13. LIQUID ASPHALT OIL PUMP
A hydraulically driven, 1 1/2" self priming, variable speed, reversible, rotary gear pump with relief valve. Operating at 20 GPM at 1200 RPM, 100 PSI. The pump will circulate the emulsion oil to prevent separation and to crush any lumps that may form and cause clogging of the spray tip. Air injection systems do not have this capability.
14. PAVEMENT BREAKER
We offer optional; Stanley BR45, 67 and 87 Pavement Breakers, complete with asphalt cutter, tamper and detachable shank with lockable transporting bracket.
