Heavy duty oilfield fluids process centrifugal pump for drilling fluid system at oilfield
Oilfield fluids 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

Oilfeild fluids process centrifugal pump definition and general information
Oilfield fluids process centrifugal pump widely used in drilling fluid solids control. 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.
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
How centrifugal pump works
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.
Centrifugal pump types in solids control
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

Application of centrifugal pump
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.
