Features:

Small in size, light in weight, easy to use, and high working pressure.

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

③ Two-stage pump station: During low-pressure no-load filling, both high and low-pressure pumps supply oil simultaneously, achieving a higher output flow rate. During high-pressure operation, the low-pressure pump returns oil without load automatically through a de-load overflow valve, reducing power consumption.

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

Usage:

① Compatible with hydraulic cylinders or machinery, capable of lifting, bending, straightening, extruding, cutting, riveting, disassembly, and assembly operations.

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

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

A brief description of the structural principle

The D series electric pump station consists of an electric motor, R series radial plunger pumps (high-pressure pumps), low-pressure gear pumps, control valves, oil tanks, gauges, etc.
