GN Mute Solids Vacuum Pump for Tunneling Slurry Transfer
GN Solids Control has been manufacturing vacuum transfer pumps for many years, and this week GN Solids Control shipped one newly developed mute solids vacuum pump to a tunneling slurry contractor.
GN Solids Control is the leading solids and liquid separation and transfer manufacturer in China with 3 manfuacturing plants. GN Solids Control is certified by API, HSE, CE, ISO 9001 etc together with many other certificates or rewards. Until now, GN Solids Control has been providing solids control equipment like shaker, decanter, desilter, desander, centrifugal pump, submersible pump, vaccum pump to over ninty countries and regions.
As for this mute solids vacuum pump, GN Solids Control engineer when made the design, put it in a mute shell to cover the whole solids transfer vacuum pump. As when the vacuum pump is working, there are two main air valves to control the on and off where noise are made. But with such special design, GN Solids Control vacuum pump will work pretty quitely even during the suction and discharge of the materials.
Inside the shell, one 40B model vacuum pump with a supporting skid is fixed inside. GNSP40B is the largest model that GN builds. Another two models 10B and 20B are easy to move with by wheels.
During working, an air compressor is used to provide the driven force for the vacuum pump. Usually the working height from the suction point to the pump inlet should within 8 meters. To have a better transfer efficiency, one air storage tank can be also used to provide a constant air.
TBM slurry treating and mud transfer is one market for GN Solids Control. Besides the vacuum pump, GN Soilds Control also manufactures some other treating equipment like TBM slurry treating plant composed by desander, desitler or long coarse vibrating screens and decanter centrifuges. Slurry canbe reused in the TBM contracting after treated by GN TBM plant.
