The present invention generally relates to an abrasive particles injection system. In one aspect, a high pressure solids pump for use in an abrasive particles injection system is provided. The high pressure solids pump includes a pump body having a chamber with an inlet and an outlet. The high pressure solids pump further includes a first valve connected to the inlet for allowing abrasive particles to enter the chamber. The high pressure solids pump also includes a second valve connected to the outlet for allowing pressurized abrasive particles to exit the chamber. Additionally, the high pressure solids pump includes a piston member movable within the chamber of the pump body, wherein the piston member is configured to pressurize the abrasive particles. In another aspect, a method of injecting abrasive particles into a high pressure line is provided. |
