Equipment

Akkerman Inc.

Akkerman manufactures project‐specific shaft seals and pipe clamps to complement our MTBM system on projects presenting high‐water head.

Shaft Seals contain a hydraulically adjustable pipe brake to control the pushback movement of the pipe string. Redundant rubber seals are efficiently spaced around the shaft seal to deter inflow into the shaft. Shaft seals are positioned on the entrance and exit shaft walls at project line and grade.

A Pipe Clamp, sometimes called a pipe brake, is used to contend with buoyant forces when installing an MTBM within a water body or on any projects with high water pressures. The pipe clamp’s adjustable chocker plates ensure that the Shaft Seal rubber does not invert with a high axial holding capacity.

MTBM Shaft Seals and Pipe Clamps are custom‐fabricated to match the outside diameter of the project pipe. Contact our knowledgeable sales team for more information on these products.
