■ 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.
