SC Hydraulic Engineering Corporation

40 Series Power Units

General Product Information
- EASY TO INSTALL
  PRESSURES UP TO 65,000-PSI
  COMPACT AND LIGHTWEIGHT
  INCLUDES RETURN-TO-RESERVOIR LINE
  COMPONENTS INSTALLED ON A BASE PLATE
  AVAILABLE WITH ALL 10-SERIES PUMP MODELS
  INCORPORATES OPTIONAL TWO OR THREE GALLON RESERVOIR
  
  The 40 Series incorporates a larger base plate than the 30 Series to accommodate an optional two or three gallon reservoir.
  
  Light weight, easy to install. Only three connections are required; air, fluid supply, and work port.
  
  Two pressure ports, one equipped with shut-off or bleed valve, provide ease of control during operation. Valve connects to reservoir when so equipped.
  
  Air exhaust muffler provides for quiet operation, 3 1/2" dial liquid filled gauge standard on units up to 30,000 psi.
Applications

Modifications

A Models:These models utilize dual seals in the hydraulic assembly with a bleed-off between the seals to atmosphere, thus providing a visual indication of hydraulic seal leakage. Used where contamination of the air motor from the hydraulic fluid being pumped is objectionable.
B Models: The "B" models have a bottom inlet connection for convenient tank top installation or alternate mounting configuration.
H Models: The "H" Models utilize special packing in the hydraulic assembly for maximum performance where hydraulic fluid media is contaminated with foreign matter, thus providing for a much greater life expectancy from the hydraulic seals than with standard o-ring seals. The "A" modification is included on all "H" models and the check valves have PTFE o-rings.
K Models: This models utilize a special air piston in the air motor assembly which decreases the stroke of the pump, thus minimizing the internal forces and increasing air motor life. Used in applications exhibiting rapid pressure losses, such as burst testing.
R Models: The "R" Models are furnished with an isolator attachment which prevents the hydraulic piston retracting into the air motor during operation, thus providing for 100% non-contamination of the hydraulic assembly from the air motor. The isolator also acts as a heat barrier.
