THE KR SERIES OF AIR OPERATED FLUID PUMPS AND HYDRAULIC POWER PACKS IS AVAILABLE IN 5 MODELS WITH FLUID-TO-AIR
PRESSURE RATIOS FROM 5 TO 80:1
ALL MODELS EMPLOY THE SAME AIR DRIVE WITH ONLY THE FLUID END VARYING IN SIZE TO PRODUCE THE DIFFERENT PRESSURE
INTENSIFICATION RATIOS.

Technical Data
Maximum air consumption
- approx. 20 scfm at 500 cycles per min.
Maximum hydraulic power - .37 kW (0.5 hp)
Maximum cycle speed - 500 cycles per min (intermittent duty). For continuos duty maximum cycle speed should
be reduced to approx. 50-60 cycles per minute. Applications involving continuous pumping should be referred to Heypac.
Maximum air pressure - 125 psi (8.5 BAR)
Minimum air pressure - 20 psi (1.4 BAR)
Fluid temperature range - 23 deg F to 158 deg F
Air Inlet - 3/8 NPT
Air Exhausts ( 2 per pump ) - G 3/8"
