Where to rent a grinding machine, lathe or test bench?


A high-quality machine rarely fits every application straight away. You often need special accessories or technical adaptations to ensure that everything runs smoothly. With our EFCO Rental Service, you can rent exactly the right machine for your project. You use modern technology and can see the quality for yourself without having to buy straight away. Renting gives you the freedom to react flexibly to changing requirements.

We offer you the rental of the following EFCO systems:
  • Grinding machine: For the precise machining of sealing surfaces on fittings and flanges
  • Lathe: Ideal for facing and internal turning directly on the component
  • Test bench: For safe pressure and function testing of fittings under real conditions

Whether for short-term or long-term use, you are on the safe side with our rental offer. This saves you costs and keeps you technically up to date at the same time.

Since the foundation in 1978, we have been working as a family business according to the philosophy of winning our customers as partners. Together, we thus solve the problems that arise when machining and testing the sealing surfaces and flanges of valves.
