Mud mixing hopper is important equipment to prepare and increase drilling fluids weight by adding and mixing bentonite, changing fluid density and viscosity in the whole solids control system. A 6 inch mud hopper complete with nozzle, butterfly valve, sack table, tee, venturi educator, flange all mounted on a base. Flange there is DN or ANSI standard for choose. Material can be produced to carbon steel or 345E steel to suit clients' different working conditions. Also, there is 4 inch for option. It has a more excellent operation performance if being matched with a shear pump.
Model | APMH 150 |
Inlet | 6" |
Outlet | 6" |

Generally, mud hopper is worked together with a jet mud pump. we can call it mud jet mixer. it is widely used in drilling. we can design 1 venturi mud hopper + 1 jet mud pump or 2 venturi mud hoppers + 2 jet mud pumps on one base.
Mud hopper pump capacity is defined by mud hopper size and pump. For example, the hopper including 4'' or 6'' port one. And the diameter is 400mm-700mm. For pump, the normal type for mixing hopper including APSB8X6, APSB6X5 and APSB5x4 driven by 75HP, 50HP, 30HP motor. The flow rate is about 400-1200GPM. To select proper mixing pump, please consider the flow rate of the whole mud system. Almost of clients prefer Venturi hopper to the swirl hopper because of high capacity and dust-free design. Furthermore, the Ventri hopper is more compact than swirl hopper
In almost mud system, the mixing hopper pump is set at end of mud tank. They are assembly of hopper, pump, skid. In some system, there are 2 complete set of mixing pump. That means 2 hoppers and 2 centrifugal pump. For some clients, they prefer the separated mixing skid in a frame. The hopper can be in a separated frame or just a single hopper connected with all lines input and discharge. The pipings connected with mixing pump including the input line, discharge line, some are fit with T port for convenient mud transfer among tanks and compartments
In a complete mud system, how many sets mixing pump do we need? It's depending on mud flow rate of whole system. And the mixing pump can be assembled together with shearing pump we call it jet shearing pump. Furthermore, different users prefer different configuration on mud system. The mixing pump skid can be fit only one mixing hopper pump, or 2 sets of mixing hopper pump. And usually the 2 sets of mixing pump work simultaneously for sufficient fluids productivity
Besides the oil well drilling, mud mixing pump is widely used in HDD mud recycling system. The difference is usually the HDD mud mixing pump smaller than oil drilling one.
