Product Description

PGP365 Gear Pump  Overview

The Parker PGP365 is an ultra-heavy-duty, fixed-displacement bushing-style gear pump engineered for high-flow hydraulic systems operating under the most grueling conditions. Representing the largest and most powerful frame size in the PGP300 family, it features a massive  three-piece cast iron construction. The PGP365 is specifically designed for high-torque applications such as large dump trailers, heavy-duty log loaders, and mining equipment, where maximum power density and uncompromising structural rigidity are required to handle massive fluid volumes at high pressure.

Features and Benefits

  • Maximum Power Density and High Flow:
    The PGP365 is engineered with larger gear widths to provide significantly higher flow rates (up to 9.0 in⊃3;/rev) compared to the PGP350. This makes it the ideal solution for large-scale hydraulic systems that demand high-speed actuator movements without sacrificing pressure capability.

  • Ultra-Robust Three-Piece Cast Iron Housing:
    Constructed from high-tensile strength cast iron, the PGP365 offers unmatched resistance to internal pressure spikes and mechanical stress. This rigid housing prevents body deflection, ensuring consistent volumetric efficiency and a long service life even when operating at the upper limits of its performance envelope.

  • High-Torque Drive Capability:
    To accommodate its high flow output, the PGP365 is typically equipped with SAE "C" mounting and high-capacity shaft options (such as 14-tooth splines). These components are precision-hardened to transmit the extreme torque required for heavy-duty PTO and engine-drive applications.

  • Advanced Bushing-Style Bearings:
    The pump features heavy-duty, pressure-balanced bushings that provide an increased bearing surface area. This design enhances the pump's ability to handle thermal expansion and ensures smooth operation even when using fluids with variable viscosity or under high-load cycles.

  • Superior Durability in Harsh Environments:
    The PGP365 is built to survive in "dirty" environments. Its specialized sealing system and rugged internal components are highly resistant to fluid contamination and abrasive wear, making it a reliable workhorse for forestry, waste management, and heavy construction industries.

Applications

The PGP365 series is engineered for ultra-high-power requirements in heavy-duty machinery, providing maximum hydraulic flow for large-scale operations:
  • Large Dump Trailers & Walking Floors: The standard choice for long-bed dump trailers and "walking floor" unloading systems that require massive fluid volume to move heavy loads quickly.

  • Forestry & Log Loaders: Powers high-torque log grapples and loader arms in the forestry industry, where high-cycle speed and extreme mechanical durability are required.

  • Mining & Earthmoving Equipment: Used in large articulated haulers and heavy excavators for auxiliary systems, providing high-pressure power for steering and specialized tool attachments.

  • Heavy-Duty Recovery Vehicles: Ideal for large tow trucks and rotators that use high-capacity hydraulic winches and booms to recover heavy commercial vehicles.

  • Mobile Shredders & Chippers: Drives high-power motors in industrial wood chippers and waste shredders, where constant high-torque output and resistance to vibration are essential.

PGP365 Gear Pump  FAQ

1. What are PGP365 series gear pumps

The PGP365 is the largest and most powerful fixed-displacement bushing-style gear pump in the PGP300 family. Built with an oversized three-piece cast iron frame, it is designed for heavy-duty applications that require significantly higher flow rates than the PGP350, while maintaining the same rugged reliability and high-pressure capability required for PTO and engine-drive systems.

2. What makes the PGP365 different from PGP350 pumps

While both share the same heavy-duty cast iron DNA, the PGP365 is the "high-flow" version:
  • Greater Displacement: The PGP365 offers gear widths up to 3.0 inches, providing flows up to 8.1 in⊃3;/rev, compared to the 5.1 in⊃3;/rev limit of the PGP350.

  • Stronger Drive Input: Due to its higher power output, the PGP365 typically utilizes larger SAE "C" mounting and shafts to handle the increased torque requirements.

  • Larger Porting: It features oversized inlet and outlet ports to accommodate the massive fluid volume without causing excessive heat or cavitation.

3. What is the working pressure range of PGP365 pumps

The PGP365 is built for high-force applications. Its pressure ratings are dependent on the gear width:
  • Narrower Gears (up to 2.0"): Continuous pressure up to 3,500 PSI (241 bar).

  • Wider Gears (up to 3.0"): Continuous pressure ranges from 2,500 to 3,000 PSI to balance the high flow with structural load limits.
    This allows the PGP365 to drive large-scale multi-stage cylinders and high-torque hydraulic motors with ease.

4. Can PGP365 pumps replace other brands

Yes, the PGP365 is a global standard for high-flow cast iron pumps. It is a direct functional replacement or upgrade for:
  • Commercial Intertec: P365 Series.

  • Permco: P7600 Series.

  • Metaris: MH365 Series.
    Before replacing, ensure your PTO or drive engine can provide the higher torque required by the PGP365's larger displacement.

5. What are the key maintenance requirements for PGP365 gear pumps

Because the PGP365 moves large volumes of oil, heat management and oil cleanliness are critical:
  • Filtration: A minimum of ISO 4406 19/17/14 filtration is mandatory to protect the high-capacity bushings from abrasive wear.

  • Inlet Conditions: Ensure the suction line is sufficiently large to prevent cavitation, as the PGP365 demands high volumes of fluid during high-speed operation.

  • Seal Care: Always use high-quality viton or nitrile seals if operating in extreme temperature environments (forestry or mining).

6. What is the typical speed range of PGP365 pumps

The PGP365 is optimized for heavy-duty drive speeds, typically operating between 600 RPM and 2,400 RPM, making it perfectly suited for direct-mount PTO applications on heavy commercial chassis.

FAQ

1.How does the variable displacement work?

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.
