GPY-2A Hydralic Gear Pump

Key Performance Parameters

GPY-2A is a compact external gear pump with a displacement range of 2–12 cc/rev. It operates at a rated pressure of 16–21 MPa, with a maximum pressure up to 25 MPa. The working speed is typically 800–3000 rpm, and the maximum speed can reach 4000–5000 rpm.

It supports both clockwise and counter-clockwise rotation, with volumetric efficiency ≥90%, ensuring stable and efficient output. The pump uses standard hydraulic oil and works within a temperature range of -20°C to +80°C.

Featuring flange mounting, optional key or spline shaft, and an aluminum or cast iron body, it is lightweight, durable, and designed for low-noise operation.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
