LIQUID PUMPS

HOW THE PUMP WORKS Hydraulics International, Inc. (HII) air driven liquid pumps operate on the principle of differential working areas. An air piston drives a smaller diameter plunger or piston to provide a pressure ratio. The pressure ratio is the method of determining maximum outlet pressure available. Hydraulics International model numbers reflect the nominal pressure ratio of the pumps. Hydraulics International liquid pumps operate at a drive air pressure of 12-150 psi (0.8-10 Bar) and will cycle automatically when compressed air is first applied to the drive. It will start cycling at its...

HYDROSTATIC TESTING: Any component that is made to hold liquid or gas pressure needs to be carefully tested after manufacture or repair to verify its integrity, and/or to calibrate it. H.I.I. air driven pumps can simplify this requirement in a broad range of industries. CLAMPING-PRESSING-RELEASING: Hydraulic cylinders or rams that are required to maintain an output force without movement for long periods need a hydraulic pump that can maintain output pressure at zero flow for a long periods with no heat being generated. H.I.I. air driven pumps will do this over virtually any pressure range. VALVE...

PERFORMANCE CURVES These curves predict the performance of each model using drive pressures shown 150/95/75/50-psi, 10/7/5/3-Bar (interpolate for other pressures). Maximum flow points presume 1/4” I.D. drive line minimum to 3L Series; 1/2” I.D. minimum to 5L Series; And 3/4” I.D. minimum to 7L Series. Note: Limited drive flow does not inhibit maximum outlet pressure capacity. AIR DRIVE FLOW (DOTTED CURVES) NOTES: 1 Shaded area exceeds rated pressure.

“ B” Bottom Inlet. See dimensional data pg.6 and selection table pg. 4. This modification applies only to model item numbers 10 through 17 and 20 through 27. It is not available for item 28 or 29. It is standard on items 1-9, 18, 19, and 30-35 (which are not available with side inlet). “ D” Distance Piece. All series. Provides vented, dual seal protection where leakage or fumes from pumped fluid could attack the air drive section with only the single seal. Specify by adding -“D” after model number, e.g. Model 5L-SS-30-D. Double distance piece also available to protect air drive from some high...
