As the core product of YUKEN industrial hydraulics, YUKEN A100 series variable piston pumps are widely used in industrial scenarios such as machinery manufacturing, engineering construction, and shipbuilding due to their high performance, stability and flexibility.The following analysis is carried out from the three aspects of technical characteristics, application advantages and selection points：
1. Technical characteristics: the dual guarantee of high efficiency and stability
Variable control technology
The A100 series adopts advanced variable plunger design, which realizes stepless flow adjustment by adjusting the angle of the swash plate.For example, the A100-FR01KS-10 model is equipped with a pressure compensator, which can automatically adjust the output flow according to the system load, maintain stable efficiency under high pressure conditions, and reduce energy loss.
Adaptability of pressure and speed
Rated pressure: 25MPa (some models such as A100-FR04HS-10 can reach 700bar) to meet the needs of medium and high pressure systems.
Speed range: Standard models support 1000-3000rpm, and models such as A100-LR01BS-10 can reach the maximum flow rate at 1800rpm to avoid wear caused by long-term overspeed operation.
Wear-resistant and sealing design
The pump body is made of cast iron or high-strength alloy steel, and the key components (such as plunger and swash plate) are specially heat treated to increase the wear resistance by more than 30%.The seal is made of fluorine rubber or polytetrafluoroethylene, which is suitable for a wide temperature range of -20℃ to 80℃, and the leakage rate is less than 0.1ml/min.

2. Application advantages: multi-scene adaptation and cost reduction and efficiency enhancement
Industrial automation production line
The A100 series provides precise pressure control for injection molding machines and die-casting machines (such as A100-FR01H-S-60 model pressure fluctuation ≤±0.5MPa) to ensure product molding consistency and increase the yield by 15%.
Hydraulic system of construction machinery
In excavators and loaders, the A100-LR01CS-10 model adopts the pressure compensation function to speed up the response speed of the hydraulic cylinder by 20%, while reducing the heat generation of the system and extending the hydraulic oil replacement cycle to 2000 hours.
Ships and marine platforms
The A100-FR04B-K-A-3266 model adopts double-bolt flange installation, with an impact resistance of up to 5g, adapts to the bumpy environment of the ship, and provides stable power output for the steering gear and anchor gear.
Energy saving and environmental protection benefits
Pressure compensation control technology reduces system energy consumption by 12%-18%.For example, in a continuous casting machine in a steel plant, after replacing the fixed displacement pump with the A100 series pump, the annual power saving can reach 50,000 kWh and reduce CO排放 emissions by about 40 tons.
