At Vremac Cylinders we have been involved in the engineering and production of cylinders, accumulators and swivels from the moment our company was founded over 60 years ago. Alongside our standard range cylinders we supply custom-built cylinders. Over the course of the past 20 years Vremac has steadily shifted its focus more towards the production of custom-built hydraulic cylinders. We specialise in bores of up to 1000 mm, piston rods up to 700 mm and cylinders with a longer stroke, up to 15,000 mm.
Vremac Cylinders understands your requirements and has the ability to provide suitable solutions. Our engineers provide proven solutions for the technological requirements of your projects. Our job is to make your hydraulic movements possible.
Vremac Cylinders is one of the market leaders in the field of cylinders and can provide:
- High end piston rod finishing
- Adjustable end cushioning
- Accumulators and swivel joints
- Positioning measurement systems
We are fully certified and have a solid track record and reputation when it comes to expertise, quality, high standards and service. Our clients can rely on our short lead times, because all manufacturing can be done in-house. We make use of dedicated metal cutting and robotic welding machines for our operations.
Vremac Cylinders is the perfect partner for all your hydraulic cylinders, piston accumulators, swivels and heave compensators.

Research & Development
At Vremac Cylinders we are continuously investing in research and development. Over 75% of the cylinders we manufacture, are (partly) new engineered products. We are proud to say that we always offer a solution that meets the requirements of our client. Our reliable designs are based upon and backed by research.
One of our important values at Vremac Cylinders is co-creatorship. From the start of a new project, our engineers are in close contact with our client’s engineers. Together, we work toward the development of the best solution. After delivery of the product, we remain in close contact with our clients to monitor the performance and provide maintenance and repair services.
Manufacturing and QA
Vydraulics guarantees high-quality products and ISO 9001 standard. With our extended knowledge of the process and a well-equipped production facility, every step of producing a cylinder can be done in-house. To remain flexible we also have surrounded ourselves with a reliable network of certified suppliers.
We understand the complexity of manufacturing a high quality product. Assembling a cylinder, but also an accumulator or a swivel joint is an accurate job. Dealing with limited tolerance and heavy components demands craftsmanship. Our production employees are well-skilled and extremely motivated to deliver a high quality product.
All cylinders are tested to the design and test pressure. Simultaneous to the test, the final inspection and measurement check of a cylinder takes place. Clients are welcome at our production facility to witness the test program and final inspection.
ISO 3834
ISO 3834 is an internationally recognised quality standard that describes international welding standards that focus on quality assurance requirements for fusion welding of metals. These standards complement ISO 9001 certification, in the interest of customers, to provide greater assurance that welding technology products meet all specified requirements.
ISO 3834 specifies requirements for quality assurance of welding during production or manufacturing processes and emphasises the importance of qualified welders, appropriate equipment, proper procedures and good-quality materials to ensure the integrity of welded structures. An ISO 3834-certified company is supervised by an accredited inspection body. Regular audits are carried out to check compliance with all requirements.
There are different levels of ISO-3834 certification.
ISO 3834-2 describes the most comprehensive quality requirements for fusion welding of metals. The standard covers a wide range of aspects to ensure the integrity and quality of welded products. In particular, this standard aims to ensure that welding operations are carried out effectively and consistently, meeting the set requirements and standards throughout the welding process. This certification indicates that the company has mastered the highest level of quality in the welding technology industry.
While ISO 3834-2 provides comprehensive quality requirements suitable for critical welding applications, ISO 3834-4 offers a simpler approach tailored to less demanding welding scenarios. ISO 3834-4 still emphasises the need for effective quality planning, personnel competence and documentation, but with less complexity.
Understanding the differences between these standards is crucial to selecting the right one based on specific welding requirements and ensuring compliance with international quality standards in welding operations.
Vremac always works according to the ISO 3834-4 standard, unless otherwise agreed with the customer. This is recorded in the quotation and order confirmation.
Service & Repair
Repairing hydraulic cylinders involves more than replacing the broken parts. With over 60 years of experience we have sound hydraulic knowledge and extensive experience with cylinders in all kind of applications. We offer preventive maintenance, renovation, spare part management and repair onsite or in our workshop.
