Salami Gear Pump 2.5PB Series (2.5PB-25, 2.5PB-28, 2.5PB-32) Parameter & Model Description
1. Model Code Interpretation
-
2.5PB: Series identifier, indicating a high-reliability external gear fixed displacement pump of the 2.5PB series produced by Salami, designed for medium-pressure hydraulic system requirements, with a compact structure, easy installation and stable operation, widely used in various industrial hydraulic scenarios.
-
25/28/32: Nominal displacement of the gear pump, corresponding to three specifications respectively: 25 cc/rev (2.5PB-25), 28 cc/rev (2.5PB-28) and 32 cc/rev (2.5PB-32), which can meet different medium-flow hydraulic power demands.

3. Performance Characteristics
-
Adopts a compact and robust external gear structure, with strong pollution resistance and low requirements on hydraulic oil cleanliness, which can adapt to harsh industrial working environments and reduce daily maintenance costs;
-
Features high efficiency (efficiency range 70% – 85%), stable output flow, and strong overload capacity, the three displacement specifications can be flexibly selected according to actual flow demands, 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 the interchangeability is strong, reducing replacement and maintenance costs;
-
The key components (gears, shaft, oil seal) are made of high-wear-resistant and corrosion-resistant materials, ensuring good sealing performance and long service life, effectively reducing the risk of hydraulic oil leakage and equipment failure.
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 of the three models, refer to Salami official technical manual (Document No. 2.5PB-Series-001).
