Fecal cistern 12 m³, hook-lift
A complete fecal cistern that any suitable hook-lift truck can carry. It sucks out septic tanks and pits by vacuum, carries the load and discharges it. A separate water chamber and a high-pressure pump with hose reels clean sewers, shafts and hard surfaces. Compressor and pump have their own drive, so the truck can drop the body on site and leave.

Request an offerTwo chambers, one tank
The cylindrical pressure tank holds 12 m³ in two chambers: 9,000 l for sludge and 3,000 l of clean water for flushing. The sludge chamber works from −0.8 bar vacuum to 0.7 bar pressure, so it fills by suction and empties under pressure or by gravity. The tank is built to EN 13445 and CE marked.
Own drive
The vacuum compressor and the high-pressure pump run on the unit's own drive, housed behind the hook frame. No truck PTO is needed, and the cistern keeps working after the truck has gone.
Equipment
Suction hose stowed on top, hose reels for flushing, a work platform with railing and a ladder, separators on the vacuum line, and aluminium tread-plate boxes for tools and couplings.
