Combination water jet cleaning / sewer cleaning - Water and Wastewater - Sludge Management

We have numerous requests each year for high-pressure sewer cleaning machines. We are in the unique position to be able to offer “combination” water blast/sewer cleaning units that provide more versatility than a standard 2,000 psi or 3,000 psi (140 to 206 bar) sewer cleaner.


In one particular case, the owner of a company had a small 2,000 psi (140 bar) unit and was interested in a much larger unit so he could clean city sewer lines as well as do work in the industrial market. A typical commercial sewer jet truck handles 50 to 60 gpm (190 to 230 lpm) at 2,500 to 3,000 psi (172 to 206 bar) and carries about 1,000 gallons (3785 liters) of water. He felt he could use his 1,600-gallon (6057 liters) tank-truck for the water supply and tow the NLB trailer-mounted water blaster.

The Model 10200D, when equipped with 1-1/2' plungers, is ideal for meeting the 50 gpm (190 lpm) requirements for sewer cleaning. Coupled with the 500 ft. (152 m) capacity hydraulic or air powered hose reel, municipal work can also be done. With an easy to change plunger conversion kit using 1-1/4' plungers, you have a high-pressure pump unit, which can be used in almost any industrial cleaning application at 10,000 psi (700 bar) and 34 gpm (130 lpm).
