M3-D Operators Manual Congratulations on your acquisition of the world renowned M3 Mixing System. You have acquired the fastest and most efficient mixing system manufactured for mixing Bentonite drilling slurry (mud). As a manufacturer of HDD support equipment, we are well aware of the extreme conditions that HDD equipment is exposed to on a daily basis.
M3-D Mixer The M3-D universal mixer is designed around the time proven M series mixers of STS. Powered by a 9 hp air-cooled diesel engine, driving a 3” centrifugal pump makes effective use of the proprietary 4 point mixing system. The M3-D can be used as a new installation or retro fitted into an existing system of tank(s).
M3-D Description, Care and Maintenance Diesel Powered Centrifugal Pump Care and maintenance of the engine and pump are covered in this manual and/or the manufacturer operator’s manuals supplied and should be read and understood. We suggest the following daily checks be carried out prior to using the system.

M3-D Description, Care and Maintenance Diesel Powered Centrifugal Pump Fig.4 CAUTION TRAPPED FLUID MAY BE PRESENT and will spill out when piping, hoses, pump or filter shear are removed. CAUTION NEVER LEAVE LIQUID IN THE PUMP CASING, PIPING, OR HOSES during freezing weather conditions, as damage will result.

M3-D Description, Care and Maintenance Diesel Powered Centrifugal Pump Grease cup instructions (Fig.5) Fill the grease cup through the grease fitting with No. 2 lithium base grease until grease escapes from the relief hole. Turn the grease cup arm counterclockwise until it is at the top of the stem; this will release the spring to apply grease to the seal.
Page 21
M3-D Description, Care and Maintenance Diesel Powered Centrifugal Pump Grease cup instructions (Fig.5a) GREASE CUP NEEDS TO BE CLEANED REGURALY The grease cup may not perform its function properly (lubricating the seal) if it is not routinely cleaned of old hard grease build-up.
M3-D Description, Care and Maintenance Filter / Shear System The filter / shear (Fig.6a) system on the M3 is an integral part of the mixing system and to operate efficiently requires daily cleaning of the stainless steel internal filter /shear. The filter / shear system is a two-piece unit (Fig.6b) consisting of an outside housing and an internal filter / shear.
Page 23
M3-D Description, Care and Maintenance Filter / Shear System continued On the left side of the unit (near the back side) is a upright “discharge manifold” (see Fig.7). The two outlets are connected to the filter shear and controlled by independent ball valves. The connections are 1 1/2” NPT thread.
M3-D Description, Care and Maintenance Venturi Mixing Tee The Venturi Mixing Tee (Fig8a.) is the very heart of this system and requires very little maintenance. However M3 unit parts may wear as a result of the application in time and require replacement. This wear will become evident, when the operator notices a reduction in the vacuum that helps pull in the dry product from the hopper.
M3-D Description, Care and Maintenance Wash Wand The M3 unit is equipped with a pressurized wash wand (Fig.9a) for clearing obstructions and accumulation in the jetting tee. It is recommended that the jetting tee be cleaned with the wash wand after the introduction of material into the hopper after each batch.
M3-D Description, Care and Maintenance Dry Hopper with Table and Hopper Valve The Dry Hopper and Table (Fig.10) are used during the initial mixing of the dry product and fluid. The hopper and table require very little daily maintenance, however care should be used that this unit does not become overloaded.
The internal tank jets are connected together in series, usually by a manifold design, (suggested by STS) were all jets receive the same amount of fluid and pressure. This manifold design is supplied with fluid from one of the outlets on the discharge manifold (Fig.11b).
Page 28
Connect the manifold to the outlet on the filter/shear of the STS Mixing Unit. Each unit is shipped with 2-4 jet nozzles that have been properly sized for the unit.
Optional Mixing Tee Shut off Valve Mixing Tee Shut off Valve Operation If the M3-D was supplied (an ordered option) with a valve on the inlet side (Fig. 15) of the mixing Tee, follow the instructions below. The unit can be used to mix polymer based drilling fluid that could (without using this valve) be over sheared.
M3-D Set-up and Installation of M3 in detail Permanent mounting of the unit The M3 unit is built on a sub frame that can be bolted down to a permanent surface like a concrete pad, pull type trailer, flat deck of a truck or inside of a truck body. Securing the unit with adequate size and grade of fasteners is the sole responsibility of the customer and not of Surface to Surface Inc.
M3-D Operating the M3 Unit Site Setup & Pre-Check SITE SETUP • CHECK for overhead hazards if unloading the unit to the ground. • UNLOAD the unit by using the sub frame lifting bale (marked) with appropriate equipment. • and position the unit on solid level surface to avoid settling or upset.
M3-D Operating the M3 Unit Starting the Engine & Pump *** The Engine Operators Manual should be consulted for a more detailed engine start up procedure for both recoil and electric start engines Starting Engine (Electric Start) • With the unit full of liquid and the pump primed, and all of the precautions taken, the engine can be started.
M3-D Operating the M3 Unit Typical Mixing Operation Mixing Operation • Operate the engine at high speed. • If not already open, open internal tank jet valve. • Open the hopper valve at the bottom of hopper where it joins the venturi mixing tee.
M3-D Operating the M3 Unit Typical Transfer/Offloading Operation Transferring Operation • On the discharge manifold of the M3 you will see a 2 outlet with a ball valve (1 1/2”NPT.) that is not being used. • A transfer hose with a minimum size of 1 1/2 in. can be attached to this outlet ball valve to carry the finished product to a holding tank or directly to the drill rig.
M3-D Operating the M3 Unit Typical Warm Weather Shutdown & Storage Daily Shut Down • Set the engine speed control lever (Fig. 13a) at the low speed position and allow the engine to run at low speed for 5 minutes.
M3-D Operating the M3 Unit Typical Cold Weather Shutdown & Storage Additional Winter and Freezing Weather Shut Down • Pump or drain remaining mixed fluid out of the tank and dispose of it according to local environmental approved practices. • Make sure the valves on the discharge manifold are open.
M3-D Operating the M3 Unit Prolonged Periods of Storage Prolonged Periods of Storage After a thorough cleaning of the internal and external components of the M3, the following steps should be applied to extend the life of your unit. • Prolonged periods of storage require extra care of the pump to protect from rusting internally. Separate the pump (as you would to replace the seal) to dry and spray with a protective oil film.
M3-D Operating the M3 Unit Optional Self-Loading Feature Self-Loading (customer to install) If the self-loading feature of The M3 is required, you will find a 1 1/2 in. NPT (suction) port located on the venturi-mixing tee below the hopper valve (Fig.14a). All units are shipped with a plug installed in the port.

M3-D Troubleshooting the M3 Unit The M3 mixing unit is of a simple design with limited moving parts or consumable pieces. The basic system works with a pump that draws fluid from a reservoir tank. The fluid then exits the pump and by building pressure, and velocity, forces the fluid through the filter / shear and into the mixing Tee.
Page 43
M3-D Troubleshooting the M3 Unit • Tank does not stir / roll the fluid inside. No fluid to the tank jets - Make sure discharge manifold valve is open. Tank jet holes plugged. - Flush fresh water through system or clean Tank jets...
