Operators Manual
Congratulations on your acquisition of the patented (U.S. 5,779,355) M3-G 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. Surface To Surface strives to overcome these
conditions, with better design and manufacturing practices. Please feel free to call our toll free number
(1-800-567-0978) if you have any questions or concerns about your M3-G.
Thank you, for choosing the M3-G
The M3-G mixing unit was designed to mix dry or liquid drilling products with clean water, into a slurry.
The slurry is continually circulated through the mixing cycle until it reaches the desired consistency. The
operator can then transfer the final product to a holding reservoir or directly to the drilling equipment.
WHEN transferring, the flow to the drill rig may reach up to 35 p.s.i. Check the drill rig
manufacturers specifications regarding maximum inlet pressures allowed for their pump.
The M3-G mixing unit consists of a gasoline powered centrifugal pump, filter/shear unit, venturi mixing tee
assembly, dry hopper and table, pressure wash wand and a set of tank internal jet guns. These components
are all mounted on a frame type skid, built for lifting or solid mounting. For ease of interpretation, looking at
the mixing unit hopper straight on will be considered looking at the front of the unit. Hence the other side,
will be the rear and the ends will be right or left end.
LIFTING lugs or the lift points identified in the skid structure must be used in order to safely lift the
unit.
Care and Maintenance
Gasoline Powered Centrifugal Pump
Care and maintenance of the engine and pump are covered in the manufacturer operators manuals supplied.
However, we suggest the following daily checks be carried out prior to using the system. Check the gasoline
fuel tank is full. Check oil level by removing the oil plug / dip stick, and viewing the level. Check the engine
air filter (due to environmental conditions). Check that the water suction tee valve is open and the reservoir
tank has sufficient liquid to supply the centrifugal pump.
B BEFORE starting or restarting the engine and centrifugal pump, make sure any valves installed on
the pump intake line are open.
BEFORE STARTING OR RUNNING THE ENGINE BE SURE THE PUMP IS PRIMED! This is
checked by slowly unscrewing the plug on the top of the centrifugal pump. Water will leak out as the
plug is loosened or a visual inspection can be made if the plug is removed. The centrifugal pump
WILL be damaged if allowed to cavitate or run dry.
IMPROPER installation of the mechanical seal will result in leakage and possible damage to the seal.
All maintenance, operating and repair of this unit, must be done per the instructions in the operators
manual for safety and reliability.
NEVER leave liquid in the pump casing in freezing weather conditions, damage will result.
