GD5-Series

Product catalog summary

General Introduction
Eaton's GD5 Series External Gear Pumps are engineered for high-pressure applications, offering quiet operation and durability. They feature a pressure-balanced design with a robust extruded aluminum body and options for aluminum or cast iron end covers. The pumps are versatile, with various shafts, flanges, and ports that meet international standards. Displacements range from 5.1 cm³/rev to 24.0 cm³/rev, with a maximum pressure capacity of 210 bar.

Hydraulic System Design Calculations
The document includes formulas for calculating output flow, input power, shaft torque, and speed. It provides conversion factors for different units and efficiency calculations for both volumetric and mechanical efficiency.

Parts Nomenclature
Details are provided for single and double pump configurations, including sectional sealing for double pumps. Key components include the center section, flange, end cover, and input shaft.

Model Codes
Model codes for single and double pumps specify features such as seal packs, displacement, mounting flange, drive shaft, port options, rotation, and design number. Customization options are available through consultation with Eaton representatives.

Specifications
The pumps are field reversible with a maximum axial load of 1000 N. Recommended fluid viscosity is between 16 to 40 cSt, with an operating temperature range of -30°C to 100°C. The inlet pressure range is -0.2 bar to 2.0 bar.

Performance Curves
Performance data is provided for various displacements, showing volumetric efficiency and torque across different speeds and pressures. Efficiency ranges from 92% to 100% depending on conditions, using mineral-based oil with a viscosity of 28 cSt at 45°C - 50°C.

Component Dimensions
Detailed dimensions for mounting flange options (SAE, German, European), input shaft options (straight keyed, taper, teeth shafts), and port options (SAE, European, German, BSPP, Metric) are provided, with measurements in mm and inches.

Installation & Maintenance
Guidelines include mounting orientations, rotation direction, drive coupling recommendations, fluid specifications, reservoir capacity, line diameters, filtration standards, and startup procedures. Emphasis is placed on maintaining cleanliness and proper alignment to prevent premature failures.

Changing Rotation
A step-by-step procedure is outlined for changing the pump's rotation, which should be performed by trained personnel. This involves repositioning gears and reassembling components with specified torque values.

Spares
Information on available seal kits for different pump configurations (single, double, sectional sealing) is provided, including part numbers for Nitrile and Viton materials.

Mounting Pump can be mounted with Drive Shaft in horizontal, vertical or at any angle in between. All Flanges have pilot (Spigot) for proper alignment of Pump with respect to drive system. Rotation Shaft rotation is denoted in the unit coding. Arrow indicating direction of rotation is stamped on Pump's Centre Body. Direction of rotation is as viewed from Pump's Drive Shaft end. Drives Coupling used to drive the pump should not transfer any radial or axial load on Pump's Drive Shaft. A flexible coupling is recommended to accommodate slight misalignment & to dampen the vibration. Fluids Pressure...
