WEFTEC. The 4JSCM is a
more powerful, lighter
weight and more compact
4-in. pump that
handles solids up to 3 in.
With a flow capacity of
1,450 gpm and a shut
off head of 130 ft, this

TT Technologies
TT Technologies will be displaying the
Grundoburst static pipe bursting system at
WEFTEC 2007. The Grundoburst is ideal for
the trenchless replacement of water lines. The
system utilizes a specially
designed bladed
cutter head to
make bursting ductile
iron and steel pipe
possible. Patented
QuickLock bursting
rods are linked together, not threaded. This
saves time, prevents twisting and extends the
life of the cutter head over threaded bursting
rods. Models range in pullback force from
60,000 to 650,000 lbs. Grundoburst models
are designed for bursting 4- to 48-in. diameter
pipe. RS# 123
