Shear Pump

Description

The BB shear pump reduces the cost of mixing polymers and clays while improving mud properties. Shearing the polymers eliminates fish eyes and prevents polymer chaining (long strings), which cannot pass through the shaker screens, the BB 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.

BB Shear Pump Impeller and shell are made of high wear resistant cast irons, with longer servicing life. The shear pump shaft has high strength that can bear certain load, reducing shafts deflection and extending seals service life; the shaft is lubricated with lubricants and lubricating grease and the oil seal is made of special structure and materials, suitable for high and low temperatures and complicated environments; front opening structure is used for convenient installation, repair and maintenance.

Features & Benefits

1. Maintain and enhance the excellent hydration effect of bentonite particles. Shearing pumps effectively accelerate the dispersion of bentonite to increase the surface contact area and ion exchange frequency of the particles, thereby to generate a better hydration velocity and drilling fluid rheological property. Particularly for offshore drilling with sea water drilling fluid.

2. Speed up the dilution and hydration of polymer chemicals.

Prior to entering into the drilling fluid, polymer is chopped and reduced in size with ideal efficiency to keep polymer particles perfectly contact with water, finally to accelerate the dissolving, dispersion and hydration process. Using shear pump to treat the drilling fluid is favorable for increasing drilling operation, improving quality of drilling fluid, reducing the drilling cost and time, and reducing the labor intensity.
