Hydraulic problems are meant to be resolved

Our engineers have never encountered a problem that they could not resolve with their years of experience, ingenuity, and CAD expertise. For our customers, this means that an effective and durable hydraulic solution will always be found.

In order to do this, it is essential that WDH tracks, maintains and continues to develop its level of knowledge, skill and craftsmanship. Our own team of engineers plays a crucial role. They are passionate about hydraulics and signal interesting issues faster. All technical information is absorbed like a sponge and this knowledge and expertise flows freely throughout the organization.

Our customers benefit from this approach. We directly understand your problems and will take the necessary steps to resolve them. Combining flexibility with accessibility, is our strength and that really makes a difference.

Quick response time and professionalism

Our team of enthusiastic employees knows how to respond and act swiftly. Our short lines of communication are very effective and they are embedded in our company DNA. We just want to be the very best. We want to be the best when it comes to our products, whether they are customized hydraulic cylinders, swivels, piston accumulators or related products. We also want to be the best when delivering services, such as engineering, overhaul and modification, and machining operations.

Not only efficient and effective but also sustainable

For many customers in the maritime and industrial sectors, sustainability is important. This requires an effective and efficient production process. A process which uses durable manufactured semi-finished products and components is crucial.

Total Cost of Ownership (TCO) is an important parameter in our approach. We go for the long term and contribute to sustainability and profitability for our customers, minimizing unexpected costs.

WDH cylinders meet the demanding requirements of internationally recognized authorities such as Lloyds, Veritas, DNV, ABS and CCS. To ensure product and process quality, WDH is also ISO 9001: 2015 and ISO 3834-2 certified.

Each cylinder comes with a Manufacturing Data Record. In this data book, all important information about the materials, components and recorded test data is documented.

Lloyd’s Register Netherlands has given WDH authorization to mark materials with a 3.1 or 3.2 certificate. The process of remarking improves material identification, and leads to traceability of the materials used in the individual cylinders. Upon request we provide a certificate of approval and remark statement in your products.

Stamping and remarking applies to materials with a 3.1B or 3.1C certificate (according to EN 10204.1991) and materials with a 3.1 or 3.2 certificate (EN 10204: 2004). Remarking is done in accordance to the G0304 at our own production site.
