There are generally three types of pump losses: hydraulic, volumetric, and mechanical. Hydraulic loss, also known as flow loss, is the difference between the theoretical lift and the actual lift. It includes three aspects. (1) Since the actual number of impeller blades is not infinite, the liquid does not flow strictly along the blade's orbit, and circulation occurs to produce eddy current loss; (2) resistance loss; and (3) impact loss. Volume loss is the energy loss caused by the flow...

Due to the structure of the displacement limit, it is generally considered gear pump can only be used as a constant flow hydraulic source. However, the attachment and threaded coupling valve scheme is effective in increasing its functionality, reducing system costs and increasing system reliability, and as a result, gear pump performance can approach that of costly, complex piston pumps. For example, installing a control valve directly on the pump controls the cost by eliminating piping between...
