Drainage of the underground tunnel heading with the aid of submersible pumps.
Use of submersible pumps of the KTV series which can reliably ensure drainage in 24-hour snore mode during the heading work.
Thanks to their special properties including their internal rotating mechanical seal and upstream shaft protection sleeve with seal, the Tsurumi pumps can be operated in 24-hour snore mode.
