Shear pump is the pump that do shearing polymers and clays.  The purpose of this pump is to add improvement of the drilling properties, the polymers and clays need to be sheared in great details before add back of system of drill fluid.  The polymers might jam the strainer if not sheared.  If jamming happen, it will increase the cost of drilling and larger size solids in the drilling will be turn from soft to hard  and will be difficult to clear away. The velocity, or speed of the fluid flow at outside diameter of the rotor are higher than center of the rotor’s velocity.  it is the difference of the velocity that creates shear.

The main design factor is the diameter of the rotor and its turning speed. The distance between the rotor and the stator, the time in the mixer, and the number of the generators are consider factor. Variables include the number of rows of teeth, their angle, and the width of the openings between teeth.

Shear pump is proven for applying the high shear to necessary hydrate polymers and clays.  It reduces the bentonite clay and polymer.  It is also improve loss of fluid and cake filter and build strength of gel.  The low shear rate viscosity holds up solids better.  The dependable seal of shaft adds more convenient in operation and maintenance.

The operation principle adopts mechanical seal sets for no leakage at the stuffing box.  The stainless steel turbine contain nozzles and shear plate and fluid is sheared through the pump.

Base on the demand of the drilling project and goal to achieve, the pump application and installation can be very.  The design of pump, if follow properly, will further improve the performance of the shear pump that shearing polymers and clays.

Please consult GN Solids America LLC’s sale staff on your shear pump inquiry.

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.

WEFTEC 2017 was held in Chicago from Oct. 2-4. As the largest water treatment show in North America, WEFTEC attracted many experts, technicians and business staff in the water treatment industry from all around the world to Chicago to share technical idea and the past experience and development for the water treatment industry.
GN solids control is a fast growing manufacturer for the separation equipment. Most of the equipment are used in the water treatment and separation area to improve the water quality and meet the environmental requirement. This year, GN Solids America exhibited its 223 decanter centrifuge and 752 shale shaker. These two mini equipment mostly used in the mining industry. Though it’s the first time for GN appearing in the show, it do attract may attention from the visitors.

Screen for Mongoose Shaker 2
After many year’s development, GN’s decanter centrifuge has become a very mature product and many customers from the industry like it very much. The material of the bowl is made of the 2205 stainless steel which is very high grade and tough. The material in the liquid and solid discharge port is tungsten carbide, this material also can make the equipment tough and endurable. It needs less maintenance and saves the operators operation cost. The bearing is provided by famous brand SKF. The decanter centrifuge can separate the solid size from 2 to 5 microns. And the variable speed equipment is controlled by VFD system which means the processing speed and capacity could be changed according to the operator’s needs when it’s in operation. One more advantage about this decanter centrifuge is that the footprint is very compact and can work in very narrow space, and very flexible to move in the remote area.

The other equipment GN showed is the mini shale shaker, usually the G force is about 7.5G. GN can also customize the configuration according to customer’s requirement. GN also manufactures the shale shaker screen. Now GN can manufacture both its own OEM screen, and also can manufacture all the famous replacement screens, from API 10 to 400. GN’s screens are upgraded to the advanced composite frame. Welcome to inquire from us for more details.
GN was very glad to meet you in Chicago. If you want to know more about GN’s product, please log on to www.gnsolidsamerica.com or you can send your inquiries to [email protected]
