Thru-shaft Motor
The hydraulic powered thru-shaft motor rotates
the spray bar on the blasting head assembly. The
center of the rotating shaft is drilled to allow high
pressure water to pass through the shaft to the
spray bar. A specially designed swivel seal and
brass backup ring create a water tight, high pres-
sure seal at the connection of the high pressure
hose to the thru-shaft. The hose is secured to the
rotating shaft housing by the swivel nut.
The swivel nut is hand tightened only. If the
nut becomes loose, the hose will wobble and dam-
age the swivel seal. Additionally, if the swivel nut
is overtightened by using a pipe wrench or pliers,
the swivel seal will be damaged. The swivel nut

must be checked daily to ensure it is tight and
that the swivel seal is not leaking. Any water drip-
ping from the weep holes just below the swivel
nut while the system is pressurized indicates the
seal is leaking and must be replaced. Operating
the blasting head with a leaking swivel seal will
cause complete failure of the seal, stopping blast-
ing operations.
The RPM of the thru-shaft motor is controlled by
the HEAD ROTATION speed dial on the control
panel. A speed sensor on the thru-shaft motor
housing continuously monitors the RPM of the
thru-shaft/spray bar and displays the speed on
the digital HEAD ROTATION speed gauge in the
panel. During blasting operations, the operator
can monitor the RPM of the spray bar and make
adjustments as necessary.
