LUMBERJACK®LJ050 is the smallest turbine cutter in the LUMBERJACK® series. LJ050 is the most powerful small cutter on the market. LJ050 cover pipe sizes from 3” up to 6” and is supplied complete in a kit. LJ050 can be supplied with ½” or ¾” hose connection. The cutter is propelled through the pipe with a thruster, that has 3 ceramic inserts that are jetted for the unit it will be used on. This give the cutter the maximum efficiency of the water being supplied.
The cutter can operate effectively with as low water flow rate of 10 US GPM and can handle pressures up to 3500 PSI.
Rotation speed of cutter is approximately 20,000 rpm in the pipe and the material to be removed through cutting links reinforced with hardox. If material to be removed is in center of the pipe the harden front knife, placed on top of the turbine engine, is used to open a path allowing the cutting links to do the rest of the work.
Never operate the cutter without a centralizing sled. You must size the Lumberjack according to the size of the host pipe, this included using the correct chain that corresponds to the size of the sled and pipe. Using the incorrect size sled or chain can result in damage to the host pipe and possibly result in getting the cutter stuck in the pipe.
As a special feature for the LUMBERJACK LJ050® are brush sleds supplied as spare. The brush sled let the cutter pass a 45 or 90-degree bend, still being centralized once cutter enter the straight line. Never put water pressure to cutter passing the bend. Push the cutter through the bend by hand and first when cutter has entered the straight line, the cutting operation can start.
There is no daily maintenance required for the Lumberjack 050 series. We only recommend you rinse it off when use is complete for the day.
DO NOT OIL THE CUTTER!
The unit comes with grease filled sealed bearing and are water cooled. Over time the bearing will require replacement. This can be easily accomplished by your operator or returned to NozzTeq.
The lifespan of the LJ050 is between 7 – 15 years.
