YUKEN A37-F-R-01-B-K-32 Variable Displacement Piston Pumps
YUKEN A37-F-R-01-B-K-32 Series Variable Displacement Piston Pump – Models & Parameters
1. Model Description (YUKEN A37-F-R-01-B-K-32)
The model code of YUKEN A37-F-R-01-B-K-32 series variable displacement piston pump follows YUKEN’s standard coding rules, and each segment represents specific technical characteristics, which are closely related to the pump’s structure, installation and working performance, as detailed below:
- A37: Basic model, indicating the nominal displacement series. The A37 series is a medium-displacement variable piston pump, specially designed for medium-pressure hydraulic working conditions, with reliable performance and wide adaptability, and its nominal displacement matches the 37 series specification.
- F: Mounting type, specifically flange mounting. This is a common installation method in industrial hydraulic systems, which can ensure stable connection between the pump and the power unit, reduce vibration during operation, and ensure reliable and long-term operation.
- R: Rotation direction, representing clockwise rotation (viewed from the shaft end). This is the standard rotation direction for most matching hydraulic equipment, which is convenient for matching with motors and other power components.
- 01: Control type, indicating manual proportional control. It can manually adjust the displacement of the pump according to the actual working demand of the system, with simple operation and high control accuracy, suitable for occasions with stable working conditions.
- B: Valve configuration, indicating the built-in relief valve. The built-in relief valve can effectively protect the pump body and the whole hydraulic system from overpressure damage, improving the safety and stability of the system operation.
- K: Additional configuration, including special seal type and material adaptation design. It has good sealing performance and can adapt to different working environments, including some medium-temperature and medium-pressure harsh working conditions, and can effectively extend the service life of the pump.
- 32: Installation flange standard, complying with the relevant industrial standard specifications, which is convenient for the interchangeability of the pump in different equipment, and facilitates later maintenance and replacement.
