Overview: The document provides technical specifications and guidelines for high-capacity gear pumps, specifically multiple pumps assembled from standard single pumps. These pumps are designed for working pressures up to 270 bar and have a displacement range from 0.9 to 61.1 cm³ per revolution.
Specifications:- Design: External gear pump with flange mounting and threaded connections.
- Materials: Aluminium housing 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.
- Pressure Ratings: Maximum continuous pressure is specified, with peak pressures allowed for short durations.
Procedures:- Mounting: The pump can be mounted in any position, with specific guidelines for coupling to prevent axial and radial forces on the pump shaft.
- Filtration: Return line filtration with 10-25 µm mesh is recommended, with finer filtration for higher pressures.
Performance Data:- Detailed tables provide displacement, maximum speed, and pressure ratings for various pump models (1 SPA, 2 SPA, 3 SPA).
- Torque specifications for screw tightening are provided for different pump combinations.
Ordering Information: A typology key is provided to specify pump configurations, including direction of rotation, drive shaft type, and construction type.
Additional Information: Contact details for Hydropa GmbH & Cie. KG are provided, along with a note on the company's commitment to innovation and quality.
