P124 Series Hydraulic Gear Oil Pump P124-G16085DL54G

Information on P124 Series Hydraulic Pumps
The P124 series is a compact, high-reliability hydraulic pump product line
hydraulic component manufacturer). It is specifically engineered for light to medium-duty mobile and industrial hydraulic systems,
focusing on space efficiency and consistent performance. Below is its core information:
1. Core Product Nature & Positioning
The P124 series is mainly a gear-type hydraulic pump (available in single-pump configurations; some variants support multi-pump
combinations for integrated fluid power solutions). Its compact design makes it ideal for equipment with limited installation
space, while maintaining sufficient pressure output to meet medium-load hydraulic demands.
2. Key Technical Specifications
Specification CategoryTypical Parameters (Exact values vary by sub-model; for reference only)Working Pressure- Nominal pressure:
21 MPa
– Continuous operating pressure: Up to 25 MPa
– Peak pressure (intermittent): 28 MPaDisplacement Range10 ml/r ~ 80 ml/r (covers small to medium flow needs; specific
displacement is determined by sub-model suffixes)Speed Range- Maximum input speed: 3000 rpm
– Recommended operating speed: 1200 ~ 2600 rpm (balances efficiency and component lifespan)Construction & Materials- Pump body:
High-strength cast iron (GG20/GG25) for good rigidity and wear resistance
– Gears: Precision-machined carbon steel (15CrMn) with surface nitriding treatment (hardness HV 500-600) to reduce abrasion
– Seals: Nitrile rubber (NBR) as standard (compatible with mineral oil); fluororubber (FKM) optional for high-temperature
environmentsMounting & Connection- Mounting type: Compact SAE flange mounting (SAE A/B flange) or foot mounting (for
space-constrained setups)
– Port size: SAE straight thread ports (e.g., SAE 1/2″, SAE 3/4″) for easy connection to small-diameter hydraulic hosesEfficiency-
Volumetric efficiency: ≥ 90% (at rated pressure and speed)
– Mechanical efficiency: ≥ 88% (minimizes energy loss in light/medium-duty cycles)

3. Typical Applications
Given its compact size and medium-pressure performance, the P124 series is widely used in light to medium-duty equipment,
including:

* Small construction machinery: Mini excavators (1-3 tons), small loaders, and skid steer loaders
* Agricultural machinery: Compact tractors, small harvesters, and agricultural irrigation systems
* Material handling equipment: Small forklifts, electric pallet trucks, and conveyor systems
* Industrial auxiliary systems: Hydraulic power units for small presses, clamping devices, and machine tool auxiliaries

4. Key Notes for Selection & Maintenance
* Fluid Compatibility: Use ISO VG 32 or VG 46 mineral oil-based hydraulic fluid; ensure fluid cleanliness (particle count ≤ NAS
9) to avoid gear or seal damage.
* Temperature Adaptability: Recommended operating temperature: -5°C ~ 75°C; avoid long-term operation above 85°C (to prevent seal
aging).
* Model Differentiation: Sub-models are distinguished by suffixes (e.g., “G16IDY”, “G20NIG”) that indicate specific features like
flange size, port type, or pressure rating. Confirm the full model number with the manufacturer for precise parameters.
