FAQ:

1. Key Features & Design Advantages

The PGZ series pumps are engineered with several notable features:

• High Working Pressure: Capable of operating at continuous pressures up to 350 bar, making them suitable for high-pressure systems.

• Low Noise and Low Pulsation: Advanced design and manufacturing techniques result in exceptionally quiet operation and minimal flow pulsation, contributing to smoother system performance.

• High Efficiency with Gap Compensation: The pumps feature sealing gap compensation. This design ensures high volumetric efficiency, even at low speeds or when handling low-viscosity fluids.

• Broad Operating Range: They are suitable for a wide range of fluid viscosities and operational speeds, providing flexibility across various applications.

• Modularity and Combination Capability: Different sizes and displacements within the series can be combined flexibly. Furthermore, PGZ pumps can be configured in multi-pump arrangements (e.g., double pumps) not only with other PGZ units but also with other pump types like internal gear (PGH series), vane, and axial piston pumps, creating compact and powerful hydraulic power units.

• Durability and Contamination Tolerance: The robust design offers high resistance to oil contamination, which contributes to a long operational service life.
