VELJAN Hydrair Private, Ltd.

From Wikipedia, the free encyclopedia

VELJAN Hydrair Private, Ltd. is an international hydraulic component manufacturer.

Beginning in the 1960s, VELJAN has manufactured a variety of hydraulic components and today manufactures hydraulic vane pumps, hydraulic vane motors, hydraulic directional & pressure control valves, hydraulic cylinders.

In the country of India, VELJAN is also known as Denison Hydraulics India. The licensing agreement between VELJAN and Denison, in the 1970's, provided the right to use the Denison name within the country of India. The licensing agreement does not allow for the use of the Denison name outside the country of India, and so exported product is known only as VELJAN product. The product is quite understandably a direct replacement for Denison product because the product is the same.

Denison Hydraulics is currently a subsidiary of Parker Hannifin (since 2003).

Applications include but are not limited to: injection molding machines, hydraulic power units, hydraulic presses, and a litany of mobile applications. Though based in India, VELJAN has been active in North American Markets since 1999.

VC Janardan Rao is the Chairman & CEO of this privately held company. It is based in Hyderabad, India.

[edit] History of Denison Hydraulics

Denison Hydraulics Inc., originally known as The Cook Motor Company, was founded in 1900 in Delaware, Ohio, as a manufacturer of heavy duty industrial gasoline engines. They were big, heavy, and only single cylinder. For example, a typical 50 HP engine weighed 3 tons.

After World War I, Mr. Cook wanted to retire. Bill Denison took over just as the engine market was dying. He continued to operate under the original Cook Motor Co. name. In 1925, Mr. Denison invented a hydraulic car pusher. It was designed to slowly move cars full of clay-ware through a kiln - decidedly the newest invention of the day owning over 80% of the hydraulic market. It was the first hydraulic machine.

Shortly after getting the new car pusher developed, there was a business recession. The new art of hydraulics pulled them through. The name HydrOILic was then used to identify this new method of power transmission. Cook Motor Company went into receivership.

Bill Denison was able to reorganize the company as the Denison Engineering Company'. The company survived the Depression, although just barely. One of the early products included the Billet Pusher and the "Compact" Power Unit.

In 1933, a fire destroyed the plant in Delaware. The Budd-Ranney Company had property at the corner of Chestnut and Marconi Blvd. Denison operated under contract with Budd-Ranney Engineering until 1935. Denison then acquired Budd-Ranney - which was maintained for a while as a separate subsidiary. Prior to WWII, Denison was contacted to help with developing test stands and presses to assist in making weapons and aircraft. Presses increased production of airplane engine crankshafts by four times. Presses also permitted "safer" manufacturing of high explosive shells.

During the war years, Bill Denison bought facilities throughout Columbus and a research center in Powell, Ohio. One of the properties Denison purchased was a property on Dublin Road which would provide for special military needs. Aircraft test stands permitted testing complete hydraulic systems while on the ground and testing hydraulic operated fuel transfer valves for airplanes. Special vacuum chambers tested spark plugs and magnetos.

Suddenly Denison needed to re-adjust to the civilian market. Denison achieved a reputation of being innovative and aggressive. Denison was still known as Denison Engineering. In addition to Multipress, another division was responsible for the manufacture of hydraulic components for the general industry. A separate division was dedicated only to Research and Development. Ideas that were discussed during the "War Years", but shelved, due to lack of time and manpower, now came "off the shelf".

Additional controls for Multipress and many new products for the hydraulic industry were developed. In fact, Denison salesmen had to teach their customers about the merits of hydraulics. In 1945, a new line of high speed, lightweight aircraft pumps were introduced and in 1954, Denison, in cooperation with the U.S. Government, purchased a factory at 425 Sandusky St., Delaware, Ohio(USA).

In addition to other products, the intent was to manufacture aircraft pumps. In 1955, Bill Denison sold his business to American Brake Shoe. He remained president and resided on the Board of Directors. In 1956 the aircraft pumps were moved to Rochester, New York and later Oxnard, California. Finally, in April of 1962, the business came to Marysville, OH(USA).

In July 1962, Denison takes shape and begins to look like a factory. In September of 1962, the entrance was being finished. In October of 1962, the facility in Marysville was almost complete. Still operating as American Brake Shoe, the facility was initially used for manufacturing piston pumps. The Multipress group soon moved in. After the Multipress moved out, the manufacturing facility returned to piston pump production providing special products for the government.

In 1966, American Brake Shoe changed their name and identity to ABEX. And in 1968 merged with Illinois Central to become IC Industries. Throughout the ABEX and IC years, Denison continued to be a leader in the development of high performance products. Then in the 1970s, Denison(ABEX/IC) licensed VELJAN Hydrair Private, Ltd. to make hydraulic vane pumps and pressure controls for the market in India, and Denison had a controlling stake in this business venture. Denison, while still operating under ABEX / IC, became heavily involved with Marine applications. In 1986, ABEX / IC sells the Denison division to a Swedish manufacturer of Radial Piston Hydraulic Motors: Hagglunds.

As business slows during the recession of the 1980s, Hagglunds Denison was forced to close and sell several factories. Burgess Hill, England: Delaware, Ohio: Columbus, Ohio. The Marysville, OH facility becomes the Corporate Headquarters, but it was also subject to severe cutbacks.

Denison split into two groups in 1991: Hagglunds Drives and Hagglunds Denison. In 1993, Hagglunds sold the Denison portion to three private investors. Hagglunds remained a customer of Denison, but no longer retained ownership in the company. The company name was then changed to the current Denison Hydraulics Inc.

In 2003 Denison Hydraulics Inc. became the wholly-owned subsidiary of the Parker Hannifin Corporation. Denison had changed parent companies several times over the course of some thirty years, and had slowly divested itself of the initial majority interest it had in VELJAN. Today, VELJAN is a privately-held, independent company serving several international markets.
