Mechanical seals
We design our mechanical seals in 3D according to customer drawings, samples or our own concepts. With extensive specialist knowledge in the field of pump and mechanical seal technology, our experts produce unique mechanical seal concepts tailored to your requirements and implement complicated conversions or adaptations. We guarantee short response times as well as flexible and dynamic customization options throughout the entire order processing process. If you wish, you can easily get in touch with the responsible employees at any time and put your questions and concerns directly to the right person.
Standard mechanical seals:
Whether rubber bellows, single spring, sinus spring, or metal bellows mechanical seals—we offer almost every standard, norm, and DIN mechanical seal at attractive prices. In addition, we offer many OEM mechanical seals from a wide range of pump manufacturers.
Cartridge-mounted mechanical seals:
Cartridge-mounted mechanical seals are our specialty. If these do not meet the standard requirements for your specific application/installation space, we can quickly and cost-effectively customize them for you.
Special seals/mechanical seals according to customer requirements:
We are also happy to manufacture mechanical seals according to customer requirements. In line with our philosophy, we first take a close look at your sealing requirements. We then select the right materials based on your needs to ensure a robust and durable design in conjunction with our design.
