Product catalog summary
Overview: The document outlines the technical specifications and installation guidelines for the HQI2 and HQI3 series internal gear pumps by HOERBIGER, designed for industrial applications such as sheet metal working machines, presses, and conveying technology.
Specifications: The HQI2 series features internal gear pumps with a displacement volume of 5 - 25 cm³/rev, known for low noise due to minimal flow and pressure pulsation. They are robust and reliable, suitable for demanding environments. The HQI3 series offers similar features with a constant displacement volume and is designed for low noise operation.
Design and Features: Both series include radial and axial compensation to minimize leakage, with radial compensation achieved through a split filler and spring-loaded sealing roller, and axial compensation via axial discs. The pumps are designed for flange mounting with SAE-A-2 port size.
Performance Parameters: HQI2 pumps operate at continuous pressures up to 330 bar (NG 5 - NG 16) and a maximum of 350 bar, with drive speeds up to 4200 min-1. HQI3 pumps operate at continuous pressures of 330 bar (NG20-NG32) and 250 bar (NG40-NG50), with maximum pressures of 350 bar (NG20-NG32). The ambient temperature range is -40°C to +80°C for HQI2 and -20°C to +80°C for HQI3.
Installation Guidelines: Proper alignment of the motor and pump is crucial, avoiding radial or axial forces on the pump drive shaft. Use couplings to compensate for shaft misalignment, and ensure piping is clean and pressure-tight. The return outflow must be below the oil surface.
Operational Recommendations: Ensure the system is cleanly installed and filled with hydraulic fluid through appropriate filters. The pump should not be run without oil, and operations should adhere to specified parameters. Only authorized personnel should perform assembly, maintenance, and repairs.
Safety and Compliance: The pump must be operated within permissible data, and modifications affecting safety and function are prohibited. General safety regulations and accident prevention rules must be followed.
Technical Characteristics: The pumps are phosphated for rust protection and use mineral oil according to DIN51524, with a viscosity range of 10 to 300 mm²/s. The contamination level should not exceed class 8 according to NAS1638, with a filter recommendation of retention rate β10>100.
Applications: These pumps are suitable for use in sheet metal working machines, presses, conveying technology, and special purpose machines.
