Centrifugal pump is also referred to sand pump in China. Centrifugal pump are widely used in oilfield drilling equipment and drilling mud equipment like shale shakers, desanders desilters etc.
Drilling fluid process Centrifugal pump is used to transport fluid by conversion of rotational kinetic energy to the hydraulic energy of the fluids flow. The rotational energy typically comes from an engine or electric motor. Aipu supply pumps driven by 10HP to 100HP, which are popular in drilling mud process. Pumps size are 3x2, 4x3, 5x4, 6x5, 8x6. They will perform differently under different power, voltage, or frequency.
No matter for oil and gas drilling, or Water drilling, CBM, or piling, and so on. The solids control system need pump to be power or energy supply of fluid circulation or mud recycling. From shaker compartment, we use pump to transfer drilling mud to desander or mud cleaner. From mixing tank we need mixing hopper pump to blend or compound new drilling fluid
| Model | Flow Rate | Head | Power | Speed | Efficiency |

Drilling mud solids control Centrifugal pumps used in well drilling fluids system are mechanical seal pump. Aipu produce high quality centrifugal pumps. Centrifugal pump is also called sand pump, as the dilling fluid to be processed contain large quantity drilled solid or cuttings.
Trip Pump: Trip pump will sit at trip tank to transfer mud from
trip tank into drill hole directly in special conditions. The pump
normal driven by 11 or 15kw electrical motor with a 4×3 size pump.
The mud flow 200 to 250GPM is enough.
Desander & desilter feeding pump: It is normally 8×6 size pump
driven by 55kw motor for 1000GPM mud flow for oil and gas drilling,
but 6×5 or 5×4 size pump with smaller electrical motor will be used
for smaller mud flow capacity for oil & gas drilling, coal bed
methan drilling, horizontal directional drilling or water well
drilling.
Water pump: The water pump will set on water tank with water line
supply to solids control mud tank. A diesel pump may work as
standby incase of fire.
Mixing Pump: The mixing pump normally 8×6 size driven by 55kw
electrical motor to supply mud to mixing hopper for new mud mixing
application.
Charge Pump: 1 or 2 set charge pump will sit beside mud pump for
charging application.
Oilfield Centrifugal Pump Widely Used In Drilling Fluid Solids Control.
Common centrifugal pump applications including water, sewage, petroleum and petrochemical pumping. The reverse function of the centrifugal pump is a fluid turbine converting potential energy of water pressure into mechanical rotational energy.
Centrifugal pumps are a sub-class of dynamic axisymmetric
work-absorbing turbomachinery. Centrifugal pumps are used to
transport fluids by the conversion of rotational kinetic energy to
the hydrodynamic energy of the fluid flow. The rotational energy
typically comes from an engine or electric motor. The fluid enters
the pump impeller along or near to the rotating axis and is
accelerated by the impeller, flowing radially outward into a
diffuser or volute chamber (casing), from where it exits
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
