Surface to Surface Inc. M2 Series (Hose Hook-ups) FLUID OUTLETS [to Drill Rig & Tank Guns] ** 1 1/2" NPT ** PUMP INTAKE [in from Tank] ** 2" NPT ** This line should have a valve installed at the tank to facilitate shut down or reapirs.
Surface To Surface Inc. 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 M2 series mixer. Thank you, for choosing the M2 series mixer.
M2-E Mixer Electric The M2-E universal mixer is designed around the time proven M series mixers of STS. Powered by a 10HP Teco/Westinghouse electric motor, driving a 2” centrifugal pump, making effective use of the proprietary 4 point mixing system. The M2-E may be used as a new installation or retrofitted into an existing system of tank(s). Since the unit is connected by hoses and not hard pipe, the placement of the mixer verses the tank(s) is less restricted and a configuration to suit the needs of the contractor is easier to achieve.
M2-E Description, Care and Maintenance Electric Powered Centrifugal Pump Care and maintenance of the motor 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.

CAUTION NEVER LEAVE LIQUID IN THE PUMP CASING, PIPING, OR HOSES during freezing weather conditions, as damage will result.

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.

If the grease cup is always “topped up”...
M2-E922 Description, Care and Maintenance Filter / Shear System The filter / shear (Fig.6a) system on the M2 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 26
M2-E922 Description, Care and Maintenance Filter / Shear System continued On the bottom of the filter / shear housing (Fig.7) are two outlets that have 1 1/2” NPT ball valves connected to them. One of the outlets is to be connected to the internal tank jets inside of the reservoir tank (explained further on in this manual) and the other outlet is to be used as a discharge for the fluid after it is mixed.
M2-E Description, Care and Maintenance Venturi Mixing Tee The Venturi Mixing Tee (Fig. 8a.) is the very heart of this system and requires very little maintenance. However M2 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.
M2-E Description, Care and Maintenance Wash Wand The M2 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.
M2-E Description, Care and Maintenance Dry Hopper with Table and Hopper Valve The Dry Hopper (Fig.10) is used during the initial mixing of the dry product and fluid. The hopper requires very little daily maintenance. Keeping the inside surface of the hopper clean will help the dry product flow smoothly into the hopper valve and into the mixing tee.
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 31
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.
M2-E Set-up and Installation of M2 in detail Permanent mounting of the unit The M2 is built on a sub frame with isolators (pucks) attached to the bottom. The unit can be fastened down to a permanent surface like a concrete pad, pull type trailer, flat deck of a truck or inside of a truck body.
M2-E Operating the M2 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. •...

M2-E Operating the M2 Unit Prolonged Periods of Storage Prolonged Periods of Storage After a thorough cleaning of the internal and external components of the M2, 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.
M2-E Troubleshooting the M2 Unit The M2 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 45
M2-E Troubleshooting the M2 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 Hose is disconnected from tank jets - Reconnect hose No fluid flow/ low fluid flow - See above solutions •...
