GNSB centrifuge pump manufactured by GN Solids America LLC is the mud feeding machinery for solid control equipment in drilling mud system.

Pump installation

Pump installation location should be near to the source and purposely to shorten the length of the suction period and prevent the suction loss. Pump installed base should be leveled, firm and secured in order to avoid vibration during operation.

Coupling installation

The pump and motor for a long use life depends on the elastic coupling. Available steel straightedge by coupling the up and down or so, with the view straightedge and coupling the garden all parties should contact closely. Namely coupling outside garden parties should be in a straight line to make sure that the motor shaft and pump shaft coaxial angle.

Entrance pipeline installation

Entrance piping shall be in accordance with the pump inlet matching.

Suction piping not allowed to install throttle valve, but can be installed normally open valve to reduce fluid flow disorder. To avoid suction people line produced in steam bubble, the pumping source and between pump from high to low gradually transition. If users need to pump in use suction conditions, use vacuum pump or bottom valve pilot.

Pump at the entrance line must be flat; the length of at least two times the diameter of the inlet line.

Exit line

In order to facilitate pump maintenance, the exit pipeline should be installed normally with open valve.

All line (including population line) must have their own support.

When work condition is unknown or unstable, export in pipeline must be installed throttle valve in order to ensure the pump in the design point operation.

When the pump discharge and pressure equipment connected, the throttle valve and pump must install a check valve to prevent the liquid reflux, otherwise, the return fluid can lead to damage.

Desilter Hydrocyclones

Desilter Hydrocyclones

Mud Cleaner is a combination of desander cone, desilter cone and bottom shaker with compact structure. It is called the 2nd and 3rd phase solids control equipment.

Optimal performance of hydrocyclones requires a proper balance of feed head, feed rate (GPM), and apex opening. Improper balance of any of these variables can adversely affect performance.

Mud cleaner

In normal operation, feed slurry is introduced tangentially into the interior of the hydrocyclone at high velocity causing a whirlpool effect to occur inside the cone. The swirling motion of the slurry drives the larger, denser particles outward against the cone wall while the smaller, lighter particles move toward the center of the cone.

GN also have feeding pump for desander and desilter available ,main spare parts are interchangeable with Mission pump.For more information,pls contact us

The hopper design along with the venturi mixer ensures that clogging and build up of chemicals is avoided. Upstream of the mixing eductor a stream is diverted to a radial premixer above the mixer inlet. Powder chemicals are pre-wetted in the radial pre-mixer before entering the venture stream in the eductor, thus eliminating “fish-eyes” and microgels.

A mud-flow device, also called a jet hopper, in which materials are put into the circulating mud system. The mud hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle (jet) below the conical-shaped hopper. Dry materials are added through the mud hopper to provide dispersion, rapid hydration and uniform mixing. Liquids are sometimes fed into the mud by a hose placed in the hopper.

Mud hopper

GNSL series Jet Mud mixer is special equipment to prepare and increase the drilling fluids weight by adding and mixing  bentonite, change the fluid density, change the mud density, viscosity, and dehydration. The effect is more prominent matching with Shear Pump. GNSL jet mud mixer is a unit used together with the solids control system for petroleum drilling and horizontal directional drilling(HDD). The unit includes one sand pump, one jet mixing hopper and one jet mixer that are installed in a base with pipe valves. It is safe and stable and can be moved conveniently. At the same time,we can make Twin-Jet Mud Mixer according to the user requirements.It is designed by GN solids control bentonite mud mixer,drilling mud tank jet mixer.

GN can assist with properly sizing a hopper to fit your system.  There is no reason to be forced to mount the hopper on top of the mud tanks since the jet-venturi allows for convenient location of the hopper.  Sizing assistance should be requested when extensive piping or elevation is planned for the downstream side of the hopper.
