Matex fluid injector for Environmentally Safe Oil
Matex fluid injector

The Matex Fluid Injector is AIR operated and TIME activated. It is completely self-contained and easy to install. The Matex Fluid Injector can inject a wide range of different products. Such as Tri-Lube, RDO-302 ES, Hole Control, Vibra-Stop, Liquid polymers, Foam etc. If injecting foam, use a Matex soluble lubricant to avoid rust that could result from the foam.

The pump is designed to deliver a measured amount of product each injection to ensure a proper mixture. The pump has been designed with only one moving part to ensure low maintenance.

The timer assembly is available in a range of different voltages. It’s designed to measure the exact amount of injection needed to deliver the amount of product desired. The timer has a setting dial on the face of the timer. This is for the ease of increasing or decreasing the amount of product needed. The timer can be pre-set for lubricating at a set rate.

All parts are warrantied of manufacturers defects for a period of one year of normal operation using only Matex products. For warranty and return policy information please contact

Pump is not warrantied if dirt and debris is found in the check valves or pump.

Note: The air mixing motor must be oiled with two drops of an air oil daily. This air oil can be sourced from any local supplier of hand held air tools worldwide

Matex Environmentally Safe Oil Torqueless Bucket

• RDO 302 ES is a unique product developed for all types of drilling where rock drill oils are used. Such as D.T.H., air tracks percussive drills, casing drivers and top hammers. This prevents wear and improves performance.
• RDO 302 ES reduces the potential of surface or groundwater damage during mining production, mineral exploration, construction of roads and pipelines, quarrying, water well drilling, and oil and gas exploration.
• RDO 302 ES has lubricating compounds that are not washed off by moisture, thus offering protection when drilling with water. Rust does not develop on internal parts when the hammer is not used. Lubrication is better controlled and consumption reduced by using RDO 302 ES.
• RDO 302 ES has a special filming additive that prevents piston scuffing and heat buildup. Reducing purchases of internal hammer parts dramatically.
• RDO 302 ES has a viscosity that allows the lubricant to flow freely to areas requiring lubrication. Use in all in-line lubricators or as a batch lubricant poured down the drill pipe.
• RDO 302 ES provides an environmentally safe product that lubricates more effectively than conventional Rock Drill Oils while reducing contamination of surface and groundwater. Particularly suited for drilling in sensitive areas such as adjacent to streams and lakes, or where groundwater protection is important.
• RDO 302 ES is particularly suitable for drilling uncontaminated WATER WELLS AND MONITOR WELLS. Also available as a soluble lubricant.

RDO 302 ES MW is specifically for monitor well use. Environmental data available upon request. Chemical parameters available upon request.

Hole Control
