NONO pump is an important feeding pump for drilling fluid decanter centrifuge and widely used in Russian Market. At the end of March, DC Delivery 16 sets MEMO MONO pump for Russian clients who is the second time to purchase the pump from our factory.

Mono Pump

NETZSCH Progressing Cavity Pumps operate at a constant torque requirement for a specific operating pressure. The speed of the pump does NOT affect the torquerequirement. For example: a pump running at 60psi output pressure at a speed of 200 revolutions per minute requires the same toque input as if it were running at 60psi output pressure at a speed of 600 revolutions per minute. The only exception to this rule is during pump startup; at the moment the pump starts the motor must provide more torque than the pump requires when it is running. This is due to the force of static friction that the motor must overcome in order to begin rotation. Although this is only amomentary force, enough torque has to be available to break the static load.

Additional features
∙High suction capacity – up to 9 mH2O
∙Direction of rotation and flow can be reversed
∙Can be installed in any position
∙Quiet, smooth running
∙Temperatures from – 20 °C to + 200 °C

Centrifugal pump/feeding Pump China factory

Usually, oilfield centrifugal pump is a machine which converts mechanical energy into the kinetic energy of oilfield centrifugal pumped fluid for the purpose of transporting that fluid from one point to another.

But in order to be classified as a centrifugal pump, oilfield centrifugal pump needs to have two unique components: the first is a rotating disc with curved blade like vanes on it called an impeller, and the second is a specially shaped pipe called a volute casing which contains the impeller and the pumped fluid.

Screw pump to be as the feeding pump for centrifuge delivery

DC screw pump can be working for feeding decanter centrifuge. And can also feeding clean water for flushing use. DC is a hydraulic screw pump manufacturer and can supply screw pump according by customs’ requirement.

screw pump

The screw pump is an ideal mud pump to feed drilling fluids for decanter centrifuge since the fluids may flow along with the shaft with a very slow inner flow speed, which will not change the pump’s capacity, but will keep the pressure steady so that no vertex or agitation will be produced. Besides, the screw pump can also be used in the drilling waste management for wet mud and cutting transportation.

The screw pump is of compact structure, small volume, easy maintenance. Rotor and stator are wear parts of this pump, which are convenient to replace.

Horizontal sand pump using effect

Horizontal sand pump is an important equipment in oil rig mud cycling system.  Sand pump is a kind of centrifugal pump .DC produce the pump with reliability 、 heat-resistant 、large flow 、long life 、low- energy consumption 、easy maintenance and other advantages.

Structure of horizontal sand pump

The horizontal sand pump adopts the axial suction structure, horizontal or vertical structure, composed of a motor, a pump seat, a pump shell, an impeller etc., using shear coupling (horizontal pump) or plum coupling (vertical) connection, mechanical or combined sealing structure, the main vice impeller combination.


Working principle of sand pump

After the centrifugal pump started, the pump shaft drive impeller together to do high speed rotation, forced beforehand filling between the blades liquid rotation, under the function of inertia centrifugal, liquid does a radial motion from the impeller center to peripheral. Liquid won energy in the process of flow to impeller movement, static pressure energy increases, velocity increased. After liquid depart from impeller to enter into pump casing.

Centrifugal pump for drilling fluids solids control

An oilfield solids control system needs many centrifugal pumps to sit on mud tanks. The pumps are generally used to transfer drilling mud to make it circulate through tank system. According to mud feeding and drilling flow locations we name the centrifugal pump as feeding pump for desander / desilter or mud cleaner, mixing pump for jet mud mixer, trip pump for trip tank and supercharging pump for rig mud pump.

Submersible slurry pump seller

A submersible slurry pump is a device which has a hermetically sealed motor closely coupled to the pump body. The whole assembly is submerged in the fluid to be pumped.

Slurry Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi- shrouded with the agitating vane on the vane extended.

submersible pump

The submersible pumps operates in a vertical position. Although their constructional and operational features underwent a continuous evolution over the years, their basic operational principle remained the same. Produced liquids, after being subjected to great centrifugal forces caused by the high rotational speed of the impeller, lose their kinetic energy in the diffuser where a conversion of kinetic to pressure energy takes place. This is the main operational mechanism of radial and mixed flow pumps.

The pump shaft is connected to the liquid/gas separator or the protector by a mechanical coupling at the bottom of the pump. Well fluids enters the pump through an intake screen and is lifted by the pumps. Other parts include the radial bearings ( bushings ) distributed along the length of the shaft providing radial support to the pump shaft turning at a high rotational speed.
