The CM-6000 is a 6,000-liter combination sewer cleaner (also called a combo truck or jet vac truck) mounted on an 11-ton GVW chassis, combining high-pressure jetting with vacuum suction in one unit — a 3,000-liter fresh water tank for jetting and a 3,000-liter sludge tank for suction, so one machine and crew can jet a line and vacuum out what it dislodges in the same pass.

Jetting side: the CM-6000's 137 LPM / 140 bar triplex plunger pump, driven by a full-torque split-shaft PTO, forces water through a 3/4" x 60m hose and a self-propelled nozzle that pulls itself forward through the line, breaking up blockages and flushing debris out ahead of it.
Suction side: a 390 cum/hr vacuum pump generates high vacuum in the sludge tank to siphon effluent, liquids, and settled sludge out of sewer lines, septic tanks, lift stations, and catch basins through a 3" x 15m hose. A sludge stirring arrangement uses high-velocity air to convert solid silt into a liquid or semi-liquid slurry the pump can draw up, and a blow-back system can then discharge just the water content of the tank under pressure, so the truck carries away the sludge without hauling unwanted water weight.
Every CM-series combination sewer cleaner ships standard with two nozzle types:
Additional nozzle types can be supplied to match specific jetting jobs, including:
The suction hose is sized to match the vacuum pump's flow, so the hose itself doesn't choke the pump. The CM-6000's 390 cum/hr vacuum pump pairs with a 3" (75mm) suction hose; the higher-flow CM-8000, at 540 cum/hr, needs a wider 4" (100mm) hose to move that volume without excessive restriction.
The collection body's discharge system can be configured to match how you unload at the disposal site:

From about 450 to 500mm (18-20 inches) in diameter on the jetting side, using its 137 LPM / 140 bar jetting pump and 60m hose.
A 3" (75mm) hose, matched to its 390 cum/hr vacuum pump flow.
The standard configuration is hydraulic tilting combined with hydraulic door opening. Hydraulic door locking, a derrick arm, or a hydraulically operated suction hose reel can also be specified.
Both share the same jetting and suction specs; the CM-6000 carries a larger 3,000L / 3,000L tank split (vs. 2,000L / 2,000L) on an 11-ton GVW chassis, for higher-volume routes between dump trips.
