Mini Solids Vacuum Pump and Mini Decanter Centrifuge for International Customer

Recently one unit of mini solids vacuum pump and mini decanter centrifuge are ready for shipment for international customer. The mini solids vacuum pump is used for tank cleaning application, the mini decanter centrifuge is used for solids liquid separation.
GN solids control can produce vacuum pump with different flow rate, we have GNSP-40B, GNSP-20B, GNSP-10B for option, also we have GNSP-05B as Mini bilge cleaning sludge vacuum pump. The technical specification is as below:


Max flow rate is 5m3/h for clear water, inlet and outlet size is 2 inch and air intake hose size is 1 inch, the vacuum degree is 85Kpa/25 inch HG( Mercury Column), the discharge head is 80m and pressure is 116PSI. The max horizontal discharge distance is 500m. The max solids content is 80%, and max solids size allowed to be sucked is 30mm.The pressure required is 550 ~ 690 Kpa and air demand is 4.3 m3/min ( 150 CFM). The mini vacuum pump can be used for the cleaning of residual waste inside the cabin and the transportation of loose materials. The higher flow rate vacuum pump can be used to transfer drilling waste, oil waste, crude oil tank bottom cleaning sludge, oil sludge, sand, contaminated soil and other sludge, especially it is 100% air operated pump which can be safely used in electricity limited area.


The mini decanter centrifuge with 9 inch centrifuge bowl, we have different models for different applications. GNLW223D baby decanter centrifuge with bowl length 26.4 inch, it can be widely used for diamond core drilling waste water treatment. If the user need a higher treating capacity and need the discharged water more clear, they can select a longer bowl length 36.4 inch, GNLW224ET-VFD.
If you need mini decanter centrifuge for solids liquid separation, pls contact with GN solids control.

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

If you required the solids vacuum pump, pls contact with GN solids engineer.

Sludge vacuum pump To India

Last Month we shipped one unit of sludge vacuum pump to India for oil sludge transfer with capacity 40m3/h. This month the client repeat order again for a smaller flow rate 20m3/h vacuum pump, they need a smaller size vacuum pump.
When the client use the vacuum pump to transfer the oil sludge or tank bottom cleaning oil sludge, the real capacity will reduce according to different material. The higher density & viscosity of the material, the less transfer capacity it will produce.
The major components of a vacuum pump including:
1) Lifting frame
2) Vacuum tank and pedestal comnination
3) Air suction combination
4) Slurry suction pipe combination
5) Slurry discharge pipe combination
6) Air jet tube components
7) Air inlet pipe combination
8) Pressure pipe combination
9) Pneumatic control box


We will suggest the user to have one set of spare parts for their operation for convenient replacement once it is required.
What other accessories is required to operate the vacuum pump?
This is also the most common questions from our clients, they need to know the operation cost to use the sludge vacuum pump. There is pressure and air volume supply requirement for different model vacuum pump. Also the user need to prepare the strong enough suction pipe and discharge pipe with suitable length as per their own requirement. Our vacuum pump is 100% air operated pump without electricity power supply, the user need to prepare for suitable model air compressor. Before purchasing, we will send the question list to our client to judge if our vacuum pump can work for their project or not, especially for the suction depth/height, suction length and discharge distance.
GNSP-40B is the largest model we can produce right now, we can make customized design if the client need to put several units one one skid, the GNSP-20B, GNSP-10B vacuum pump is portable with compact design.
