Why Is the Single-Acting Vane Pump Called a Non-Unloading Pump
Core Reason: Permanent Eccentricity In a standard single-acting vane pump: The cam ring and rotor maintain fixed eccentricity Pump displacement remains constant Flow is continuously delivered during rotation There is no built-in pressure unloading path Therefore, the pump does not automatically unload under pressure, so it is called a non-unloading vane pump.

Oil Trapping in Gear Pumps： Causes & Effects in Hydraulic Systems
1.What Is Oil Trapping? Oil trapping occurs when a small volume of hydraulic fluid becomes sealed between meshing gear teeth during rotation. As the gears continue to rotate, this trapped oil has no direct flow path to the inlet or outlet. 2.How Does Oil Trapping Occur in Gear Pumps? Two gear teeth come into full […]
