Features and Benefits
The MAC Junior 1200E was designed to mix drilling fluid, clean and recycle used drill fluid, and maintain proper drilling fluid in an active tank for the drilling rig. The MAC Junior 1200 is built as one unit that includes 3 tanks, a manifold assembly of hydro-cyclones, a STS M2 mixer and all the valves and piping to needed to create a smooth and effortless system needed to satisfy the customer’s needs.
The unit is designed to be operated on ground level with a tank height of 50 inches, so the operator can over-see the process, and visually inspect inside of the tanks without ever having to climb up or down causing a safety issue. When the unit is to be transported from location to location, the unit is jacked up with the 3 onboard jacks letting the wheels rotate down and into position, were they are secured and locked in place. This creates 12” of ground clearance for transporting over uneven terrain. Once on location, lower jacks and take the weight off of the wheels, release the locks and lower to ground level.
The mixer located at the rear of the unit is designed around the time proven M series mixers of STS. The MAC Junior 1200E is powered by a 10HP Teco/Westinghouse electric motor, driving a 2” centrifugal pump, making effective use of the 4 point proprietary mixing system. With the proper valve selection, this one motor and pump will do all of the functions required to operate the unit effectively and efficiently, thus reducing mechanical and maintenance issues.
With a hopper height of only 36” from the ground, operator fatigue from loading bags into the hopper is reduced. The mixer blends and shears the new drilling fluid in the rear 300 us. gallon tank. A set of 5-1 injector nozzles in combination with a rolled bottom tank design keeps the fluid agitated and consistent. When the operator has the proper drill fluid made, simply rotate a valve on the mixing unit and route the fluid to the front active tank. The active tank will hold 600 us. gallons of drilling fluid for the drilling rig to draw from. This tank is also designed with a rolled bottom and a set of 5-1 injector nozzles to keep the fluid agitated and consistent.
The tank in the center of the unit has a capacity of 300us. gallons for storing “dirty, spent” drill fluid from the drill hole. This tank is filled by a customer supplied pit pump usually of the 2” size. When the “dirty” tank is full, the pump on the mixer is used to draw “dirty” fluid from the center tank and route it to the front mounted hydro-cyclones. While routing fluid to the hydro-cyclones the pump also uses the “dirty” tank’s rolled bottom and set of 5-1 injector nozzles to keep the dirty fluid agitated and consistent. The hydro-cyclones are 2 1/2” with a capacity of 16 us.gpm each and a D-cut of 5 micron. As the fluid is processed with the hydro-cyclones, the over-flow (clean) fluid is routed into the active tank for reuse. The underflow (solids) are routed out and away for customer disposal or optional secondary treatment. Each tank is open top and has side clean out access. The tanks are equipped with the required inlet-outlet connections on both sides of the tank to allow for better external hose routing and to eliminate hoses over the top and tied. The frame has many securing and tie-down points located in key spots.
