PULLERS: HYDRAULIC POWER UNITS

Pump and Ram Set Components
Features of two-stage hydraulic pumps:
• Two stage design will advance 20–50 ton rams in the low pressure CG420-1A
stage in less than 1/3 the strokes required on other models
• CG520 Ram extends in 60–70 strokes CG650
• CG420 Ram extends in 17–19 strokes
• When high pressure is required, the low-pressure stage automatically
kicks out to leave the high-pressure stage to do the work CG720 GENERAL
