SC Hydraulic Engineering 10-4 Liquid Pump
SC Hydraulic Engineering 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.
SC Hydraulic Engineering 10-4 Liquid Pump 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.
Product Information
GUARANTEED PERFORMANCE
MULTIPLE OUTPUT CAPACITIES
SIMPLE OPERATION PRINCIPLE
DESIGNED FOR EASY MAINTENANCE
WIDE RANGE OF OPERATING PRESSURES
10-4 Series pumps have a 4″ diameter air piston and a 1 1/4″ stroke. Nine models are available with pressures up to 29,500 psig.
When operating from 0 to rated hydraulic pressure, air consumption will be approximately 14 scfm of free air at 100 psi output. At lower air pressures and higher hydraulic pressures, air consumption will be reduced proportionately to flow rates indicated.
Application
Piercing
Blanking
Pressing
Clamping
Metal forming
Static and burst testing
Hydraulic Press operation
Flow testing requiring relatively low flows at high pressures
Applications requiring extreme intermittent pressure and velocity commonly associated with water blasting and jetting.

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.
