Product Description
Rugged Three-Piece Cast Iron Construction:
The P330 is built with high-tensile, heavy-duty cast iron bodies and covers, providing superior structural rigidity compared to aluminum alternatives. This robust construction minimizes internal deflection and mechanical fatigue under high-pressure duty cycles, ensuring stable performance and extended service life in grueling work environments.
High-Performance Bushing Design:
Utilizing advanced, pressure-balanced bushings instead of roller bearings, the P330 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.
Advanced Pressure-Balanced Wear Plates:
Equipped with sophisticated axial compensation technology, the P330 features pressure-balanced wear plates that automatically optimize 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 all operating temperatures.
Superior High-Pressure Capability for High Flow:
The P330 is engineered to handle continuous operating pressures of up to 3,500 psi (241 bar) while delivering higher flow rates than smaller series. Its high-strength alloy steel gears and precision-machined components allow it to power heavy-force actuators and large-scale hydraulic circuits with smooth, reliable flow.
Modular Versatility and Installation Flexibility:
The P330 series offers a versatile range of displacements (from 16.1 to 64.6 cc/rev) and supports standard SAE "B" and "C" mounting options. Available in single, tandem, or multiple unit configurations, it provides unmatched installation flexibility for complex hydraulic systems and specialized heavy-duty mobile equipment.

Applications
Heavy Construction Machinery: A primary choice for wheel loaders, motor graders, and medium excavators, where the robust bushing design handles high-pressure spikes and ensures reliable power for heavy lifting and steering.
Mining & Quarrying Equipment: Optimized for underground loaders and rock drills, where the cast iron construction and bushing design ensure long-term durability against extreme vibrations and high-cycle duty in harsh environments.
High-Capacity Refuse Vehicles: Widely used in large rear-loaders and industrial compactors that require consistent high-pressure performance to manage heavy waste compaction and rapid unloading operations.
Heavy Material Handling: Ideal for container handlers, reach stackers, and large rough-terrain forklifts, offering a durable and efficient power source that maintains high stability under maximum load conditions.
Forestry & Logging Equipment: Frequently employed in large feller bunchers and log processors, where the P330 handles variable load shocks and fluid contamination common in demanding outdoor wood-processing environments.
P330 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.
The P330 is a heavy-duty, fixed-displacement bushing-style gear pump and a high-flow component of Parker's cast iron series. Featuring a rugged three-piece cast iron construction, it is specifically engineered for systems that require high structural integrity and reliable power output at higher flow rates than the P315 series.
Continuous Pressure: Up to 3,500 PSI (241 bar).
Intermittent/Peak Pressure: Up to 3,750 PSI (258 bar).
This robust pressure rating makes the P330 ideal for driving large-scale hydraulic cylinders and heavy-duty motors.
Metaris: MH330 Series.
Permco: P2500 Series.
Commercial Intertech: Older 330 series units.
To ensure a successful swap, verify the Mounting Flange (SAE B or C), Shaft Type (13-tooth or 14-tooth spline), and Displacement (Gear Width).
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100 to 150 SUS (20 to 30 cSt).
Filtration: Cleanliness is vital. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent bushing damage.
Minimum Speed: 600 RPM.
Maximum Speed: Up to 3,000 RPM (for gear widths up to 1.50").

P330 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.
