Hydraulic gear pump:

Hydraulic gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to deliver liquid or pressurize it. The structure of an external meshing double gear pump consists of a pair of mutually meshing gears and pump cylinders that separate the suction and discharge cavities. When the gear rotates, the volume between the teeth at the mutual separation of the suction cavity side teeth gradually increases, the pressure decreases, and the liquid enters the teeth under the pressure difference. Axial piston pump: An axial piston pump works by utilizing the volume changes generated by the reciprocating movement of the plunger parallel to the transmission shaft in the plunger hole. Due to the fact that the plunger and plunger hole are circular parts that can achieve a high precision fit during processing, the volumetric efficiency is high.
