The Water Technology Division of Putzmeister America has added the PWT 170 Series water-jetting unit to its product offering. The unit uses a 170-horsepower John Deere four-cylinder diesel engine that drives a “triplex” plunger pump that produces flow rates and pressures from 18.2 gpm at 10,000 psi, to 4.8 gpm at 40,000 psi.
