The drilling mud could be seen as the blood
of the drilling process, the solids
control equipment is used to remove the cuttings to purify the blood. While
where is the power of the blood circulation coming from? It is the pump unit
that transfers the drilling mud in solids control system from one equipment to
another, make the continuously recycling of mud available.
As a leading China based solids control
equipment manufacturer, GN solids control could provide the full line of
equipment used for drilling mud cleaning. Besides the primary solids control
equipment like shale shaker, mud cleaner and centrifuge
unit, GN also provides several types of pump for different application in mud
recycling system.
Centrifugal pump is the most widely used
mud transferring equipment. This type pump uses tungsten carbide mechanical
seal, with open design of impeller that lowers the axial thrust load. Centrifugal
pump could be used as feeding pump for de-sander and de-silter cyclone unit.
For some deep drilling project, the mud system need a trip tank, this type pump
can also be used as trip pump. The jet mud mixer unit always equipped with
centrifugal pump as mud mixing pump to transfer chemicals into the drilling
mud.
Shearing pump is also always equipped with
mud hopper. With the impeller material of high wear resistant cast iron, the
shearing pump is used to shear the polymers that used in the drilling mud to
keep proper mud specific gravity. GN’s shearing pump is available as a
belt-driven or diesel-driven package including hopper, mud gun and transfer
line orifice plate.
GN’s PD pump is a single screw pump. This
pump is an ideal chosen for feeding to decanter centrifuge unit as it transfer
the drilling mud without shearing and agitating. This pump, with stator
material of elastomeric material, has particular advantages to transfer fluids
of high viscosity and hard suspended particles included.
Vertical submersible slurry pump is another
choice as feeding pump to centrifuge. This pump is always installed vertically
to transfer medium with high concentration particles. Submersible pump is also
widely used to transfer the mud from mud pit to the shale shaker in the HDD mud
recycling system.
