#287H FLUSHING AGENT

Flushing Agent is a non-toxic, non-drying, anti-wear flushing and cleaning lubricant that can be used to clean and flush all types of gear boxes and hydraulic systems. Flushing agent provides the following performance benefits:

Non-corrosive

High solvency

Combustible—not flammable

Low viscosity for ease of mixing

Hygroscopic for removal of water

Flushing Agent is fully compatible with petroleum based lubricants such as USP White Mineral Oils, Technical White Oils, Paraffinic or Naphthenic based mineral oils and synthetic based fluids such as Polyalphaolefins (PAO), Synthetic Hydrocarbon based, Polyol Ester and Diester based fluids. Flushing Agent is also compatible with seals and elastomeric materials, paints and coatings which are known to be compatible with petroleum based lubricants.

Flushing Agent can be used along with the existing lubricant in order to clean and flush gear cases, hydraulic systems, and other types of equipment of carbon and varnish deposits, debris, sludge, dirt, etc, without teardown and dismantling of the equipment. This results less downtime and savings in labor costs.

While Flushing Agent has excellent cleaning and load carrying capabilities it should always be used along with the existing lubricant at the recommended treatment levels for flushing and cleansing.

Gear Box Cleaning Procedure

Clean the gear boxes in accordance with periodic maintenance schedules. Attention should be given to breather seals, sight glasses and fittings. It is recommended that water and moisture should be removed first from the gear boxes using the following procedure:

Open drain plug

Drain until milky fluid and/or water and sediment stops running out of the gear box.

Replace the drain plug.

Clean breather and sight glass.

Fill to the required level.

Change-Out Procedure

Drain approximately 10 to 20% by volume of the existing lubricant being used in the gear box.

Add a charge of 10 to 20% by volume of Flushing Agent to the existing lubricant one to five days prior to change-out. The percentage of Flushing Agent to use depends upon the severity of contamination.

After the unit has run for one to five days with Flushing Agent and while the unit is still warm, pull the drain plug and drain the system completely.

If possible add a small charge of new oil under pressure to flush any remaining contaminants that may be left behind.

(TD-287H REV 06/2018)

When the gear box is empty, clean the breather, sight glass, screens, and the heat exchange systems if they exist.

Change any filters and recharge the system with suitable gear lube in the appropriate ISO viscosity grade.

Hydraulic System Cleaning Procedure

Change-Out Procedure

For smaller systems, drain up to 50% of the hydraulic fluid and replace it with Flushing Agent. After two hours of operation the hydraulic fluid should be drained, the filters changed and the system charged with hydraulic oil in the appropriate ISO viscosity grade.

For larger hydraulic systems or where it is not practical to drain as much hydraulic fluid from the system, it is recommended draining off enough hydraulic fluid so that the addition of 10% to 30% of Flushing Agent can be added to the system. This mixture should then be run for a period of two to four hours to thoroughly clean all deposits and debris. Next drain the system, change the filters and refill with hydraulic oil in the appropriate ISO viscosity grade. Frequently check the filters as this is the key for collection of any discharged residue.

Note: If the hydraulic system is unusually dirty, the initial run may have to done without filters and an open line to discharge chunks of thickened hydraulic fluid, dirt and debris. Immediately follow this flush briefly for 30 minutes with a mixture of Flushing Agent and clean unused hydraulic fluid to thoroughly lean lines, valves, etc. Change the filters and recharge the system with hydraulic oil in the appropriate ISO viscosity grade.

For best results, the hydraulic system reservoir should have the following:

Venting that is kept clean.

Easy drain plugs (magnetic plugs if possible).

Baffle or a baffling system to control fluid motion. Entry and exit ports should have extended piping and bias cut close to the reservoir bottom.

Fittings, piping, exit and entry ports should be machined (no burs to control agitation).

A filtration system to help control moisture or a desiccant type filter on the breather.

Valves, gauges, pressure and operating temperature should be monitored regularly.

The use of routine oil analysis is advisable especially if operating temperatures are in excess of 150°F/65°C.

Note: The flushing cleaning and change-over procedures that are mentioned in this technical data sheet will always be superseded by specific flushing and cleaning instructions that may be listed in the manufacturer’s original equipment manual. Schaeffer Mfg. stresses the need to follow the OEM’s instructions prior to the introduction of Flushing Agent.
