Recently a unit of mute solids vacuum pump are ready for shipment, it will be used for tunneling slurry transfer. The vacuum pump is used to suck the slurry used for Tunneling project and discharge to another place, the max suction distance is 50m horizontally, max discharge distance is up to 1000m horizontally. The vertical lifting depth is up to different materials. The max solids content allowed is 80%, and max solids size can be pumped is up to 75mm, it can be used to transfer tunneling slurry, especially for long distance transfer. Since the vacuum pump is 100% air operated pump, no need electricity supply, it is suitable for hazardous area application. When the vacuum pump is installed near city center, a mute tank is applied to reduce the noise.

Tunneling slurry is a mixture of topsoil, Portland cement, and water. The consistency of the slurry is different depending on its purpose in a repair project. The slurry is made thinner and more watery for filling purposes and thicker with less water for lifting purposes. In foundation repair and tunneling, slurry is used as a filling material and is of a thinner consistency.

We have 3 models of solids vacuum pump for option with different flow rate, GNSP-10B with flow rate max 10m3/h, GNSP-20B with max flow rate 20m3/h, GNSP-40B with max flow rate 40m3/h. There are automatic mode working and manual mode working for option based on different working conditions. After several times testing for suction time and discharge time, the user can adjust the timers of suction and discharge until it reach your requirement.
It can be widely used to transfer waste mud, drilling cuttings, oil sludge, tunneling slurry, animal waste, hazardous waste, sand and solids, etc. material. If you need solids vacuum pump, pls contact GN solids control.
