3. Performance Characteristics
-
Adopts a simple and robust external gear structure, with strong pollution resistance and low requirements on hydraulic oil cleanliness, which can adapt to harsh working environments and reduce maintenance costs;
-
Features high efficiency (efficiency range 70% – 85%), stable output flow, and strong overload capacity, suitable for long-term continuous operation in medium-pressure working conditions;
-
The installation and connection dimensions comply with ISO international standards, facilitating replacement with domestic and foreign similar gear pump products and reducing replacement costs;
-
The key components (gears, shaft, oil seal) are made of high-wear-resistant materials, and the FG-type shaft seal is specially configured to ensure good sealing performance and long service life, reducing the risk of hydraulic oil leakage.
4. Application Scope
5. Notes
-
The pump should be used within the specified temperature and viscosity range, and the hydraulic oil should be regularly filtered to avoid performance degradation or component wear caused by excessive temperature, inappropriate oil viscosity or oil pollution.
-
When installing, use the specified number and strength class of bolts, and tighten them according to the recommended torque to prevent bolt damage, pump loosening and hydraulic oil leakage.
-
For detailed dimensions, oil port specifications, maintenance methods and spare parts information, refer to Marzocchi official technical manual (Document No. GHP2A-Series-001).
