Information on P7600 Series Hydraulic Pumps
The P7600 series is a high-performance hydraulic pump product line typically associated with Permco (a leading global manufacturer
of hydraulic components), designed for heavy-duty industrial and mobile hydraulic applications. Below is a detailed breakdown of
its core information:
1. Core Product Positioning
The P7600 series is primarily a gear-type hydraulic pump (single or dual pump configurations available), engineered to deliver
reliable performance in high-pressure, continuous-operation scenarios. It is widely used in heavy mobile machinery and industrial
equipment that demands stable fluid power output.
2. Key Technical Specifications
Specification CategoryTypical Parameters (for reference; exact values vary by sub-model)Working Pressure- Nominal pressure: 28 MPa
– Continuous operating pressure: Up to 31.5 MPa
– Peak pressure (intermittent): 35 MPaDisplacement Range45 ml/r ~ 220 ml/r (covers small to large flow requirements; specific
displacement depends on sub-model suffix)Speed Range- Maximum input speed: 2800 rpm
– Recommended operating speed: 1500 ~ 2500 rpm (optimizes efficiency and lifespan)Construction & Materials- Pump body:
High-strength cast iron (GG25/GG30) for wear resistance and pressure tolerance
– Gears: Precision-ground alloy steel (20CrMnTi) with surface hardening (HRC 58-62) to reduce friction
– Sealing elements: Nitrile rubber (NBR) or fluororubber (FKM) for compatibility with mineral oil-based hydraulic fluidsMounting &
Connection- Mounting type: SAE flange mounting (SAE B or C flange) for easy integration with standard machinery
– Port size: SAE straight thread ports (e.g., SAE 3/4″, SAE 1″) for flexible hydraulic line connectionEfficiency- Volumetric
efficiency: ≥ 93% (at rated pressure and speed)
– Mechanical efficiency: ≥ 90% (minimizes energy loss)

3. Common Sub-Models & Application Scenarios
The P7600 series includes multiple sub-models (differentiated by suffixes like “AHNJ”, “ADNO”) tailored to specific equipment
needs:

excavators)P7600A383ADNO17-25Mining equipment (e.g., small mining loaders, ore conveyors)P7600F50ZF486-30Agricultural machinery
(e.g., large tractors, combine harvesters)P7600D231IXZA10-18Industrial hydraulic systems (e.g., hydraulic presses, heavy-duty
conveyors)

4. Operational & Maintenance Notes
* Fluid Requirement: Use ISO VG 32 or VG 46 mineral oil-based hydraulic fluid; avoid contamination (particle count ≤ NAS 8).
* Temperature Range: Recommended operating temperature: -10°C ~ 80°C; avoid prolonged exposure to temperatures above 90°C (to
prevent seal degradation).
* Maintenance Interval: Replace hydraulic oil and oil filter every 2000 operating hours; inspect gear wear and seal integrity
annually.

Note: Exact parameters (e.g., displacement, port size) may vary by specific sub-model. For precise data, refer to Permco’s
official technical documentation or contact the manufacturer with the full model number.
