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

GN solid vacuum pump is fully pneumatic conveying equipment, It is a type of pneumatic pump that sucks the material with vacuum produced by air operation, and then converts to positive pressure for discharging. Most of the solids, sludge and liquid could be transferred by using this pump. With special structure design of no rotating parts in the cavity, it can be used at tough environmental with high working performance and less maintenance.

The Capable of producing powerful suction up to 85Kpa(25 inHg). Discharge head and distance is large, clear water theoretical discharge height of 80 meters, horizontal distance is around 500 meters.

Sludge vacuum pump can be used for transport or removal Liquid with high solid content, oil sludge with high viscosity, can also be used for cleaning Handle bulk solid materials, including sand, dust, etc.

Air operation, no need electric power, suitable for hazardous area application.

Transferred solids size Maximum 50mm or 75mm, sludge solids content up to 80%.

Ecomondo – The Green Technology Expo

GN separation is very glad to inform that we will participate Ecomondo- The Green Technology Expo held in Rimini. Ecomondo is one of the most important envorimentual and sustainable exhibition in Italy.

The Ecomondo will be held in 7th to 10th November, lasting about 4 days. Ecomodo provide a platform for professionals and business worldwide to exchange, collaborate.

Ecomondo – The Green Technology Expo

Venue: Rimini Expo Centre, Italy
GN Booth: B7, 414

This time, GN will bring decanter centrifuge, solid vacuum pump and dewater screw press in Ramini.

GN decanter centrifuge can complete basic separation process such as solid-phase dewatering and liquid pahse clarification. The 3-phase decanter centrifuge can achieve solid-liquid-liquid separation. GN decanter centrifuge has shown excellent performance in the treatment of industiral wastewater, municipal, wastewater and oily sludge and other fileds, according to the different hourly capacity, we have some different model for your choose.

GN solid vacuum pump is fully pneumatic device that can handle various forms of waste, including liquid, slurries, powders, particles, viscous substance, etc. It is widely used in fields such as municipal sludge wastewater treatment.

Dewater screw press, it’s a kind of economic and environmental friendly sludge dewatering equipment. It is a new type of sludge extrusion dewatering equipment by using the principle of screw extrusion.

GN look forwrad to communicate with more professional clients at the Ecomondo exhibition. We wish to establish  connections with customers, partners to jonintly promote the development environmental protection.






Ecomondo the Green Technology Expo In Rimini

Ecomondo the Green Technology Expo will be grandly held from 7th to 10th November at Rimini expo center in Italy. The exhibition aims to showcase new technologies and equipment in solid-liquid separation in the wastewater recovery and environmental industry .

As a processional equipment manufacturer, GN separation will appear at Ecomondo Green Technology Expo with booth No. B7,414 to show decanter centrifuge, solid vacuum pump and dewater screw press.

At this exihibition, GN will show the following equipment

  1. GNLW224FT-VFD. It’s the smallest model of decanter centrifuge which we have, with bowl diameter 220mm(9 inch), the max bowl speed is 5054RPM, we adopt SUS2205 or SUS 2304 (Duplex Stainless Steel) Centrifugal Casting, in order to reduce wear and make lifespan a little longer.
  2. GNSP10B solid vacuum pump, it’s 100% pneumatic driving, need to connect a compressor for work, it can be safely used in flammable and explosive places.
  3. GNHDL14SY Mini dewater screw press, it’s widely used in sewage treatment projects of municipal, aquaculture, food, starch, oil, pharmaceutical, chemical, paper, leather and other industries.

GN Separation is looking forward to meeting new and old customers at the exhibition.
