Industries & Applications Liquids Pumped (2) Features

Standard Iron

Petroleum Products • Machine Manufacturing • Machine Tools • Crane • Speed Reducers • Hydraulic Equipment • Lubrication Systems • Diesel Engines • Food Processing • Restaurant Equipment • Misc. Chemical, Glue & Ink • Soap and Detergent Products • Drug • Building & Highway Contractors • Paper Products • Automotive • Shipbuilding • Beverage • Aircraft • Mining • Misc. Manufacturers • Primary Metal • Electrical Equipment & Supplies.
Fuel oils*, hydrocarbons, lube oils, syrups, diesel fuel, coolants, cooking oils*, wire drawing compounds, hydraulic fluids, quench oils, heat transfer oils*, tar*, ethylene glycol, varnish*, wax*, vegetable oils, detergents, lacquer*, soaps, calibration fluids, glycerin, adhesives*, molasses, transformer oil, ammonia, anhydrous ammonia.
Normal use: Cast iron casing and cover components: steel shaft and pinion gear; high tensile iron rotor; self-lubricating iron bearings; Buna-N lip seals.

Hardened Iron

Building & Highway Contractors • Textile Mill Products • Misc. Converted Paper Products • Printing and Publishing • Chemical • Plastics and Synthetics • Drugs & Pharmaceuticals • Paint & Allied Products (Mfg. of paints, varnishes, lacquers & enamels) • Misc. Chemical, Glue & Ink • Soaps & Cleaners • Machine Manufacturing • Beverage.
Acetone*, turpentine*, alcohols (most grades), paints*, asphalt*, jet fuels, asphalt emulsions*, EDM oils, brines*, kerosene, caustics (sodium hydroxide)*, methyl ethyl ketone*, benzene*, latex*, methanol, gasoline, mineral spirits (naphthas), heptane, solvents*, hexane, styrene*, printer's ink*, xylene*, isopropyl acetate*, ethylene acetate*, paper coatings*, toluene*.
Wear resistant: (1) All metal parts in contact with the liquid are hardened by a superior new nitriding process that makes metals tougher. Seals and bearings are the same as standard iron construction.

Corrosion Resistant

Food processing • Chemical • Pharmaceutical • Textile • Plastic • Paint • Tanning • Soap • Rubber • Photographic • Synthetic fibre • Plating.
Acids–concentrated sulfuric, nitric, diluted phosphoric, chromic aqueous, citric aqueous, acetic. Essential oils, syrups, chemicals, vegetable oils, ammonium sulphate, corrosive wax, brines, sodium bicarbonate, sodium hydroxide, plating solutions.
Note: Please see HP500 - FF Pump brochure for information on stainless steel design.
*Although standard or Hatrided iron construction is used for these liquids, we normally recommend alternate seals or bearings due to temperature extremes or liquid compatibility. See listing of alternative seals and bearings on page three.
(1) Normally recommended for abrasive applications or for liquid with little or no lubricity.
(2) Liquids listed above do not include all of those that Haight pumps have been used for, rather, it is a selection of liquids taken from various applications where such pumps are normally used.
