Centrifugal pump is widely used in solids control system of oil and gas drilling. Centrifugal pump is worked as the feeding pump to drilling mud cleaner, drilling mud desander, drilling mud desilter, as well as an important part of jet mud mixer. No matter for oil and gas drilling, or water drilling, CBM, or piling. The solids control system needs the centrifugal pump to be power or energy supply of fluid circulation
Centrifugal pump is made of the pump head, explosion-proof motor, and base. Pump head there are 8x6, 6x5, and 3x2 for option. Motor including explosion-proof and non-explosion-proof. And the electrical parts can be ATEX certified against customers' requirements.

Applying classical mechanics theory, assuming viscosity of the
liquid equal 0 and no energy loss for the work of energy
transferring from impeller to the streamlines which means that, all
separate flow will be uniforms (this approximations of physical
reality to get the simpler as solid state mechanism than hydraulic
mechanism
General explanation: Like most pumps, a centrifugal pumps convert
rotational energy, often from a motor, to energy in a moving fluid.
A portion of the energy goes into kinetic energy of the fluid.
Fluid enters axially through eye of the casing, is caught up in the
impeller blades, and is whirled tangentially and radially outward
until it leaves through all circumferential parts of the impeller
into the diffuser part of the casing. The fluid gains both velocity
and pressure while passing through the impeller. The
doughnut-shaped diffuser, or scroll, section of the casing
decelerates the flow and further increases the pressure
In the drilling fluid solids control system centrifugal pumps are
used as transfer pump. Mainly pump drilling fluid to desander
hydrocyclone, desilter hydrocyclone. They also are combined
together with mud hopper to be jet mud mixer or mud mixing pump.
Pumps work as power transition tool.
Drilling fluid solids control requests many centrifugal pumps to be
fit on mud tanks. According to function, we call centrifugal pumps
as sand pumps, submersible slurry pumps, shear pumps, charging
pumps, etc. They are defined for their different functions, but
their working principle is the same
Usually in drilling fluid solids control there are horizontal
centrifugal pump and vertical centrifugal pump. The difference is
motor installation direction and pump feed inlet position.
To select either of installation way we need to consider the actual
operation condition and general space. Presently, except
installation way, there are different types pump on the seal.
Mechanical sealed pump are more popular since the stable
performance and reliable quality
