In drilling mud system, shear pump is one kind of centrifugal pump. It includes overhead belt, and centrifugal pump. Furthermore, some of oil drilling shearing pump will include venturi hopper, overhead belt and centrifugal pump assembly.

Drilling fluid shear pump is a special purpose equipment of solids control system which can meet all customers’ requirements of preparing drilling fluids for the well drilling. This Drilling Mud Shear Pump manufactured by KOSUN is used to treat the high property mud, make the mud obtain good rheological properties and cut the drilling cost as much as possible. Shear pump is also called shearing pump, which is a centrifugal pump, but used for shearing of drilling mud chemicals, shearing the bentonite. The shear pump reduces the cost of mixing polymers and clays while improving mud properties. Shearing the polymers eliminates fish eyes and prevents polymer chaining, which can't pass through the shaker screen. Shear pump is available as a belt-driven or diesel-driven package including a hopper, mud gun and transfer line orifice plate. A complete system with skid, tanks, and piping are also available. Shear Pump is a new design for clients, that is used to quickly configure and treat drilling mud, can satisfy clients’ requirement of configuring high performance mud. Shear pump can effective mix and hydrate chemical material, save mud materials and shorten configuration time.
 

Drilling fluids shear pump applies axial suction structure, consisting of motor, pump seat, pump shell, impeller, shearing impeller and other components. Belt and mechanical compound seal guarantee no leakage. There is a stainless turbine inside ( which composes entrance bucket, main impeller, nozzle, catch compartment ) and a shear pump.

The Benefits of KOSUN Shear Pump for Drilling Mud Configuration

1. Adopts the unique research and development of mechanical seal technology, novel and unique design at home and abroad, the seal performance is advanced, reliable operation and long service life.

2. Greatly improves bentonite particles hydration degree, reduces the bentonite clay need by 30%.

3. For polymer or clay, rapid hydration provides high shear force, solving polymer ( or clay ) in the drilling fluids that hydration is bad and prominent problems.

4. It also reduces the mud cake and fluid loss, reduces drilling fluids shear rate, improves the gel strength, so as to achieve the advanced international level.
