Quality: A Constant Concern for Customer Service

At CLEXTRAL, Quality, Safety and the Environment (QSE) are fundamental values embodied in our everyday activities, with the permanent objective of customer satisfaction. The simplicity and robustness of the DKM pumps, with their ISO 9001 and ISO 14001 certifications, ensure maximum availability of the installations.

In 1996, CLEXTRAL adopted an organisation compliant with Quality Standard ISO 9001 and committed to guarantee the conformity of the products delivered to the customers. In 2005, thanks to the motivation and enthusiasm of all its teams,DKM – Clextral also decided to introduce an environmental management system compliant with ISO 14001, DKM – Clextral having for many years acted as a responsible enterprise devoted to limiting the impact of its installations and technologies, which are sold worldwide, on both the natural and the human environment.

DKM pumps are compliant with the American Petroleum Institute’s international standards API 674 and API 675, which extend well beyond the oil and gas markets and the chemical industry. Likewise, DKM pumps can be installed on vulnerable or SEVESO-listed industrial sites, as they satisfy the specific provisions of ATEX Directive 94/9/CE.

Having obtained certification from CEFRI (the French Committee for Company Certification), certification, DKM – Clextral extended its activities to the maintenance of pumps installed in nuclear power stations. Its personnel receive the appropriate training both for their own protection and also to improve the prevention of risks attached to working in nuclear installations.

DKM – Clextral is strongly committed to Quality, Safety and the Environment, and hence develops and manufactures its products with the objectives of sustainable development and the wellbeing of its personnel.


The Quality Assurance Manual meets the provisions of ISO 9001 and can be consulted by customers on request.
