■ Summary
The JQB5×6-10 Shear Pump generation is uniquely design pump for shearing polymers and clays. To improve the drill fluid properties, the polymers or clays should be highly sheared before adding to the drill fluid system, If not sheered, the polymers maybe jam the strainer and will result in losing amount of polymer and increasing drilling costs, and the large-size solids in the drill fluid will harden and difficult to clear away as well. The JQB5×6-10 shear pump has proven best for applying the high shear necessary to hydrate polymers and clays and to their best properties. Using the JQB5×6-10 Shear Pump reduces the bentonite clay needed by 33% or more and polymer needed by 15% or more. It also improves fluid loss and filter cake, builds gel strength, and low shear rate viscosity to better hold up solids. With reliable shaft seal structure and more convenient in operation and maintenance, it comes up to advanced world standards in the same products.

■ Principle of Operation
●The JQB5×6-10 shear pump adopts a set of compound seal for no leakage at stuffing box. Inside pump is a 300series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty(50)% of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, OSHA type belt guard and a 75HP(55KW)1800RPM EXPLON PEROOF U/L approved electric motor, 460 volt, 3 phase 60 cycle. Included is a special hopper(ZHP150) with nozzle sized for this application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved shaft seal.
There are many principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your JQB5×6-10 turbine shear pump.
This document will deal with both general and specific recommendations for improved JQB5×6-10 turbine shear performance in both oilfield and industrial applications.
Warning: This pump can not be used on active mud system since it will shear drill solids and barite, these solids will also damage pump very quickly.
