SUCTION PUMP AND MANIFOLD:

The hydraulically driven centrifugal pump is capable of pumping base fluids in excess of 130 BPM from the supply tank to the blender tub. Mounted on the suction   side of this pump, is a manifold that has connections that are set up to customer preference, and includes a 10” magnetic flow meter. A hydraulically operated valve is installed before the blender tub. A hydraulically operated valve is installed before the blender tub.

DISCHARGE PUMP AND MANIFOLD:

The variety of options of discharge pumps are capable of pumping from the blender tub proppant laden slurries at rates of 130 BPM. The suction side of this pump is connected to the blender tub, while the discharge side of the pump feeds the discharge manifold that has

connections that are set up to cusotmer preference that includes a 10” high-signal magnetic flow meter. An 18” removable blank is included for installing the customer supplied densitometer.

BLENDER TUB:

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