GN Various pumps

GN Solids Control manufactures various pumps, such as centrifugal pumps, displacement positive pumps (also called screw pumps) and submersible pumps. All these pumps can be used to pump mud effectively. During the past 2015, GN Solids Control has provided many pumps to the global world. GN Solids America LLC also delivered some centrifugal pumps and screw pumps to USA clients and Canada clients.
1. GN centrifugal pumps
Centrifugal pumps are widely used when transfer mud. Many centrifugal pumps are used to pump GN hydro-cyclones which are assembled on GN mud cleaner.
GN centrifugal pumps are replacement pumps for Mission pump. As GN No.2 factory will start manufacture soon, more centrifugal pumps will be provided in the new year.

2. GN Screw Pump
GN screw pumps are mainly used to feeding decanter centrifuge or flushing cuttings dryer. Screw pump is also called positive displacement pump, which has a very good characteristic that transfer mud or slurry without mud agitating. While for the centrifugal pump, the impeller will provide a large centrifugal force to pump mud and case heavy agitating.
3. GN Submersible Pump
Submersible pump is used to pump slurry with large size solids. GN submersible pumps are mainly used to feeding HDD mud recycling system. Although they’re also used in feeding decanter centrifuge, when it meets large height difference, GN PMP pumps are usually the first choice. However, the price of submersible pump is pretty lower when comparing with GN screw pump.

Besides those above pumps, GN Solids Control also manufactures electrical control box. All GN control boxes can be used in the oil and gas area which needs to be explosion-proof. GN control box meets the Class I, Division I or Division II standard for various usages.
Now GN also manufactures VFD control panel for decanter centrifuge and cuttings dryer. All the running parameters can be adjusted easily on the control panel. When using GN VFD control box, a air compressor need to be equipped in order to provide high pressure air into the control box: one is to cool down the inside temperature, the other is for anti explosion.

GN Pumps in Solids Control area

GN Solids Control is a Chinese leading manufacturer providing various pumps including shear pump, centrifugal pumps, submersible pump or displacement pumps. All of these pumps are equipped on GN mud recycling systems with different working functions.
1. GN Shear Pump
Shear pump is especially designed for mixing bentonite and polymer to former the active drilling fluid. In order to decrease the mixing time, more and more oil and gas companies are paying great attention to the mixing process. As we all know, the drilling fluids need to be strictly and carefully mixed and sheared in order to have an effective drilling fluids property.
By using GN shear pump, the bentonite and polyer can be dispersed thoroughly in the water. It can help to increase the hydration degree largely. GN shear pump also helps to reduce the use of water by over 15% and reduce the usage of more than 30% bentonite. On the other side, GN shear pump dilutes the high molecular weight polymer largely. GN shear pump provides highly efficient shearing drilling fluids pretty fast.

2. GN Centrifugal Pump
Centrifugal pump is mainly used to provide drilling fluids and transfer drilling fluids to different equipments as trip pumps. GN centrifugal pumps are can be used to replace Mission Pumps.
GN centrifugal pump is using mechanical seal which is made of tungsten carbide. All the bearings are using world famous bearings. GN centrifugal pumps can also be used for feeding desander, desilter or some other equipments.

3. GN Submersible Pump
GN submersible pump is used to pump the drilling fluid with large density in a deep tank. The pump is made of wear proof alloy for long time usage.
GN Solids Control also has positive displacement pumps also called screw pumps are also very popular in transfer drilling fluids without agitating or shearing. Welcome to connect with GN Solids America LLC if you need more info.
