SC Hydraulic Engineering L6 High Volume Liquid Pump

SC Hydraulic Engineering L6 High Volume 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.

General Product Information

HIGH FLOW CAPACITY
DOUBLE ACTING, SINGLE STAGE
COMPATIBLE WITH MOST FLUIDS
STAINLESS STEEL WETTED PARTS
AIR OPERATED – NO ELECTRICITY NEEDED
THREE DIFFERENT PRESSURE RATIOS UP TO 11,200 PSI
DIMENSIONALLY INTERCHANGEABLE WITH MOST COMPETITIVE MODEL PUMPS

The SC L6 Series pump has a 6″ diameter air cylinder with stainless steel wetted parts. This double acting pump is capable of hydraulic pressures up to 11,200-psi and is available in three pressure ratios: 40:1, 60:1 and 100:1.

This pump is ideal for high flow at relatively high pressure applications. Nominal outlet flow ranges between 2-gpm to 1-gpm depending on outlet pressure and pump model. Maximum air consumption is approximately 200-SCFM at free flow (zero output pressure).

SC Hydraulic Engineering L6 High Volume Liquid Pump

It is designed to operate with air drive pressures between 15-psi and 100-psi under normal conditions and is dimensionally interchangeable with competitive model pumps. Typical applications include choke control operation, hydrostatic testing and press applications.

Modification

Remote Pilot : This option provides a 1/8″ NPT female port for remotely controlling the start/stop of the pump by connecting an external air signal to actuate the air cycling valve. This modification is built in as standard and no special number is needed when ordering.

M014 – Counter Port : This option provides a 5/8-18-UNF thread port on the air motor section of the pump for installing a mechanical cycle counter.
