In the oil and gas industry, slurry pumps are widely used in all aspects. For example, during drilling, slurry pumps are used to transport drilling fluid near the drill bit, scour rock formations and remove cuttings. In the field development process, slurry pumps are used to transport slurry containing reservoir material and maintain well pressure to increase production. In the process of natural gas transportation, slurry pumps are used to mix water containing natural gas particles into a slurry to reduce friction and improve transportation efficiency.
