The choice depends on the system handling capacity, for example, if there is a 3K oil well drilling mud solids control system holding 120m3/h capacity, the mud mixing pump will also need capacity up to120m3/h. Then thecentrifugal pump should have flow rate up to 120m3/h.

| JET MUD MIXER |
Usually, the mixing pump selection has correlation with flow rate, the horse power, the design of system as well as the tank construction
Then we need to take the tank storage capacity into consideration. And the jet mud mixer should finish mixture capacity up to storage capacity every 10-30 minutes.
In oil gas drilling solids control, shear pump can shear polymer and clay in the drilling fluid, which then enter into circulating tank and accept the next process to change the present status of drilling fluid and improve the performance in compliance with the request of oil drilling.

| SHEAR PUMP |
Once drilling fluid can’t be fully sheared, polymer maybe block shaker screen in first circulation to lose large polymer, increase drilling cost and make the large size solid phase particles hard and difficult to eliminate.
Shear pump is developed on the basis of existing centrifugal pump theory via some improvement to develop a new and efficient centrifugal pump. It is designed for quick preparation and disposal of drilling fluids in the solids control system. The main application is to shear polymer clay, it can mix materials effectively, fully hydrate materials, save materials, shorten drilling fluids preparation time, supply good drilling fluids performance to drilling operations.
