This synthetic is the latest innovation in Monsanto's internationally accepted and growing line of fire-resistant hydraulic fluids and lubricants. In 1951 Pydraul hydraulic fluids first began work ing to protect hydraulic operations from fire. Now, well over a decade later, the seven Pydraul fluids have performed millions of machine hours of service without contributing to a single fire ... not even when sprayed from ruptured highpressure hydraulic lines onto white-hot metal. And besides fire-resistance, the Pydraul fluids have always offered . . . ... lubrication as good as premium grade oils . .. freedom from corrosive action and foam . . . ease of maintenance .. . and permanence -- they don't "wear out" Where does new Pydraul 312 fit into this well established picture? Pydraul 312 hydraulic fluid is a unique marriage of synthetic fluids with specially chosen petroleum fractions. The result is a fire-resistant hydraulic fluid that matches or excells the properties of existing hydraulic fluids -- including synthetics premium grade petroleum oils, and water-contain ing fluids -- but sells in the same price range as water/glycol fluids. They offer up to k0% eatings over other water-free, fire-resistant hydraulic fluids. HONS 074210 Inspection Properties ... Viscosity. SSU ( 40F Viscosity. SSU <w I00F Viscosity.

The corrosion and oxidation stability properties of Pydmul 312 arc equal to those of the best petroleum hydraulic fluids. Pydraul 312 will not rust or corrode any metal in a hydraulic system even when over-heated to 250F. In the ASTM D-665 Baal Teat Pydraul 312 showed no rust at all, and in use Pydraul 312 docs not lose its anti-rust properties. Good hydrolytic stability is a basic characteristic of Pydraul 312. If water somehow enters your hydraulic system, Pydraul 812 won't hydrolyze to foam acidic or corrosive products.

Temp F 940 High Pressure Spray Test (AMS-3150C and Federal Test Method STD791). Test fluid sprayed at 1000 psi through orifice, passing through flame of oxyacetylene torch, 6000F. Intermittent flashing but self-extinguishing. Low Pressure Spray Test (AMS-3150C). Test fluid sprayed at low pressure over ignited, oil-soaked rags to determine degree of increase in flame intensity. Slight increase in flame intensity, Hot Manifold Test (Federal Test Method STD791) Test fluid dripped on tube at I300*F. Intermittent flashing but does not propogate to pan below. Molten Metal Ignition Test. Test fluid exposed to the surface of aluminum alloy at 1200F to test for spontaneous ignition. Does not ignite spontaneousty. Flashes intermittently with ignition source. Your Monsanto representatives will be glad to show you color motion pictures of the performance of Pydraul 312 in these tests. To test fire-resistance under working conditions, Pydraul 312 was sprayed on actual ignition sources in operating plants. In no case was a fire carried from the immediate source of ignition. In one plant, a line rupture on a die-casting machine sprayed Pydraul 312 onto molten aluminum in a holding furnace and over the surrounding area. Flame was confined to the furnace, no plant per sonnel were injured, and there was no fire damage. Performance Properties ... Pydraul 312 has good viscosity and viscositytemperature (V I ) properties. These properties are permanent. Pydraul 312 will not shear mechanically to degrade viscosity. The following chart shows viscosity of Pydraul 312 before a Vickers Hydraulic Pump Test... and practically the same viscosity after the test. MOMS 074212 # # UMnMIUH.

Converting to Pydraul 312 hydraulic fluid is easy. Virtually every type of equipment that uses fireresistant hydraulic fluid has been converted to Pydraul fluids. Equipment manufacturers are, therefore, experienced in Pydraul fluid conversions and should be consulted. ' 3. Open or remove and drain valves. Replace gaskets, packings, and seals with those com patible with Pydraul 312. It is particularly important to change dynamic seals. Static seals do not necessarily have to be changed if there is no objection to replacing them each time If changing seals is necessary, equipment manu hydraulic components arc serviced. facturers can tell you what seals to change, and most even carry a supply of correct seals. Labo ratory tests show that Viton and silicone seals are best for Pydraul 312. 4. Remove pumps, accumulators, and cylinders, if necessary, for draining. Replace packings, seals, gaskets, and bladders with those com patible with Pydraul 312. To replace other Pydraul fluids with Pydraul 312 where compatible seals arc in the system, it is only necessary to add Pydraul 312 as make-up fluid. It is not necessary to drain or clean. When you convert from petroleum oils, non-Pydraul synthetic fluids, water/glycol fluids, or water-in 5. Check component functions before the system is closed and fluid is added. 6.

These steps conform to National Fluid Power Association Standards.

A* with all specialized industrial fluids, certain precautions are advisable when handling Pvdrnul 812. No problems will arise when Pydraul 312 is used as recommended. Avoid repealed or continuous skin contact. Re pented or prolonged contact can lead to drying and skin "chapping". Where prolonged skin con tact cannot be avoided, gloves should be worn. At room temperature there is no significant vapor inhalation hazard from Pydraul 312; however, in halation of vapors produced when the fluid is at high tem|ieraturea should be prevented. Single 6-hour exposures to an atmosphere saturated with vapors at ambient temperatures produced only mild discomfort in experimental animals and they survived the 10-day subsequent observation period without ill elTect. Although eye irritation studies using Pydraul 312 at full strength indicate Pydraul 312 is a inild irritant, there is no evidence to show Pydraul 312 causes permanent damage to eye tissue. If Pydraul 312 is splashed or sprayed into the eyes, eyes should be thoroughly flushed with water and the workman referred to a physician. To relieve irri tation, physicians have used 1% tetracaine solu tions, as well as ophthalmic cortisone acetate solution. Pydraul 312 hydraulic fluid can be stored at sub zero temperatures without fluid damage. Before using, simply allow the fluid to wnrm to 20 -- 80*K. Drums stored outside should be sealed tightly and placed in a horizontal position to keep out moisture. f DISTRICT SALES OFFICES ALL DIVISIONS ATLANTA, GEORGIA 30326 Lanox Towns Cost 3400 Peachtree Hd.
