Tenbusch Lubricant System on Job


Lubricants are required in underground construction applications to reduce friction and lower jacking forces for pipe, casing, and box-culvert installation.

We design and manufacture systems for mixing and pumping underground lubricants such as bentonite and/or polymer solutions. Our pre-configured and custom lubrication systems are designed for underground construction applications such as:

  • Tunneling and pipe-jacking,
  • Horizontal earth boring,
  • Directional drilling and boring,
  • Auger boring,
  • Well and shaft drilling.

Our lubricant systems are very efficient and effective - the mixing and pumping processes have been optimized for the specific conditions encountered in underground construction. Standard features of our lubricant systems are as follows:

  • High pressure fluid circuit for long transmission lines and to penetrate annular spaces surrounding pipe,
  • Low pressure fluid circuit for mixing and transport,
  • Controls to match flows to work requirements.
  • High-capacity reservoirs appropriate for underground applications,

Additional options available for your lubricant unit:

  • Dual reservoir design for simultaneous mixing and pumping,
  • Centrifugal mixing and piston delivery pumps,
  • Hydraulic pump drive,
  • Ergonomic valving for lubricant re-circulation,
  • Continuous re-circulation and delivery flow adjustment,
  • Integral power source - combustion engine or electric motor.

We work hard at Tenbusch to provide you with high-quality lubricant systems that are efficient, productive, and cost effective.

Tenbusch Colloidal Mixing Unit

Specific "colloidal" mixing units are available for effective mixing of the following materials:

  • Bentonite,
  • Polymer solutions,
  • Grout.

Tenbusch colloid mixers employ a "paddle wheel" beater to enable thorough mixing of the mixed material.
