HG internal gear pumps catalogue

Product catalog summary
Model Code for Single Pumps: The HG series includes single and double internal gear pumps. The model code for single pumps specifies the pump type, displacement, size, direction of rotation, seal type, shaft type, and mounting flange.
Suction and Displacement Procedure: The pinion shaft drives the internal gear, creating tooth clearances that prime the fluid, which is then transported from the suction area to the pressure area. Radial and axial compensation elements maintain high volumetric efficiency.
Structure and Components: These pumps are gap-compensated internal gear pumps with fixed displacement, featuring components like the mounting flange, housing, pinion shaft, internal gear, and compensation elements.
Technical Data: For frame size HG0, the speed range is 600 to 3000 rpm, with a displacement range from 8.2 to 20.0 cm³. Operating pressure ranges from 0.8 to 2 bar at input and up to 315 bar at output for HLP fluid. The pumps are designed for specific rotation directions and accommodate various hydraulic fluids.
General Specifications: The pumps feature an internal gear design with gap compensation, SAE 2 hole flange mounting, and are suitable for use with specified fluids, adhering to cleanliness class requirements.
Technical Specifications: Detailed specifications include displacement, flow rates, moment of inertia, operating pressures, and speed ranges, categorized by frame size and model.
Pressure and Flow Characteristics: The document outlines nominal and maximum pressures for different fluids and details flow rates for each model.
Sound Level and Power Diagrams: Diagrams illustrate the relationship between operational pressure and sound level, as well as driving power for different models.
Installation Dimensions: Installation dimensions for different pump series are provided, specifying port flange dimensions and shaft types.
Model Coding: A model code system identifies specific pump configurations based on displacement and other characteristics.
Key Data from Diagrams: Sound levels range from 45 dB(A) to 85 dB(A), and driving power varies across models, with higher power requirements at increased pressures.
Overview: The document provides technical specifications, installation guidelines, and project planning data for the HG22 Double Internal Gear Pump-S.
Specifications: It outlines dimensions and port sizes for different pump sizes, using SAE standards for port dimensions.
Intended Use: Designed for hydraulic systems in machine and plant construction, not suitable for explosive environments.
Technical Information: Compliance with technical data and operating conditions is crucial, as changes in conditions can affect performance.
Hydraulic Project Planning: Includes bleeding options, suction line design, pressure line considerations, and pressure limitation requirements.
Mechanical Project Planning: Covers installation and disassembly requirements, reservoir recommendations, and best practices for air tightness and fluid cleanliness.
Specifications and Installation Requirements: Emphasizes pre-tensioning pumps using air pressure and selecting appropriate reservoir fittings.
Installation Positions and Torque Calculations: Specifies permissible installation positions and provides torque calculation formulas.
Pump Combinations and Maintenance: Stresses compliance with operating data, checking maximum torque, and recommends a maintenance schedule.
Commissioning and Operation: Ensures correct installation and filling with hydraulic fluid, monitoring noise and operational changes.
Re-commissioning and Safety Notes: Involves checking for leaks, re-bleeding, and adhering to safety regulations, with repairs conducted by authorized personnel only.
