Hidroman, which aims to provide uninterrupted and safe services to its customers with its operations throughout Turkey and Europe, defines a perfect customer experience as product reliability and after-sales service reliability.

Hidroman, which has made being with its customers throughout the life of the product in order to create brand loyalty a part of its corporate culture, organizes the services it offers within the scope of After-Sales Services under four main headings as supervision and assembly, commissioning, maintenance-repair and original spare parts supply. Supervision service; It covers consultancy and training services on issues such as efficient hydraulic equipment selection, rules to be considered for correct product installation and connection of the pump with other installation equipment. After the installation of the device, the commissioning service is also carried out by Hidroman’s expert technical staff.

In hydraulic equipment technologies used in many different areas, malfunctions may occur over time due to operating conditions. During the 10-year life of a piece of equipment, the initial investment cost and repair expenses constitute 10-15% of its total cost, while the remaining expenses are due to energy consumption. Hidroman examines all processes from the selection of the hydraulic system to all the equipment on which the hydraulic system will operate, and offers “efficient system solutions that aim to minimize energy consumption”.

In addition, with preventive and protective maintenance agreements, it aims to reduce the risk of failure of the device, extend its life and ensure that the device operates with high efficiency and low energy consumption.

Thanks to the advantages offered by Hidroman with preventive and protective maintenance services, the budget allocated by its customers for maintenance pays for itself in a short time.

In businesses where uninterrupted service is important, Hidroman intervenes in malfunctions in a short time and minimizes damages caused by labor losses. Offering its customers a 10-year original spare part guarantee in the hydraulic systems it sells, Hidroman delivers tested original spare parts from stock in case of malfunction, shortens malfunction periods and eliminates disruptions that may occur during this period.

Hidroman After-Sales Services department stated that they offer annual maintenance services in accordance with the needs of the business. It states that their aim with maintenance services is to increase hydraulic system efficiency, ensure continuous operation of the hydraulic system and to detect, monitor and prevent possible malfunctions in operating equipment and devices by using technological measurement, control, analysis and monitoring devices.

We aim to standardize the service provided by our authorized services by inspecting them at certain intervals.
