PGP517B0160CD1H3VE6E5S Parker Gear Pump 250bar 16cc

Product Overview

The PGP517B0160CD1H3VE6E5S is an aluminum tandem external gear pump from the Parker Hannifin PGP517 series. This model features two pump sections connected in series, each with a displacement of 16.0 cm³/rev, for a total displacement of 32.0 cm³/rev. It corresponds to Parker part number 3339121186.

Engineered with Parker’s signature three-piece aluminum construction, the pump features pressure-balanced thrust blocks and journal bushings for exceptional durability, high efficiency, and long service life. As a tandem configuration, this pump delivers two independent oil flows from a single drive input, significantly simplifying hydraulic system architecture. This model falls in the mid-displacement range of the PGP517 series (series displacement range 14–70 cm³/rev).

Every unit is manufactured to original equipment specifications, ensuring 100% drop-in interchangeability with genuine Parker PGP517 series pumps without any system modifications. Each pump undergoes rigorous 100% simulated duty-cycle testing on dedicated test benches to validate pressure-flow-efficiency performance curves.

Key Technical Advantages

1. Lightweight Aluminum Alloy Construction

Featuring Parker’s signature aluminum alloy housing, the pump achieves 30%–50% weight reduction compared to conventional cast iron equivalents. Weighing approximately 20 kg in tandem configuration, it delivers excellent pressure containment at 250 bar continuous rating while significantly reducing overall system weight—ideal for weight-sensitive mobile equipment and aerial lift platforms.

2. Pressure-Balanced Thrust Blocks & Journal Bushings – High Efficiency & Long Life

Integrated pressure-balanced thrust blocks automatically compensate for gear end clearance under high pressure, significantly reducing internal leakage. Paired with journal bushings, friction losses are minimized while extending service life. Volumetric efficiency reaches ≥92%, with overall efficiency ≥85%.

3. Three-Piece Modular Construction & Tandem Configuration Flexibility

The three-piece modular construction supports single, tandem, and multiple pump configurations. This model features a tandem configuration (16+16 cc) with independent displacement per section, enabling simultaneous or separate oil supply for complex hydraulic systems.

4. 13-Tooth Optimized Gear Profile & Low-Noise Operation

The 13-tooth high-wear alloy steel gear pair with optimized tooth profile delivers exceptionally smooth operation. Noise levels are as low as approximately 63 dBA @ 2,950 rpm—making it particularly suitable for cab-near installations and urban equipment operations.

5. Broad Speed & Temperature Operating Range

Supports a wide speed range of 500 to 3,400 rpm with operating temperature range from -20°C to +105°C (FKM seals). Maintains stable flow characteristics from cold start to high-speed continuous duty.

6. Thru-Drive Capability & Multi-Section Expandability

This model features thru-drive capability, allowing tandem connection of additional hydraulic pump sections on the same input shaft. Systems can be flexibly expanded to three or more sections to meet complex multi-circuit hydraulic demands.

7. 100% Simulated Duty-Cycle Testing

Every pump is 100% tested on dedicated hydraulic test benches under simulated real-world operating conditions—validating pressure-flow characteristics and efficiency curves at rated pressure (250 bar), peak pressure (310 bar), and full speed range—ensuring zero-defect, plug-and-play performance upon installation.

Expert Maintenance Tips

1. Fluid Cleanliness Control

Maintain system fluid cleanliness to ISO 4406 19/17/13 or better. Install a ≤10 μm absolute filtration filter upstream of each inlet port to prevent particle contamination from damaging precision gear pairs, journal bushings, and thrust plates.

2. Inlet Line Requirements

Keep suction lines short and straight with adequate diameter—not less than the port size. Inlet pressure must be maintained between 0.8–2.0 bar (absolute) , with absolute minimum of 0.5 bar. Recommended suction line flow velocity: ≤2.5 m/s. Both inlet ports of the tandem pump must be supplied with sufficient flow independently to prevent cavitation.

3. Coupling Alignment Precision

Flexible couplings are recommended for direct drive. Ensure pump shaft-to-drive shaft coaxiality deviation ≤0.05 mm and angular deviation ≤0.5° during installation. If the drive involves sprockets or V-belt pulleys, an independent outboard bearing MUST be installed to protect pump shaft bearings.

4. First-Start Priming Procedure

Before initial startup, bleed air through both outlet ports or drain ports separately. Perform 2–3 jog starts with outlets open (no load) until oil fills both pump sections without air bubbles, then connect load circuits for full operation.

5. Fluid Temperature Monitoring

Recommended operating temperature range: +15°C to +80°C (FKM seals up to +105°C). During cold starts (-20°C to -15°C), speed must not exceed 1,500 rpm. When viscosity exceeds recommended range during cold starts, ensure adequate suction conditions.

6. Rotation Direction Confirmation

This model is standard configured for clockwise (CW) rotation (viewed from drive shaft end). Always verify that the drive motor/engine rotation matches the pump before installation. Specify counterclockwise (CCW) configuration when ordering if required.
