Product Overview
Model Interpretation
-
CBHZ: Product code, indicating the external meshing gear pump series of Hefei Changyuan Hydraulics.
-
F: Pressure grade, corresponding to a rated pressure of 20MPa.
-
20: Nominal displacement (unit: mL/r).
-
R: Rotation direction, meaning right-hand rotation (clockwise; left-hand rotation is marked as “L”).
Core Features
-
Adopts asymmetric tooth profile dual-module gears, effectively optimizing hydraulic performance and reducing operational noise.
-
The pump casing is made of high-strength wear-resistant cast iron, ensuring excellent load-bearing capacity and prolonged service life even under harsh working conditions.
-
Equipped with an axial clearance automatic compensation mechanism, which maintains high volumetric efficiency stably even at a low rotation speed of 400rpm.
-
Multiple input shaft connection options are available, including flat key, rectangular spline, SAE involute spline, and metric involute spline, adapting to different transmission requirements.
-
Flexible inlet and outlet connection designs: thread connection, flange connection, etc., with optional port orientations such as rear-inlet rear-outlet and rear-inlet side-outlet.
-
Integrates radial hydraulic balance technology and self-lubricating bearings, further enhancing operational reliability and load capacity.
