solids vacuum pump

Mini solids vacuum pump and mini shaker are ready for shipment to South America customer. The mini solids vacuum pump is designed convenient movable for flexible operation. There are automatic mode or manual mode for user’s selection. If automatic mode is selected, running the vacuum pump for several loops then set the timer according to the experience to fit the material condition, the running time can be adjusted and controlled by 2 pneumatic timers. If manual mode is selected, the user need to discharge empty the cavity manually. Before delivery, the timers are set at 10s suction and 10s discharge. If the cavity is full very quickly, just reduce the suction time. Conversely, longer the suction time.
The working procedure when manual mode is selected.

Connect to air supply and select manual mode.

Switch the knob to discharge position to empty the cavity.

Put suction inlet pipe into the material, switch the knob to suction position.

If cavity is almost full, switch the knob to discharge position again.
The mini vacuum pump can be used to transfer material with high solids content, and it can be used to transfer powder material such as sand, dust. It also can be used to clean fluids from drill floor, decks, pipe racks, mud rooms and drains, tanks and mud spill.


The mini shale shaker model number is GNZS752-DZ, the screen panel is 2pcs , and screen size is 750x900mm, screen area is 1.35m2, which is drived by 2ea 1.0KW vibration motor. The G force is adjustable and up to 7.5G, the deck angle is +2º. Polyurethane material screen or composite material frame shaker screen can be installed on the shale shaker. The mini shaker is widely used to separate solids from liquid by using different mesh size shaker screen.

Linear motion shale shaker with ViST screen, ViST vacuum screen technology is to work together with shale shaker, the function is to reduce drilling waste and recycle drilling fluids. In a result, ViST maximize the recycled drilling fluids volume and generates dryer cuttings. By applied with ViST, the user can save money for drilling fluids and waste management.

Decanter Centrifuge, GN produced decanter centrifuge can be applied to waste water treatment, solids control system drilling fluids treatment, drilling waste treatment, oil waste treatment and other solids liquid separation projects. We can produce decanter centrifuge from 9 inch to 30 inch bowl diameter, according to client’s requirement, we can produce fixed speed or variable frequency drive control panel.

Vertical cuttings dryer, one of the most popular model is GNCD930 vertical cuttings dryer, the lastest version is G version, we have updated the design according to user’s feedback and technology improvement.

Solids vacuum pump, the 100% air operated vacuum pump can be used at hazardous area and electricity limited area. The compact design of the vacuum pump allowed it to be installed inside the oil tank for easier picking up of the oil sludge from tank bottom, without needing people entry. The solids vacuum pump can transfer different kinds of materials, such as dredging slurry, oil sludge, material with solids content up to 80%, material with big solids up to 75mm.
Welcome to meet us at CIPPE.

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.

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.
For more information about our solids vacuum pump, pls contact with GN solids control.

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.
