Centrifugal pump principle

Centrifugal pump is combined with impeller and casing. Drilling fluid will be sucted from impeller side, when impeller rotates at high speed there will be centrifugal force and gain power or pressure. Then fluid flow through impeller path will produce pressure out. The drilling mud will come out under certain pressure.

Advantages of centrifugal pump 

The bearing pedestal, axles and other components of all models centrifugal pump are universal,
The main components are all wear resistant ductile iron and resin sand to manufacture, the using life is long and nice exterior.
The surface of centrifugal pump all use sand blasting treatment, the paint uses the anticorrosive epoxy zinc rich paint and high pressure airless process construction.
All bolts, nuts, flat gaskets and split cotter pin must be galvanized but don’t have chromeplate and nickel plating.

Centrifugal pumps that are driven by electric motors are responsible for moving the drilling fluids to various areas of the system within the cleaning process. Pumps and motors should both be sized correctly to adequately handle the systems volume needs.

The centrifugal pumps may feature either mechanical seals or rope packing, depending upon the pump type. Mechanical seals are relatively maintenance free, but rope packing requires proper attention. Rope style packing allows some fluid “leakage” from the packing area. Do not tighten the packing housing down to stop the leaking completely, or seal and shaft damage will occur. You should always maintain a slow drip when using rope type packing.


Maintaining the Life of an HDD Mud Pump Whether your mud system features an on-board triplex mud pump, or you are using a stand- alone mud pump, care should be taken to ensure your systems charge pump adequately feeds the pressure pump, or cavitation will occur within the triplex causing costly damage. One final thought: Beware of unnecessary gimmicks that could cause costly downtime in the field. In regards to this type of equipment, simple, easy-to-operate and easy-to-field service systems are your best bet.

Single screw pump has been widely used by developed countries, it is also called MONOPUMPS. Because of its good performance, it has been applied more and more widely in Domestic and abroad recently.

Single screw pump is an ideal equipment used for feeding slurry for decanter centrifuge in solids control system. The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of the special geometry shape of the two parts, they form pressurize capacity separately.


DCG series Single screw pump is a kind of rotor type displacement pump,the main parts be include of stator and rotor. Rotor is drived universal coupling to rotation to form a confined space in the pump. The liquids is sucking up & pumping in the pump continuously & constantly. Due to the liquid be through the confined space, so this kind of pump could pumping liquid with high viscosity & mixed solid. It is widely used for feeding the drilling fluids decanter centrifuge.

General speaking, Single screw pump can be act as a Universal pump. The rotating speed is adjustable, the rated pressure of pump outlet is increasing with the class of the motor, the pressure will increase 0.6Mpa when the motor increase one class, so it is widely used in many industries.

Working principle of sand pumps 

The sand pump is the most used pump type in the word. The principle is simple, well-decribled and throughly tested, and the pump is robust, effective and relatively inexpensive to produce. The sand pumps creates an increase in pressure by transferring mechanical energy from the motor to the fluid through the rotating impeller. The fluid flows from the inlet to the impeller centre and out along its blades. The centrifugal force hereby increase the fluid velocity and consequently aslo the kinetic energy is transformed to pressure.

Features of sand pumps

1.Semi open impeller design
2.SKFor FAG premium bearings
3.Cemented carbide mechanical seal
4.Wide range application

DC produce the sand pump with reliability 、 heat-resistant 、large flow 、long life 、low- energy consumption 、easy maintenance and other advantages. Any questions please contact us.

Drilling fluid pump is one special pump in centrifugal pump. We also call it as sand pump which is an important unit in the whole solid control system. It is mainly used to transfer drilling fluid for desander, desilter, and provide sufficient power for mixing drilling fluid.

SB Series centrifugal pumps are distinguished by high efficiency, low energy consumption, several options, and a wide range of flow rates and pressures.


High efficiency
A precision-engineered pump and motor provide high efficiency and gentle product treatment. The robust design and tight tolerances together with the advanced impeller design minimize recirculation and ensure the efficient transfer of energy.

Optimal pump design
The impeller design ensures efficient and gentle handling of the product as it moves through the pump. This ensures product integrity and minimizes NPSHr ( Net Positive Suction Head required).

Low energy consumption
Making pump energy use more efficient presents huge potential for energy savings. The optimized pump design and premium motor of our centrifugal pumps often deliver greater energy efficiency than similar premium pumps and up to 50% compared to similar mid-range pumps.

Centrifugal sand pump is a transporting part of solids control circulating system of oilfield drill rig, and be used to offer drilling fluid with certain volume and pressure to desander,desilter or mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head.

DC Solid control newly designed according to features of petroleum and natural gas drilling equipment.It adopted the axial suction structure. The Flow components is wear-resistant cast iron, so it is applicable to transport corrosive drilling fluid with suspended particulates or other liquid media under similar work condition.

centrifugal pumps


1.Strong universality and interchangeability of the components.
2.The less leakage of the shaft sealing.
3.Reliable operation, long service life and convenient maintenance.

Centrifugal sand pumps are generally placed in fluid or oil tanks that have sunken or become filled with sand, and then move sand through a series of pipes and junctions. They may possibly even move sand through other pumps that may be incorporated to maintain the material pressure through the entirety of the system.
