Product catalog summary
Overview: This document provides technical specifications and details for high-capacity gear pumps, specifically the SPA and SPG series, which are designed for working pressures up to 300 bar and displacements ranging from 0.9 to 61.1 cm³ per revolution.
Specifications:
  • Design: External gear pumps with flange mounting and threaded connections. Available in both anti-clockwise and clockwise rotations.
  • Materials: Housing made of aluminum or cast iron, with Teflon plain bearings.
  • Operating Conditions: Fluid temperature ranges from -15°C to +80°C, with a viscosity range of 10 cSt to 300 cSt. Recommended oil viscosity at 50°C is between 21 cSt and 46 cSt.
  • Filtration: Return line filtration with 10-25 µm mesh size is recommended, especially for higher operating pressures.
Drive and Mounting:
  • Drive Shaft: Standard cone with 1:8 ratio, allowing for axial movement to prevent axial forces on the pump shaft.
  • Mounting Position: Flexible, with no specific orientation required.
Performance Characteristics:
  • Pressure Ratings: Maximum continuous pressure, working pressure, and peak pressure are defined, with specific durations for each.
  • Speed and Displacement: Maximum speeds and displacements are provided for various pump types, with detailed tables for reference.
Ordering Information: The document includes a typology for ordering pumps, specifying direction of rotation, nominal size, drive shaft type, and construction type (SPA or SPG).
Dimensions and Capacity Data: Detailed tables provide dimensions, weight, and performance data for different pump models, including multiple pump combinations and their respective tightening torques.
Contact Information: HYDROPA GmbH & Cie. KG, located in Witten, Germany, with contact details for further inquiries.
