In drilling mud solids control system, pumps are used to transfer the drilling fluids from one machine to another. Submersible slurry pump is one type pump installed vertically on mud tank or mud pit. In GN designed solids control system, this type slurry pump is often used in HDD project and feeding to centrifuge wherever it is used.
Submersible pump used in HDD mud system
GN has standard model of HDD mud system ranging from 200GPM to 1500GPM. All the models are compact structure. The used drilling fluid in this horizontal drilling comes out from the drilling hole and accumulates in a mud pit. It requests a pump to transfer the drilling mud to the mud system. Above picture perfectly shows the how the submersible slurry pump is installed vertically on the mud pit to transfer the drilling mud to the shale shaker in the HDD mud system. As this pump is installed out of the mud system, when making the quote to clients, GN always recommends an independent submersible slurry pump as an option.
Submersible pump used as centrifuge feeding pump
In an oil and gas drilling mud system, after treated by the de-silter cyclone, the drilling mud will be pumped to decanter centrifuge for fine solids separation. Vertically installed in mud tank will ensure a larger tank compartment capacity for more drilling mud storage.
GN’s submersible slurry pump is single stage single suction type pump that is usually used to transfer the slurry with larger solids content. There is no bearing and gland seal between impeller and pump body; hence the slurry pump is maintenance-free and high temperature resistance. Submersible slurry pump is an ideal equipment to transfer the mud to centrifuge and HDD shale shaker. Besides, it can also be used to feed the de-sander and de-silter.
