Understanding the SGP1 Model Number System
To navigate the SGP1 series, it's essential to understand the model number system. The model number consists of several components that specify the pump's features:
- SGP1: Denotes the series and indicates a cast-iron body gear pump.
- Numerical Value (e.g., 25, 27, 30): Refers to the pump’s approximate displacement in cubic centimeters per revolution (cm³/rev).
- Letter Codes:
- "F" or "D": Indicates port configuration (F for rear cover side ports, D for rear ports).
- "H": Denotes horizontal two-bolt mounting.
- Shaft End Codes (e.g., 1, 2, 5): Specify the shaft end type (e.g., SAE Spline with 13 teeth).
- Rotation ("L" for counterclockwise, "R" for clockwise).
- "A": Signifies a variation in the mounting spigot diameter or design iteration.
- Suffixes like "AL" or "AR": Represent specific modifications or regional designations.
For example, SGP1-25F1H1-L can be broken down as follows:
- SGP1: Cast-iron gear pump series.
- 25: Approximate displacement of 25 cm³/rev.
- F: Rear cover side ports.
- 1H: SAE Spline with 13 teeth shaft end and horizontal mounting.
- L: Counterclockwise rotation.
Core Strengths: Features and Benefits of the SGP1 Series
The SGP1 series is widely praised for several key features that translate to tangible benefits for users:
- High Efficiency: The precise meshing of internal gears minimizes internal leakage, ensuring optimal energy conversion and low power consumption. The axial clearance compensation and radial hydraulic balance mechanisms further enhance efficiency across various operating conditions.
- Low Noise and Vibration: The compact design and smooth operation minimize noise and vibration, contributing to a more stable working environment and potentially extending the lifespan of connected components.
- Durability and Reliability: Built from high-quality materials, the SGP1 pumps are engineered to withstand demanding conditions, ensuring a long service life. The pumps pass rigorous tests, including one million impact fatigue tests under high pressure, highlighting their resilience.
- Versatility: The SGP1 series supports a wide range of applications, including material handling, construction machinery, agricultural machinery, and more. Its small size and high power density make it suitable for space-constrained environments without sacrificing performance.
Applications of the SGP1 Series
The SGP1 series is used in various industries, including:
- Material Handling: Forklifts, conveyors, hoisting machinery.
- Construction Machinery: Excavators, pavers, bulldozers, concrete pump trucks.
- Agricultural Machinery: Tractors and other farming equipment.
- Industrial Vehicles: Road machinery, environmental sanitation equipment.
- Other: Marine machinery, cranes, and potentially aerospace systems.
SGP1 Model Variations
The SGP1 series includes models differentiated by displacement, port configuration, shaft end type, and rotation direction. These models can be categorized into three main displacement groups:
- SGP1-25: Approximate displacement of 25 cm³/rev, suitable for medium-duty applications.
- SGP1-27: Approximate displacement of 27.8 cm³/rev, providing slightly higher flow rates.
- SGP1-30: Approximate displacement of 29.9 cm³/rev, offering the highest flow rates in the series.
Within each displacement category, you will find variations in port configurations, shaft end types, and rotation directions. Models with the "A" prefix denote specific design variations, while suffixes such as "AL" or "AR" indicate additional modifications.
Conclusion
The Shimadzu SGP1 series gear pumps stand out due to their high efficiency, low noise, durability, and versatility. With a well-structured model number system, users can easily identify the ideal pump for their hydraulic systems. Whether for material handling, construction machinery, or agricultural applications, the SGP1 series offers reliable and efficient solutions for a wide range of industries.
