Adopting asymmetric toothed double-module gears, axial automatic compensation structure, radial hydraulic balance, to ensure that the pump has high volumetric efficiency and high reliability.

Adopting high-strength and warm-resistant cast iron shell with strong load-bearing capacity.

Self-lubricating bearings are adopted to improve the carrying capacity of the pump.

Multiple pumps with large displacement and small displacement pumps connected in series across the series.

Input shaft coupling form can choose flat key, rectangular spline, SAE involute spline.
