  • (3) Sand Auger Drive Motors
  • Blender Tub Agitator Motor
  • Hydraulic Auger Positioning System Cylinder
  • 160 Gallon Hydraulic Reservoir
    • Strainers/Return Filtration
    • Sight Glass for Oil Level
    • Hydraulic Oil Cooler
  • Base System Designed for Additional Hydraulic Options


The mixing system consists of the following:

  • Suction Pump and Manifold
  • Discharge Pump and Manifold
  • Blender Tub
  • Sand Augers
  • Cross-Over Plumbing



The hydraulically driven centrifugal pump is capable of pumping base fluids in excess of 120 BPM from the supply tank to the blender tub. Mounted on the suction side of this pump, the suction manifold has twelve 4″ 206 winged input connections, with butterfly valves and (1) 8″ input connection, and includes a 10″ magnetic flow meter. A hydraulically operated valve is installed before the blender tub. Suction pump can pull from curbside or roadside.



The variety of options of discharge pumps are capable of pumping from the blender tub proppant laden slurries at rates of 125 BPM. The suction side of this pump is connected to the blender tub, while the discharge side of the pump feeds the discharge manifold. The discharge manifold has (12) 4″ 206 winged input connections with butterfly valves and an 8″ discharge connection that includes a 10″ high-signal magnetic flow meter. An 18″ removable blank is included for installing the customer supplied densitometer. Pump can discharge from curbside or roadside.



The 16 barrel capacity mix tub ensures complete and consistent blending of high density slurries. Tub is complete with the following:

  • Agitator
  • Directional Nozzles
  • Hydraulic Inlet Valve
  • 4″ Air-Actuated Bottom Drain Valve


Three standard sand augers are installed at the rear of the unit from the hopper to the blender tub, and designed to be hydraulically raised and lowered. Each auger includes hydraulic slide gates at the hopper.

  • (2) 12″ Auger at 39lb/rev (Full Flight)
  • (1) 12″ Auger at 22lb/rev (Half Flight)

  • (1) Stainless Steel Dry Add Chemical System with a 2″ auger (Standard)
