GN Solids Vacuum Pump sold for offshore drilling platform

Recently one batch of solids vacuum pump are shipped to offshore drilling platform, it can be used to transfer drilling cuttings ( drilling waste), clean the cabin, clean the drilling platform, clean the mud tank, etc. It is an ideal equipment to transfer slurry with high content solids, high density, high viscosity.


We have 3 models of solids vacuum pump with nominal transfer rate of 40m3/h, 20m3/h, 10m3/h, the capacity will be varied for different material. For the max model GNSP-40B vacuum pump, the max suction distance is 50, the max discharge distance is 1000m, and max transfer solids content is 80%, the max allowed solids size is 75mm. The user need to prepare a air compressor for air supply to the vacuum pump, the air demand is 17m3/min. There are 2 mode for option, automatic and manual, for normal condition, automatic option will be selected, for special material and special working condition, the user can choose manual operation.
The smaller size vacuum pump is compact design and moveable design. The max solids size is 50mm, the max discharge distance is 500m, and air demand is 8m3/min and 4.2 m3/min.
Except for solids vacuum pump, we also provide other types transfer pump, like centrifugal pump, submersible slurry pump, shear pump, screw pump, etc. Compared with these pumps, the vacuum pump’s design is more compact, no need to use electricity, less power consumption, can transfer longer distance. Especially for offshore drilling platform, electricity power is limited to be used, vacuum pump is an ideal way to transfer drilling cuttings compared with screw conveyor and other types pump, just the user need to do small changes on the design to make it suitable for offshore drilling platform application.

Oil sludge treatment system is ready for shipment to Oilfield Environmental Solutions Company

Recently one set of oil sludge treatment system is ready for shipment to a oilfield environmental solutions company with customized painting color. GN solids control can design and produce standard oil sludge treatment system with different treating capacity 1m3/h, 5m3/h, 15m3/h, also we can design as per client’s concept and technics process.


A standard oil sludge treatment system is consist of the modular below:

  1. Waste transfer unit: GN use our own solids vacuum pump to transfer the oil sludge from the waste pit to pre-mixing modular. The features of vacuum pump: (1)100% air operated pump without using electricity power, need air compressor for air supply. The user need to prepare one air compressor to provide air for both vacuum pump and the positive pressurized VFD control panel of the decanter centrifuge.
    (2) can be adopted to different types of oil sludge, heavy duty for continuously working

  2. (3) automatically and manually working for option for different requirement
    (4) max discharge distance is up to 1000m, max suction distance is 50m, it can used into the crude oil tank without labors in, it is user friendly pump to transfer the oil sludge out of the crude oil tank bottom.
    2 pre-mixing modular: including a pre-mixing tank equipped with heating lines inside the tank wall, when the user supply hot steam to the heating lines, the oil sludge will be heat to 60 degree for easier separation in the next separation step. Mud agitator with control panel to agitate the oil sludge with necessary chemicals and keep it flowable. The submersible slurry pump will transfer the pre-mixing oil sludge to the next process- coarse solids separation modular.
    3 coarse solids separation modular: it might be removed depends on if there is coarse solids in the oil sludge.
  3. fine solids separation modular for solids/ liquid separation by using VFD decanter centrifuge, and working together with chemical dosing system
  4. 3 phase centrifuge modular to separate oil from water.

Solids Vacuum Pump manufacturer in China

Recently one batch of solids vacuum pump are shipped to Africa. As the most professional solids vacuum pump manufacturer in China, GN solids control can produce 3 models vacuum pump with different treating capacity for different applications. We have 3 models vacuum pump for option: GNSP-40B with max flow rate 40m3/h, GNSP-20B with max flow rate 20m3/h, GNSP-10B with flow rate 10m3/h.


The vacuum pump is 100% air operated pump to transfer different materials, including:
1) Waste mud/ cuttings discharged from shale shaker, mud cleaner, decanter centrifuge
2) Drilling fluids
3) Oil sludge, oil tank bottom waste sludge
4) Dredging slurry/ mining tailings/ industrial waste mud
5) Barge holdings and vessel bottom cleaning
6) Sand, solids, fine silt, coarse solids
7) Hazardous waste/ oil contaminated earth
8) Animal waste


The GNSP-10B, GNSP-20B vacuum pump are all made as portable design for convenient movement, the actual flow rate will vary based on different materials transfer, for example, the flow rate to transfer oil sludge with high viscosity and to transfer normal sludge is very different. The user need to prepare air compressor for air supply and provide enough pressure. Also the client need to prepare proper length suction and discharge pipe to connect with the solids vacuum pump. The solids vacuum pump is the ideal equipment to transfer the solids with the most compact size without electricity power supply required.
GNSP-40B vacuum pump can be put on the trailer/ truck for convenient transportation.

Air supply demand:
For GNSP-40B, 17m3/min( 600CFM)
For GNSP-20B, 8m3/min( 280CFM)
For GNSP-10B, 4.3m3/min(150CFM)

Pressure required:
For GNSP-40B, 80 ~114 PSI
For GNSP-20B, 80 ~100 PSI
For GNSP-10B, 80 ~100 PSI

Max suction distance and discharge distance:
For GNSP-40B, 50m / 1000m
For GNSP-20B, 50m / 500m
For GNSP-10B, 50m / 500m
