M-750D Operators Manual Congratulations on your acquisition of the world renowned M-750 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.
Powered by a 21.9 water cooled electric start diesel engine, driving a 4 inch centrifugal pump making effective use of the proprietary StS mixing system, this Bentonite Mud Mixer is capable of providing 750 gallons of full yield mud to your drill rig in less than eight (8) minutes. Added benefits to this unit include the ability to draw water from a second tank and send mud to your drilling rig or storage tank without the use of a second pump.
M-750D Description, Care and Maintenance Polyethylene Plastic Reservoir Tank (750 us. gal) Maintenance of this tank is required, but is simple. The tank should be cleaned on a regular basis by opening the drain cap on the tank tee, located at the bottom right end of the tank (see Fig.1) and or open the customer installed bottom tank drain (see Fig.2) and rinse the tank with clear water.
M-750D Description, Care and Maintenance Polyethylene Plastic Reservoir Tank (750 us. gal) INSTALLATION OF TANK DRAIN (CUSTOMER INSTALLED) • Find a suitable location on the tank floor for the drain to be installed, taking into consideration the placement of the unit on a trailer. LOOK under the deck for obstructions (cross-members, wiring, and axles, ect.) Allow room for a shut off valve.
M-750D Description, Care and Maintenance Diesel Powered Centrifugal Pump Care and maintenance of the engine and pump is 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.

M-750D 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.

M-750D 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 22
M-750D 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.
M-750D Description, Care and Maintenance Filter / Shear System The filter / shear (Fig.6a) system on the M-750 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 24
M-750D Description, Care and Maintenance Filter / Shear System continued On top of the filter / shear housing (Fig.7) are two outlets that have 2” NPT ball valves connected to them. One of the outlets (labeled) is connected to the internal jet gun inside of the reservoir tank (explained further on in this manual) and the other outlet (labeled) is to be used as a discharge for the fluid after it is mixed.
M-750D 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 M-750 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.
M-750D Description, Care and Maintenance Wash Wand The M-750 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.
M-750D 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.
M-750D Description, Care and Maintenance Internal Tank Jet Gun The Internal Jet Gun (Fig.11a) is located inside the polyethylene plastic reservoir tank, and its function is to keep the slurry product in the tank moving. This function assures the elimination of dead spots in the tank and a consistent mixture of fluid.
M-750D Set-up and Installation of M-750 in detail Permanent mounting of the unit The M-750 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.
M-750D Operating the M-750 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 fork tubes (marked) with appropriate equipment. • and position the unit on solid level surface to avoid settling or upset.
M-750D Operating the M-750 Unit Starting the Engine & Pump *** The Engine Operators Manual should be consulted for a more detailed engine start up and shut down procedures. Starting the Diesel Engine • Make sure the fuel shut off valve located under the fuel tank or on water separator is open.
M-750D Operating the M-750 Unit Typical Mixing Operation Mixing Operation • Operate the engine at high speed. • Open the hopper valve at the bottom of hopper where it joins the venturi mixing tee. • Introduce the dry or liquid raw material into the hopper.
M-750D Operating the M-750 Unit Typical Transfer/Offloading Operation Transferring Operation • On the top of the filter / shear housing of the M-750 you will see a 2 in. ball valve (2”NPT.) marked “Drill Fluid”. • A transfer hose with a minimum size of 2 in. can be attached to the ball valve to carry the finished product to a holding tank or directly to the drill rig.
M-750D Operating the M-750 Unit Typical Warm Weather Shutdown & Storage Daily Shut Down • Push in the engine speed control tee handle (Fig. 13a) to the low speed position and allow the engine to run at low speed for 5 minutes.
M-750D Operating the M-750 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 “Tank Gun” and “Drill Fluid” valves are open.
M-750D Operating the M-750 Unit Prolonged Periods of Storage Prolonged Periods of Storage After a thorough cleaning of the internal and external components of the M-750, 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.
M-750D Operating the M-750 Unit Optional Self-Loading Feature Self-Loading (customer to install) If the self-loading feature of The M-750 is required, you will find a 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.

M-750D Troubleshooting the M-750 Unit The M-750 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 42
M-750D Troubleshooting the M-750 Unit • Tank does not stir / roll the fluid inside. No fluid to the tank jet gun - Make sure “Tank Gun” valve is open. Tank jet gun holes plugged. - Flush fresh water through system or clean Tank jet gun...

Grease Seal Installation Instructions Centrifugal Pump Application When replacing the sea, never mix old and new parts. Wear patterns on the old seal faces cannot be realigned during reassembly, and use of old parts can result in premature failure of the new seal. Before installing the seal, inspect the bore of the seal liner for excessive wear or grooves that might cause leakage or damage to the seal packing rings.
