Recently 2 units of vacuum loading solids transfer pump are shipped to Europe client. One model is GNSP-40B, another model is GNSP-20B, the working principal of them are same, just a little different in outlook.


GNSP-40B vacuum pump is the biggest model right now, the designed capacity is 40 m3/h, which can allow max solids size is 75mm, the required pressure is 550 Kpa ~ 785Kpa ( 80 ~114 PSI),min air demand is 17m3/min ( 600CFM), the max solids content allowed is 80% , max discharge distance is 1000m in horizontal, max suction distance is 50m in horizontal, for vertical suction and discharge height, it will depends on the material conditions, we will negotiate this with the customer. The pump is in a frame for convenient lifting and transportation.
GNSP-20B vacuum pump is a mobile design vacuum pump, with 3 wheels for movement in short distance, the compact footprint compared with GNSP-40B. the designed treating capacity is 20 m3/h, which can allow max solids size is 50mm, the required pressure is 550 Kpa ~ 690Kpa ( 80 ~100 PSI),min air demand is 8 m3/min ( 280CFM), the max solids content allowed is 80% , max discharge distance is 1000m in horizontal, max suction distance is 50m in horizontal, for vertical suction and discharge height, it will depends on the material conditions, we will negotiate this with the customer.


GN vacuum pump can be applied for many different industries for material transfer, such as drilling mud transfer, animal waste, oil sludge, tank bottom sludge, waste mud and waste solids transfer, silo transfer, sand transfer, vessel bottom clean out, and other kinds of slurry transfer.
Based on different project requirement, the user can select different model vacuum pump for their project. When compact footprint is required due to space limit, we will select small vacuum pump.
