Use this updated sewer jetter for sewer blockages and other tasks (with related video)
The Vactor RamJet 850 Series truck jetter features several updates and improvements. Sewer cleaning professionals have used the model for more than 40 years to clear sewer blockages, assist in preventive line maintenance and other tasks. Vactor Manufacturing is the producer of the product.
The updated model features the manufacturer’s Park-N-Clean technology, a system that allows the operator to park near the manhole and, with minimal setup time, start cleaning within minutes. Simple controls located at the hose reel or on the optional remote allow the operator to manage all machine functions. 
The Vactor water system with multi-flow allows the operator to set a lower desired flow at a lower rpm, without diverting high-pressure water back to the water tank. The end result is improved fuel efficiency and reduced wear on components.
An integral aluminum rear shroud with heavy-duty, see-through Lexan windows is available. Large service access doors on both sides of the shroud enable easy greasing, maintenance and service. The rear shroud keeps the hose and components warm and protected. This is especially helpful for crews working in extremely cold conditions.
The unit’s water pump is located at the side of the unit below the top of the chassis frame, allowing 100 percent of the water to gravity feed the pump to optimize water pump efficiency and eliminate the potential for water pump damage due to cavitation. The pump location provides complete access for operation and maintenance from ground level.
Designed specifically to clean sewers, the manufacturer’s JetRodder water pump uses a slow pump stroke to deliver maximum, continuous flow and pressure with minimal wear. This jackhammer action provides optimal cleaning capability. Since the pump is hydraulic and uses a single piston, no components or belts prone to breakdown are required.
The RamJet 850 comes standard with a certified flow of 0 to 80 GPM at a variable pressure up to 2,500 psi at the hose reel for the flexibility to clean any size line.
The unit’s standard front-hose reel has a capacity of 800 feet of 1-inch hose. The front-hose reel can telescope up to 15 inches forward and rotate up to 270 degrees, providing easy alignment with manholes.
The standard rear-hose reel has a capacity of 700 feet of 1-inch hose. The reel can rotate a total of 180 degrees – 90 degrees to curb side and 90 degrees to street side.
The RamJet 850 features the manufacturer’s Park-N-Clean technology. It is a system that allows the operator to park near the manhole and, with minimal setup time, start cleaning within minutes. Simple controls located at the hose reel or on the optional remote allow the operator to manage all machine functions.
Buyers can choose from front- or rear-hose reel locations. An optional JetRodder water pump-heated cabinet is also available. The cabinet keeps the pump and plumbing covered and protected at all times.
