SC Hydraulic Engineering 80-6 Series Intensifiers

SC air operated hydraulic pumps operate on the simple but efficient principle of pressure intensification through the use of differential areas. Fulfilling Boyle’s Law, a larger air-driven piston delivers pressure to a proportionally lesser diameter hydraulic piston, providing fluid flow at relatively higher pressures.

High output capacity and outstanding performance provided at very low cost.

All SC Hydraulic pumps will give years of low cost, trouble free service when properly installed and maintained to manufacturer’s instruction.

Wide range of operating pressures is provided by all models. For example, the D5000B55 operates efficiently when delivering from 400 to 5800 psi (see D5 Series specifications).

Due to a wide range of output capacities, only 100 psi air pressure is required for all models to attain maximum rate of flow (see performance charts for data).

Whenever an SC Hydraulic pump is idle, the pilot valve is designed to re-position the pump on the power stroke for the next cycle of operation.

The air piston actuating valve is precision fit to close tolerances for maximum efficiency and long service life.

Both pressure and volume of flow are easily and accurately controlled by a pressure regulator installed in the air supply line.

Pumps can operate with almost any type fluid service (specify when ordering).

Hydraulic cylinders are constructed from aluminum-bronze, stainless steel, or carbon steel.

Hydraulic pistons are constructed from stainless steel, hard chrome-plated.

Materials incorporated in the hydraulic assembly vary depending upon type of service and pump model.

Costly down time is reduced to a minimum when service is required. “D” Dry Lube Series pumps are packed at the factory with valve lubricant and may be operated without a lubricator in air supply. Hydraulic cylinder packing may be replaced without dismantling the air motor.

Three series available – choose from:

SC Hydraulic Engineering 80-6 Series 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.

Growing since 1953, we offer liquid pressures as high as 65,000 psig and can exceed 17,000 psig in gas pressures.

General Product Information

SC Hydraulic Engineering 80-6 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.

Performance Chart

Modification

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.

C Models : The “C” Models utilize PTFE chevron packing in the hydraulic assembly for ultimate performance when other 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.
