The CM-8000 is Maniar's highest-capacity combination sewer cleaner, an 8,000-liter unit mounted on a 16-ton GVW chassis, combining high-pressure jetting with vacuum suction in one unit — a 4,000-liter fresh water tank for jetting and a 4,000-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-8000's 260 LPM / 150 bar triplex plunger pump, driven by a full-torque split-shaft PTO, forces water through a 25mm 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 540 cum/hr vacuum pump — the highest flow in the CM-series — 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 4" 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-8000's 540 cum/hr vacuum pump — the highest flow in the CM-series — pairs with a wider 4" (100mm) suction hose, compared to the 3" (75mm) hose used on the smaller CM-4000 and CM-6000 at 390 cum/hr.
The collection body's discharge system can be configured to match how you unload at the disposal site:

From about 750/1000mm up to 1500mm (30-60 inches) in diameter on the jetting side, using its 260 LPM / 150 bar jetting pump and 60m hose — the largest capacity in the CM-series.
A 4" (100mm) hose, matched to its 540 cum/hr vacuum pump flow — the highest suction flow in the CM-series.
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.
The CM-8000 carries roughly double the jetting flow (260 LPM vs. 137 LPM) and higher suction flow (540 cum/hr vs. 390 cum/hr), with correspondingly larger jetting and suction hoses, on a larger 4,000L / 4,000L tank split.
