GN solid vacuum pump

GN Sludge vacuum pump

GN solid vacuum pump is called sludge vacuum pump, It’s a 100% pneumatic driving pump, which can do transfer work for solid and sludge, it will be connect with air compressor.

It’s a vacuum loading solids transfer pump, GN vacuum pump have 3 different model, GNSP-40, GNSP-20 and GNSP10, The maximum transport capacity of the three models for clean water is 10 cubic meters, 20 cubic meters and 40 cubic meters respectively. According to different material conditions, suction and discharge height and distance, the conveying capacity will be different. The max solid content is 80%, and the max particle size is 75mm for GNSP-40B.

GN solid vacuum pump is often used to transport oily sludge to the treatment system.

GN solid vacuum pump has obtained European CE certification and ATEX explosion-proof certification.

For more information pls feel free t contact GN, suitable proposal will be sent you accordingly.

GN disc stack separator

GN disc stack separator 

Recently, GN has competed the manufacturing of two units 3-Phase disc stack separator, and will be arrange to send to the overseas clients as soon as possible.

Due to its high running speed and centrifugal separation factor, as usual, disc separator is used to separate two miscible liquid phase with small density contrast or as a clarification equipment to remove the fine solid particles from the liquid.

In this order, the model of the disc stack separator selected by the clients is GNSD225, with a piston diameter of 730mm, The slag discharge action of the sliding piston is automatically controlled by a PLC fully automatic control cabinet specially designed with safety protection devices.the rotation speed of 4500RPM, We make of duplex stainless steel 2507, which is the higher quality, the control cabinet with touch screen and PLC, operators can monitor and operate the equipment. We also equipment with a series of sensors that can detect the speed, vibration and temperature of key components of the device.

In addition to 3-phase disc stack separator, GN Separation can also provide two-phase decanter centrifuges and three-phase decanter centrifuges. For more information on centrifugal separators, please feel free to contact GN Separation at any tim

GN sludge vacuum pump

A couple day agon, GN Separation produced and shipped a batch of decanter centrifuges and inclined plate clarifier for mud dewatering projects.

When you need separate solid /liquid mixtures with high solids content, you can choose a decanter centrifuge.Decanter centrifuges can be optimally adjusted for specific applications. Applications range from sludge dewatering to classification or wet classification to solid classification.

Three phase decanter centrifuge is widely used in dewatering project. We have different model due to the handling capacity, the smallest model is GNLW-224FT, and the bigget model is GNLW-764FT.


Decanter Centrifuge Function

1)Dewatering sludge / mud and suspensions

2)Thickening sludge or mud

3)Clarifying different type liquids

4)Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase

5) Classifying solids in a wet suspension by grain size

6) Separation of solids according to various densities


GN can not only provide users with Dewatering Decanter Centrifuges, rely on GN rich production line of separation and conveying equipment.

For more information on GN three-phase decanter centrifuge, no hesitate to contact GN Separation.

Decanter centrifuge

GN has designed, developed and produced different kinds of centrifuges for  solid/liquid and liquid/liquid separation.

GN clarifying decanter centrifuge is C series decanter centrifuge with beach angle of 20 degree. It suits for material of small particle size, low density difference between solids and liquid, moderate viscosity, moderate concentration.

The smallest model is 224FT which is come with 220MM Bowl Diameter and the max G force is 3200G, The beach angle of the C series clarifying decanter centrifuge is 20 degree, so the bowl cone section is short, and the straight section of the bowl is longer, it will give the bowl to have a longer clarifying section.

GN can not only provide users with high-tech Clarifying Decanter Centrifuge, but also provide users with Clarifying Disc Separator with high rotating speed and G force is up to 12000 G, which can carry out multi-step clarification treatment for users’ materials, so as to achieve the most desired effect for customers.

8 Sets Inclined Plate Clarifier and 6 Sets Decanter Centrifuge for mud treatment6 Sets Decanter Centrifuge for mud treatment

Recently GN separation completed 8 sets inclined plate clarifier and 6 sets decanter centrifuge, 8 sets inclined plate clarifier will be sent to overseas customers for industrical sludge treatment, 6 sets decanter centrifuge will be sent to the domestic major drilling company for driiling mud treatment.

In this order, the overseas customer choose the model of GNIPC-25A for inclined plate clarifier, GN IPC design incorporates inclined plate settling surfaces pitched at a 55° angle from the horizontal with uniform plate spacing. Due to plate angle the solids slide down the plates into the sludge hopper below the plate pack. Herewith pls find the following photo


Chemical like polymer pretreatment often improve solids removal effeciencies. The use of chemical flocculants with GNPIC inclined plate clarifier is depend on the efficiency of the system and so on.
