Sine Pump.  This move offered top line growth through the marketing of a new product, which was complementary to the canned motor pump: namely, HMD’s sealless configurations.  Manufactured in England by HMD, these pumps were marketed throughout the United Kingdom, Europe and Asia.  Kontro’s acquisition – as the master distributor of HMD products in North and South America – represented a strategic maneuver for Sundstrand.  The decision to relocate the Kontro operation to Arvada created a “one stop sealless shop,” resulting in a unique new offering for Sundstrand’s existing customer base.

In 1998, Sundstrand Fluid Handling executed another round of corporate acquisitions, bringing ANSIMAG – a leading manufacturer of non-metallic sealless pumps – and MASO Process Pumpen – the “other half” of the Sine business – into the fold.  These acquisitions contributed significantly to Sundstrand Fluid Handling’s market presence, and rounded out the product portfolio.

The next year, massive changes were afoot for Sundstrand Corporation. United Technologies was successful in its bid to acquire Sundstrand, ultimately merging it with the Hamilton Standard division.  The new company, Hamilton-Sundstrand, was headquartered in Windsor Locks, CT, and Sundstrand Fluid Handling was re-christened as Sundyne Corporation.

Since the completion of the merger, change has been the order of the day at Sundyne. As part of Hamilton-Sundstrand, Sundyne was given the opportunity to simplify and focus its resources to enhance its market position.  That focus let to manufacturing enhancements that produced significant improvements in the quality and reliability of Sundyne’s products.

During this time, Sundyne acquired an additional company that further strengthened the product portfolio.  The acquisitions of Marelli along with the introduction of two new product lines (the HMP-7000 centrifugal pump and the Pinnacle compressor) solidified Sundyne’s standing as an industry-leading innovator.

Today, Sundyne is at the top of its game. The company’s heritage of innovation and integrity makes it a global leader in providing process industry solutions. Furthermore, Sundyne’s robust product line and longstanding reputation for delivering top-notch customer support sets it apart as the leader in our field.  Sundyne stands behind every unit it designs, engineers and ships.
