Drive mode: support electric or hydraulic drive, voltage selectable 110V/220V AC (50/60Hz) or 24V DC.
Noise level: lower than 60dB (A), low noise operation in full pressure zone.
Structure and material characteristics
Pump type: V-type variable piston pump, with swash plate angle change design for flow regulation.
Material: cast iron shell, horizontal installation structure, axial flow design.
Impeller type: open impeller, single-stage single-suction design.

Product advantages and application scenarios
Core advantages
High-efficiency and energy conservation: small power loss, slow rise of oil temperature, suitable for small oil tank, reducing system cost.
Low-noise operation: the noise within the full pressure range shall be controlled below 60dB (A), suitable for the environment sensitive to noise.
System integration: support combination of multiple control modes to realize energy saving and miniaturization design.
Reliability: high sensitivity, good stability, long service life, improving the operation reliability of the host.
Typical application fields
Industrial machinery: tool machines, machine tools, forging and pressing equipment.
Forming equipment: plastic forming machine and injection molding machine.
Other scenes: hydraulic system integration, automatic production line and other equipment requiring high pressure stable output.

Precautions and maintenance suggestions
Selection of working medium oil
Viscosity requirements: ISOVG32-68 common working medium oil (R&O) shall be used under the working conditions below 7MPa; Wear-resistant working medium oil shall be used above 7MPa, with viscosity range of 15~400mm ²/s (cSt).
Pollution control: the oil pollution degree shall be kept within NAS9 to avoid pump failure or shortened service life caused by impurities.
Installation and Operating Specification
Shaft center alignment: the eccentricity of transmission shaft and pump shaft shall be ≤ 0.05mm (TIR) to avoid the damage of bearing and oil seal caused by radial force.
Oil temperature control: the operating oil temperature shall be maintained at 0 ～ 60 ℃, and the service life of the seal may be affected if the temperature exceeds the range.
Anti-funterfeiting prompt: there are many fake goods in the market, so it is suggested to ask for physical photos and purchase through formal channels.
