DESIGNER AND MANUFACTURER OF HYDRAULIC AND PNEUMATIC EQUIPMENT SC HYDRAULIC ENGINEERING CORPORATION

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...

AIR DRIVEN GAS BOOSTERS SC air driven gas boosters are self-contained units, using a cycling spool and pilot valve to provide automatic reciprocating action when air or gas is supplied to the air drive inlet. The drive consists of a large piston and valve assembly directly connected to a hydrocarbon-free pumping piston with self lubricating seals cycling in a stainless barrel that has an integral check valve. SC gas boosters are suitable for other applications such as bottle filling from nitrogen generators and dewars, hydrogas suspension systems, automotive air gas storage systems,...

GBD GBD-5 Single Stage-Double Acting Booster StageThis gas booster is a modified version of our popular ABD air booster. It is used to boost gas pressures up to 1,500 psig. The booster is able to move large volumes of gas efficiently when lower pressures are suitable. For convenience, the graph illustrates various inlet gas supplies with matching air drive pressures. 9.07" 17.38" 3/4" NPT DRIVE INLET Maximum Rated Gas Supply (Ps) Maximum Rated Gas Outlet (Po) A Inlet Port B Outlet Port Static Outlet Stall Pressure Maximum Compression Ratio Displacement Per Stroke (in3 per cycle) Min.
