Vacuum pumps are also called solids pumps or slurry pumps. Comparing with other pumps, the most significant character of a vacuum pump is the driven mode. A vacuum pump doesn’t need electricity to operate, instead, it can be air driven. GN Solids Control has put into market the vacuum pumps for years, and GN Vacuum Pumps are widely used in various applications in many countries.

Just recently, a client from Europe purchased 2 sets of vacuum pumps from GN Solids Control and those vacuum pumps are to be air shipped to their mining jobsite in next week. They purchased 2 different models, with a bit differences in specification.

1. GNSP-40B this is the largest model of GN Vacuum pumps, which can suck the material from 50 meters distance and discharge to around 1000 meters away. It is quite powerful. And the pipe diameter of this GNSP-40B is quite large as large as 75mm, in this case, it can transfer sands and small stones, for example, the materials in a mining industry. A powerful pump as GNSP-40B of course will consume a large power. It need an air consumption of 600 CFM.

And it is large in size, too, with a cubic shaped frame.

2. GNSP-20B is a smaller vacuum pump comparing with GNSP-40B, and it is also a middle size model among GN vacuum pumps, comparing with GNSP-40B, the GNSP-20B is smaller in size and moveable designed with 3 wheels. It can suck material from 50 meters and discharge to 500 meters. Its air consumption is half of the GNSP-40B. It is the most popular model, too.

For this project, the client purchased both models to have a flexible usage in the mining site. Besides, the GNSP-40B and GNSP-20B can share the same hoses for sucking and discharging.
