Core drilling device - Holding mechanism for removing sediments from water bottoms

The holding mechanism is usable with sediment core devices using replaceable acrylic tubes, which do not have steel-tubed liner housings. The patented product and the respective process connect the pipe firmly and tightly to the holder. The proposed combination of holder and seal results in a simple handling and reduces the susceptibility to errors of sediment core devices.

Unique selling points:

  • Can be used for all pipes, regardless of manufacturer and material
  • cost-effective
  • easy to handle
  • insensitive to dirt
  • easy and quick to change
  • Easy to obtain parts - no special dimensions, threads or attachments

Users / Customers: Suitable for industrial customers with (intended) presence in the relevant markets. Can also be used for self-developing users.

Stage of development: The device is fully developed and ready for use. Due to limited manufacturing capacity, an industrial partner is being sought for further marketing.

Offer: Patent transfer or licensing to interested companies.
