A hydraulic gear pump is a positive displacement pump that converts mechanical energy into hydraulic energy by transferring hydraulic fluid using meshing gears. Driven by an engine or motor, the rotating gears create a vacuum, drawing fluid into the pump. The fluid is then trapped between the gear teeth and carried to the outlet, where it is discharged under pressure. These compact, fixed-displacement pumps are simple, durable, and commonly used in various hydraulic systems for their consistent performance and relatively low cost.

A Boss Hydraulic Gear Pump is a type of external gear pump known for its efficiency and versatility across various applications. It features a cast iron or aluminum housing and offers options for SAE or European flange mounting, along with various inlet/outlet port configurations. These pumps are designed for high-pressure applications, with a working pressure of up to 250 bar (3625 PSI) and speed ranges from 500 to 4000 RPM. 

The HM2021 Hydraulic Pump is typically a gear pump designed for heavy-duty applications such as wheel loaders, with a flow rate often exceeding 70 LPM. While specific brands vary, it is a component that converts mechanical energy into hydraulic power to operate machinery. Key characteristics include its use as a rotary pump, often featuring a cast iron or aluminum body, and a power source that can be AC powered or connected to a transmission.

Parker hydraulic gear pumps are a type of positive displacement pump that use meshing gears to transfer fluid from the inlet to the outlet. They are known for their rugged design, efficiency, and cost-effectiveness, making them suitable for a wide range of mobile and industrial applications. Parker offers various gear pump series, including the PGP/PGM 500 series, which are designed for high-pressure applications. These pumps can be fixed or variable displacement and are available with different mounting configurations.
