SC Hydraulic Engineering 80-5 Intensifiers

Product Information

SC Hydraulic Engineering 80-5 Intensifiers is a leading manufacturer and designer of an ever-growing line of high-pressure, air-driven liquid pumps, as well as air and gas boosters which are being used in a variety of industries and applications.

  • High Output Capacity
  • Guaranteed Performance
  • Simple Operation Principle
  • Designed For Easy Maintenance
  • Wide Range Of Operating Pressures

SC Hydraulic Engineering 80-5 Intensifiers operate on the same principle as our air-operated liquid pumps with one distinctive difference – the air motor is modified so that it operates as a double-acting cylinder. Instead of automatically reciprocating until the stall pressure is reached, the 80 Series Intensifiers require an external four-way air valve to operate the unit.

The end caps have 1/4″ NPT air supply port connections and the unit can be supplied with a position indicator rod at the top of the intensifier if required. All ratios and options available on the intensifiers are the same as on our D5 and D6 Series pumps. The units can be mounted in any position however upright is preferred. The air cylinder does not require lubrication.

SC Hydraulic Engineering 80-5 Intensifiers Application

  • Static and burst testing
  • Hydraulic Press operation
  • Clamping
  • Pressing
  • Piercing
  • Blanking
  • Staking
  • Flow testing requiring relatively low flows at high pressures
  • Applications requiring extreme intermittent pressure and velocity commonly associated with water blasting and jetting.

(1) Coned and threaded high pressure connection for 1/4″ O.D. tubing.
(2) Maximum allowed working pressure for oxygen service boosters: 5,000 psi max.
(3) Maximum allowed working pressure for hydrogen service boosters: 6,000 psi max.
(4) Oxygen & hydrogen service boosters are not available on all models. Contact the factory for more information.

Refer to corresponding gas booster performance curve for operating pressures. Maximum material-rated outlet pressures can be reached under special operating conditions. Do not use air drive and/or gas supply pressures that equate to higher outlet pressures than those “maximum material rated outlet pressures” shown on table. Refer to Static Outlet Stall Pressure formula shown on table (for example, for gas booster model GBD-30 the formula is: Static Outlet Stall Pressure = 30*Pa+Ps). Maximum recommended air drive operating pressure: 100-psi. Maximum-rated air drive pressure: 150 psi (only for static outlet stall pressure).

A Models: These models utilize dual seals in the hydraulic assembly with a bleed-off between the seals and to the 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.

C Models:The “C” Models utilize PTFE chevron packing in the hydraulic assembly for ultimate performance when another packing material is not compatible with the fluid used or because of extreme temperature conditions. The “A” modification is included on all “C” models and the check valves have PTFE o-rings.

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.
