The shear pump can mix and hydrate fully the materials which were added into the mud, to save the usage of mud materials, shorten the
mix time and to supply good- performance mud for the drilling. It can greatly improve hydration degree of soil particle moving. JBQ
series shear pumps can save bentonite above 30%.

Shear pump is composed by impeller, volute, support, packing case, transmission shaft, pulley, combination belt and electrical
machine. The impeller of the shear pump is different with the water pump, the structure is more complex. It is the core part of the
shear pump, with high efficiency.


The impeller is made up by 5 parts: axial compressor turbine, stock solution tank, pump impeller, pressure cabin and shear plate. The
axial compressor turbine, pump impeller and stock solution tank were casted critically as a ensemble by stainless steel, the
structure is very compact.

The pump is single stage and single section of cantilever type centrifuge, it provides shearing function with guide liquid type,
centrifugal combination impeller and shearing plate. The special structure liquid end impact shearing plate, make it high speed
shear, in order to complete agitate to fluid.


In the practical production, when the single centrifugal pump can’t meet the transportation tasks, we can use the parallel and series of centrifugal pump.

The parallel

If the same model centrifugal pump is parallel and each inlet line is all the same, the flow and head of the two pumps must be respectively same, it has the same pipeline performance and the single pump performance.

The parallel operation can be used in centrifugal pump. If need the bigger flow and low head, also the flow is bigger than the flow which is produced by single pump, sometimes use two parallel centrifugal pumps meet the requirements. The two pump independent suction, then is injected the same pipeline, in order to reach the same total moving head. If the two pumps is same, export total head is equal to the head which is produced by the two pumps, the flow is the two times of the single pump. But the two centrifugal pumps can’t produce the same export head, but because the wear effect, one of the pump head will be less than the other pump. The power is produced by the greater ability pump is bigger than the other pump. So the parallel operation is not widely used.

The series

Most of the time, the single centrifugal pump can’t meet the requirements of the needing head. Using the two pumps series, the export of the before pump is as the feeding month of the after pump, it can obtains the needing head.

If the same model pump is series, the flow and head of each pumps are all the same, so in the same flow, the head of the two series pump is the second times of the single pump. when the pump is used with series, it can’ t extend the safety working limit of flange plate, otherwise, the series pump don’t need to install too close.
