DESIGNER AND MANUFACTURER OF HYDRAULIC AND PNEUMATIC EQUIPMENT SC HYDRAULIC ENGINEERING CORPORATION L3 SERIES AIR OPERATED LIQUID LIQUID PUMPS

A “High Pressure” History… An innovator and pioneer in the field of hydraulic engineering, SC Hydraulic has been manufacturing air-driven liquid pumps for more than a half of a century. Founded in 1953 by Bob Vedder and Willie Mohler, the company started with only a few core products. Basically air-driven liquid pumps. Today, SC Hydraulics' product line has expanded to include an extensive collection of air and gas boosters, power units, systems and selected high-pressure valves. The product line remained stable through the 1980’s seeing successful operation in an ever-increasing number of installations...

L3 SERIES COMPACT PUMPS • EASY TO INSTALL & OPERATE SC air driven compact liquid pumps operate on the principal of differential areas. An air piston drives a smaller diameter hydraulic plunger to provide a pressure ratio. The pressure ratio determines the maximum outlet pressure. SC compact liquid pumps cycle automatically. Compatible with all hydraulic fluids, plain water, distilled and di-ionized water, solvents, mild chemicals and liquefied CO2. When compressed air is first applied to the pump, it will cycle at its maximum speed producing maximum flow. At this stage, the pump is acting as...
