Electromechanical Services Ltd(EMS)
The Mechanical Department (1950 – 1960) constituted the foundation for the subsidiary - EMS Mekorot Projects (EMS). The scope of activities increased immediately after the establishment of the State of Israel. The Department’s structure included the Electrical Division, the Pumps Division, the Diesel Engine Division and the Electrical Stations Assembly Department. All these departments provided their services to the Company’s field units and were also in charge of the development work (pumps, electrical boards), assembly as well asmaintenance, if required.
In January of 1959, a decision was made at the Company’s management level to allow the Mechanical Department to manage its own affairs independently and to also carry out work for external entities. In 1961, EMS (Electromechanical Services) Ltd. was registered as an independent company. The subsidiary transferred its shares to the parent company in exchange for the buildings and equipment it obtained from the parent company - Mekorot Water Company Ltd. . During this period, the company’s activities focused on the manufacture and installation of electrical pumping equipment (including electrical boards) for water, fuel and sewage project projects, the installation of chlorination equipment and even the installation of command and communications systems.
In 1963, at the time that the National Water Carrier was under construction, 85% of the Company’s work was executed for Mekorot. The Company’s unique field of operations offered its employees employment stability ; however, the Company and it’s officials were forced to increase the scope of the orders. Management feared that the parent company’s scope of work could not justify the subsidiary’s large scale employment ; and consequently, efforts were made to seek out external work. Such efforts were successful, and the Company implemented projects for the sugar factory in Afula, for the Yuval Gad prefabricated housing company, and even for a sugar factory in Iran. EMS Electromechanical Services Ltd., in cooperation with the ORT Organization and the Ministry of Labor, established an industrial school where students were trained for work in the Company’s fields of employment. The school was operated until the end of the 1970s and some of its graduates were employed by EMS and Mekorot, following their military service.
EMS was also engaged in rainfall enhancement operations, through the seeding of clouds with silver iodide. This activity featured both experimentation and operation, and researchers from the Hebrew University provided support for the operations at all times. In addition, a company acted on behalf of EMS to repair and calibrate water meters.
EMS, as well as Mekorot and its subsidiaries must constantly contend with the competition from the private sector that has developed in these fields. Nevertheless, EMS held its own and successfully dealt with the hardships of the reorganization and economic changes executed at the parent company. During the last reorganization (which ended in 2008) and the establishment of EMS Mekorot Projects Ltd., EMS became the heart of the operations.
EMS has invested considerable resources in the field of pumps. In the days of the Kishon project Project, and even before its operation, pumps and pumping equipment were ordered from external companies for Israel’s water project industry. Such was the case during the first few years of the company’s existence, until the company increased its activity, specializing in the design, manufacture and supply of pumping equipment for the shallow and deep boreholes that were drilled for the Company. The extensive experience accumulated by the Company in this field led to many professional success stories, which have enabled the company, to install pumping equipment at a depth of over 500 meters.
Until the beginning of the 1960s, Mekorot used of pumps purchased primarily from the U.S., and invested a great deal of effort in adapting them to its pumping equipment. Subsequently, EMS began to develop various models of pumps, to meet the unique requirements of the Israeli water industry. The EMS pump development process included cooperation with IBM, which developed a 3-D model for the correct and precise design of the pumps.
The first model developed by the Company featured a discharge rate of 125 cu. m. per hour, and was followed by models of various discharge rates and of various diameters. From the beginning of the 1980s until the present time, EMS has developed more than 80 models of pumps of various diameters, from 6" to 40", and of discharge rates of up to 6,300 cu. m. per hour.
In addition to the detailed design, the various development projects included pumping trials and the design of hydraulic models at the world’s most advanced institutes in this field, the purpose of which was to adapt the pumps to the boreholes, to the (booster) pumping stations and to suit the varied quality of the water. Over the years, EMS has registered a number of patents in the field of pump development.
In order to manufacture pumping equipment (columns pipes), EMS used a Landis lathe was for 30 years. This machine served the Company faithfully until the 1990s. As a result of operating problems making it difficult to maintain quality of the products, a Korean Daewoo CNC lathe was introduced into the factory in the 1990s. Thanks to the introduction of this lathe and lifting equipment adapted especially to the lathe, the company once again became the leader in the field of column pipes? manufacturing technology.
The Company did not focus solely upon the development of pumps and related equipment. Because EMS is also engaged in the dismantling and assembly of pumping equipment and trial pumping, it constantly needed to improve its methods. As a result, a model was developed for the assembly of equipment weighing up to 70 tons. Suitable equipment was purchased, including block and tackle and hydraulic cranes, leading to a reduction in the dismantling and assembly process times
