The Pratissoli Pumps KT28ASPF high-pressure water pump, distributed by Dynablast, is ideal for hydroexcavating. It offers 18.4 gpm, 2,900 psi, 1,450 rpm, and a 35 hp power end. It is available with a T13 female spline shaft and SAE B flange. It is a self-lubricating pump with no oilers required and has two bore-size ceramic for better protection from thermal shock. A symmetrical power end allows for the pump shaft to be easily reversed, and its crankcase with fins creates cooler operation. It also has a tapered roller bearing that helps improve lateral loading and an oversized inlet and softer inlet valve springs for tank feed applications. The wet end can be serviced without entering the crankcase. Ideal setup would be to reduce pump speed by 50 percent, which will reduce water flow to 9.2 gpm, and then to choose a dig nozzle and return a few gallons per minute back to the water tank. 905-867-4642 www.dynablast.ca
