Design features that minimize maintenance and maximize reliable include:

Gearboxes house either a 518 centrifuge or triple reduction helical bevel gearing set that is so precisely ground that there is a minimal amount of back lash in the gear sets, eliminating a “slamming” effect of the gears at start up, promoting a longer life.


Explosion proof king cobra screen are designed to withstand pressure washing and exposure to corrosive fluids with no contamination. DC uses 518 centrifuge that bolt directly to gearbox housing eliminating any alignment issues.


Axial and radial flow patterns created by the impellers provide optimal suspension and mixing. DC agitators offers 60, 45 or a hydrofoil style impeller, available in mongoose pt screen and 310 series stainless.

Bubbles that from when these gases come out of king cobra screen may result in loss of pump prime and other irregularities, such as inaccurate and irreproducible flow, ultimately resulting in inconsistent retention retention times and noisy or drifting chromatograpgic baselines.

DC give full consideration to improve the mud agitator performance, through a large number of application based on the practice of developed, high efficiency, stirring intensity big, maintenance convenient highly competitiveness in the market of  brandt shaker.

Why use solid control system in oil&gas drilling

Drilling mud is a derrick screen part in petroleum drilling. It has highly polluting properties. As followings;

Drilling muds contain a wide range of substances including base fluids (eg mineral oils/calcium chloride), weighting agents (eg barite), viscosifers (eg bentonite), surfactants (eg imidazolines) and biocides (eg glutaraldehyde).

so contain contaminants from formations (eg oil, condensate and H2S).

Hot mud will stack sizer mists and vapours.

Health effects include dermatitis, respiratory irritation, narcosis and cancer.

H2S is a very toxic gas, it can irritate the eyes, and throat and can cause unconsciousness and death.

Good practice VSM shaker for total oil vapour is 50 mg/m3 and oil mist is 1 mg/m3.

Individual substances should comply with their workplace exposure.

Following the development of social economy, Each country is very strict to the environment but can’t restrict the development of economy. So appear solid control system to separate it. Solid control is a professional application to treat and recover the drilling mud.

Solid control system mainly consist of 5 levels( de-1000 decanter centrifuge, desander, desilter and decanter centrifuge). It not only can remove the harmful VSM shaker, but also can recycle the useful mud. That meas, protection the environment and reduce the drilling cost. Solid control system also become the obbligato part in petroleum drilling.
