FTS Birth / FTS Future

Introduction of FTS invention

Lee, Man-soo, the inventor of the Flexible Transmission Shaft (FTS) is a mechanical engineer who majored in mechanical engineering at Seoul National University in South Korea. He acquired his professional engineer's certificate in the industrial machinery in 1979, developing a long and distinguished career in a diverse range of machinery-related arenas. Lee established MONAS PUMP Co., Ltd. in 1998, and has managed the company ever since, serving as its current President.

As a specialized manufacturer of the Progressive Cavity Pump, MONAS PUMP Co., Ltd. has established reputation for its product quality both at home and abroad.

The Progressive Cavity Pump, also called as the Eccentric Screw Pump, or the Moineau Pump, (named after its French-born inventor), is a special, positive displacement rotary type pump, designed to transfer high-concentration and high-viscosity liquids.

The pump exhibits special construction structure. Due to the special screw geometry in the Rotor and Stator, in charge of the liquid transfer, the rotor axis performs an eccentric movement, leading the transmission of driving power from the drive shaft to the rotor not in a straight line. It follows that two Universal Joints needed to be installed between them to operated the machine successfully.

The structure of these two Universal Joints is not simple, even when used for general purposes. Things are more complicated when they are applied to the Mono Pump. In consideration of the fact that the Universal Joints needed to be operated in the liquid transferred by the pump, the Joints require a completely sealed construction to prevent outside liquids from flowing in. This presents a large burden in pump manufacturing.

It follows that Universal Joints are the most frequent causes of breakdowns of Mono pumps, and have become the crucial factor in durability limitations. With a number of years of work searching fundamental solutions to the problem, Lee, Man-soo finally invented the principle of the Flexible Transmission Shaft, based on his rich experiences in the field.

In January 2006, Mr. Lee registered a patent for the FTS in Korea, placed it under the PCT process for international patent registration on August 12th, 2005, and is currently applying for patents in major global regions, including the EU and the U.S. & Asia, etc

 With the aim of putting the FTS into practical use, Monas Pump strived for of technical developments, finally developed the special machine tool exclusively for the processing of waveform grooves in the FTS.

In addition, Monas Pump has been successful in developing the prototype of a Mono Pump, obtaining satisfactory results from its performance tests. The company currently pours every effort to mass-produce it for commercial use.

In addition to the Mono Pump, MONAS is moving forward with research on the unique characteristics of the FTS movement, and on how to maximize the application of the FTS, hoping to develop ripple effects that the FTS will create for the overall industry.

Considering the extensive range of possible implementation possibilities of the FTS, MONAS plans to share its technology with others in the industrial field, by issuing licenses to companies seeking to use it, rather than pursuing commercialization of all products independently. The company intends to introduce the FTS and distribute it widely, hoping to contribute to major innovation and development in the machinery industry. We look forward to hearing from a number of interested parties, and thoroughly welcome any requests for consultations regarding the FTS.
