Features:

① Compact and lightweight, easy to use, and high working pressure

② Single-stage pumping station: Simple structure, capable of achieving higher output pressure

③ Two-stage pump station: During low-pressure empty stroke filling, both high and low-pressure pumps supply oil simultaneously, achieving a larger output flow. During high-pressure operation, the low-pressure pump returns oil without load automatically through the unloading overflow valve, reducing power consumption.

④ Pressure Holding Function: Under the condition of no leakage in the external oil circuit, the pressure outlet is connected to a Φ63X200 oil cylinder. Upon reaching the rated pressure, the pump is stopped and the pressure holding is timed for 3 minutes, with the pressure drop not exceeding 5MPa.

Usage:

① Accompanies hydraulic cylinders or machinery, enabling operations such as lifting, bending, straightening, extrusion, cutting, riveting, disassembly, and installation.

② Used as a hydraulic power source in certain machinery and equipment.

③ Pressure testing station for various high-pressure hydraulic components, high-pressure vessels, and high-pressure hoses.
