Product Description
High-Strength Aluminum Die-Cast Body:
The SNP3 is built with high-tensile, specially treated aluminum bodies and covers, providing excellent structural integrity and heat dissipation. This lightweight yet rigid construction minimizes weight on the vehicle chassis while ensuring stable performance during high-pressure duty cycles in tough environments.
High-Performance Floating Bushing Design:
Utilizing advanced, pressure-balanced floating bushings, the SNP3 offers an increased bearing surface area that excels in high-pressure operations. This design is inherently more tolerant of fluid contamination and thermal shock, maintaining high volumetric efficiency while protecting the pump from premature wear during intensive use.
Sophisticated Axial Compensation Technology:
Equipped with precision-engineered pressure-balanced wear plates, the SNP3 features axial compensation that automatically optimizes internal clearances between the gear faces and the housing. This minimizes internal fluid bypass and friction, ensuring exceptional mechanical efficiency and consistent power delivery across a wide range of operating temperatures.
Superior High-Pressure and Speed Capability:
Despite its compact footprint, the SNP3 is engineered to handle continuous operating pressures of up to 3,625 psi (250 bar) and peak pressures up to 4,060 psi (280 bar). Its high-precision ground gears and hardened shafts allow it to handle input speeds up to 3,000 RPM, providing smooth and reliable flow for high-force actuators.
Modular Versatility and Installation Flexibility:
The SNP3 series offers a versatile range of displacements (from 22 to 88 cc/rev) and supports standard SAE "B" and "C" mounting options. With a wide variety of shaft, flange, and porting configurations, it provides unmatched installation flexibility for both single and multiple pump (tandem) combinations in complex mobile applications.
| Size | Displacement | Max. Continuous Pressure (bar) | Max. Speed (rpm) |

| 33 | 33.1 | 250 | 3000 |
| 44 | 44.1 | 250 | 3000 |
| 55 | 55.1 | 200 | 2500 |
| 75 | 75.2 | 170 | 2200 |
| 90 | 88.2 | 150 | 2000 |
Applications
Construction & Earthmoving Equipment: A primary choice for telehandlers, wheel loaders, and mini-excavators, where the SNP3 provides reliable power for steering systems, cooling fan drives, and auxiliary hydraulic functions.
Agricultural Machinery: Optimized for large tractors, combine harvesters, and sprayers, where its high volumetric efficiency and robust design ensure dependable performance for implement control and harvesting mechanisms in dusty field environments.
Material Handling Solutions: Widely used in high-capacity forklifts, reach stackers, and container handlers that require high-cycle, high-pressure stability to manage heavy lifting and precise load positioning operations.
Forestry & Timber Equipment: Ideal for log loaders, feller bunchers, and wood chippers, offering a durable power source that maintains high efficiency under the variable load shocks and extreme temperatures common in forestry work.
Specialized Utility Vehicles: Frequently employed in refuse collection trucks, road sweepers, and salt spreaders, where its modular design allows for multiple pump combinations to power complex compaction and cleaning circuits simultaneously.
SNP3 pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
High-Strength Aluminum Body: Specialized alloy construction provides excellent heat dissipation and structural integrity, maintaining tight internal clearances even under high-pressure duty cycles.
Floating Bushing Technology: It utilizes advanced, pressure-balanced floating bushings that offer a superior bearing surface, providing greater resistance to thermal shock and fluid contamination compared to basic designs.
Modular Versatility: The SNP3 offers an extensive range of mounting flanges (SAE B, C), shaft types, and porting options, providing significantly more installation flexibility for complex machine chassis.
Continuous Pressure: Up to 3,625 PSI (250 bar) for mid-range displacements.
Intermittent/Peak Pressure: Up to 4,060 PSI (280 bar).
Note: Larger displacements (e.g., 75 to 90 cc) have lower rated pressures to ensure long-term mechanical reliability.
Sauer-Danfoss: Legacy SNP3 / SNP3NN series (direct successor).
Casappa: Polaris PLP30 series.
Rexroth: AZPN series.
To ensure a successful swap, verify the Mounting Flange, Shaft Type (Splined, Keyed, or Tapered), and Displacement (cc/rev) to match your existing system.
Oil Type: High-quality mineral-based hydraulic fluids with anti-wear (AW) additives.
Viscosity: The optimal operating range is 20 to 100 cSt, though it can handle cold starts up to 1,600 cSt (7,500 SUS).
Filtration: Cleanliness is critical for aluminum pumps. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive wear of the internal surfaces.

SNP3 pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
