10) The electric motor and control panel can be with different explosion proof standard for option, like CNEX zone 1, ATEX zone 1 or IEC EX zone 1.
11) The bearing to be used is from world famous brand bearing for longer working life.

12) Suitable for high solids content cuttings, big solids size, less flowrablity
When the rod chambers at the front ends of the two oil cylinders are connected by high-pressure hoses, the rod chambers at the front ends of the pistons of the two oil cylinders are connected through an oil pipe to form a closed oil path. The rodless cavity connects the rodless cavity of the two cylinders with the main oil pump and the mailbox through the reversing valve. For more information, pls contact GN freely.

Recently we shipped one unit of containerized chemical dosing system for dewatering centrifuge to our client in Africa, this is repeat order from one of our old client. The technical configuration is as below:

The three tank automatical powder polymer mixing system, including 3 compartment tank, auger conveyor, hopper, 3 sets agitator, level meter, solenoid valve, piping system, flow meter and PLC control system for automatic continuous operation, 2 sets of chemical dosing pump, 2 sets safety valve, pressure gauge and pump holder, etc.
Coagulant mixing tank including agitator, level meter, 2 sets of chemical dosing pump, safety valve, pressure gauge, pump holder, etc.
All of these above items are installed inside 20ft container, with windows, doors, lightings and air conditioner.

The dewatering unit worked with dewatering centrifuge, as one of professional decanter centrifuge manufacturer in China, GN solids control produce various size decanter centrifuge from 9 inch bowl, 14 inch bowl, 18 inch bowl, 22 inch bowl, 30 inch bowl, with different bowl length for different applications. The client already purchased the dewatering centrifuge before, when the treated fluids/ mud will be recovery for reuse, only mechanical separation will be enough, cause the decanter centrifuge cut point is 2~ 5 microns, which can separate most of the fine solids from the mud/drilling waste. When the drilling project is finished and the purpose is to get pure water and final disposal, we need to use dewatering unit ( into the container) to get the ultra fine solids to be accumulated into the particles which can be treated by decanter centrifuge. The discharged water remained solids only below 1 microns, most of the solids can be separated out, the discharged solids is dry enough to be collected by waste truck.
