The full hydraulic drive system is used for high temperature ambient for heavy mud with flexible bowl and differential speed.
1 unit of GNSP-20B vacuum pump with max transfer capacity 20m3/h
1 unit of GNSP-40B vacuum pump with max transfer capacity 40m3/h
Working principal of sludge vacuum pump is as below:
- Material suction: high pressure air gets into the inlet air tube, high vacuum is produced in the vessel, when the pressure inner tank is lower than ambient pressure, the sludge material is sucked into the tank. When suction process is finished, the compressed air flow direction changes and gets into the material storage tank.
- Material discharge: When the pressure inside tank became higher than ambient pressure, the sludge material will be discharged out. The max horizontal discharge distance is 1000m for GNSP-40B vacuum pump, the max suction distance is 50m, the vacuum pump can transfer material with max solids content up to 80%, the max allowed solids size is 75mm. the air compressor is required to supply air flow to vacuum pump working, the pressure request is 550 Kpa to 785 Kpa ( 80 ~ 114PSI), air demand is 17m3/min (600CFM).
The vacuum pump can be used to transfer waste mud, waste solids ( drilling cuttings), drilling fluids, sand, oil sludge , tank bottom cleaning sludge, vessel bottom clean out, waste pit cleaning, animal waste, etc.
