Key Technical Advantages

1. PGP315: Three-Piece Cast Iron Construction – Withstands Heavy-Duty Applications

The PGP315 series features three-piece cast iron construction with excellent structural strength and impact resistance. Compared to aluminum bodies, cast iron provides superior structural stability under extreme conditions of high temperature, high pressure, and high impact—particularly suited for construction, forestry, and oil & gas mobile equipment markets. Balanced thrust plates effectively reduce friction and internal leakage.

2. PGP511: 12-Tooth Gear Profile with Optimized Flow Metering – Ultra-Low Noise Operation

The PGP511 features a 12-tooth gear profile with optimized flow metering design. Compared to conventional gear pumps, this design effectively reduces pressure pulsation, delivering exceptionally smooth and quiet operation. The PGP511 series delivers superior performance, high efficiency, and low noise at high operating pressures.

3. High Volumetric Efficiency – Up to 98%

The PGP315 series achieves volumetric efficiency up to 98% through low-friction journal bearings and balanced thrust plate design. The PGP511 series also maintains high volumetric efficiency across all operating conditions through precision gear machining and optimized flow metering. High volumetric efficiency means lower power loss and reduced system heating.

4. Flexible Modular Design – Supports Single, Tandem, and Multiple Pumps

In addition to single pumps, the PGP series supports tandem and multiple pump configurations. The PGP315 series supports cross-frame multi-pump combinations, while the PGP511 series offers extensive combination options across four frame sizes (PGP502, PGP505, PGP511, PGP517).

5. Comprehensive Valve Integration Options

The PGP series supports integration of multiple hydraulic valve functions including relief valves, load-sense flow controls, priority valves, solenoid unloader valves, and accumulator charge valves. This high level of integration reduces external piping and fitting requirements, minimizes leak points, and simplifies system layout.

6. Broad Media Compatibility with Installation Flexibility

The PGP series supports standard hydraulic fluids, phosphate-ester, water-glycol, and other media. Mounting options comply with SAE, ISO, and DIN international standards, supporting SAE, ISO, NPT, and BSPP port connections for easy adaptation to various industrial equipment.

Expert Maintenance Tips

Model Code Verification (verify each element):

PGP series model codes contain critical information. Before selection and installation, confirm the following:

• PGP315 / PGP511: Product series and frame size.

• Displacement code (e.g., A193, M0160, etc.) : Corresponds to different displacement specifications.

• Configuration code (e.g., PQAB07, CS2D3NE5E3B1B1, etc.) : Shaft type, port specification, seal material, rotation direction.

• Suffix code: Additional configuration information.

Verify Rotation Direction:

Confirm that the drive shaft rotation matches the direction code in the model. PGP series offers clockwise, counter-clockwise, and bi-rotational options. Incorrect rotation will prevent pressure build-up and may damage internal gears and bearings.

Mounting Flange and Drive Shaft Matching:

PGP series offers a wide range of SAE, ISO, and DIN standard mounting flanges and shaft options. Verify that the equipment-side flange type and shaft specification match the pump configuration before installation.

Suction Line and Inlet Pressure Requirements:

PGP series requires an inlet absolute pressure range of 0.8 – 3 bar. Ensure the suction line is properly sealed with no air leaks and the suction filter is not clogged. Recommended suction vacuum does not exceed 0.3 bar (absolute pressure).

First-Start Priming Procedure:

After new pump installation or system overhaul, ensure the pump cavity is filled with oil before first start. Jog the pump at low speed and low pressure until the pump body is fully filled with oil and air is purged, then gradually increase to rated speed and working pressure. Running the pump dry will cause irreversible damage to gears and bearings.

Oil Cleanliness and Regular Maintenance:

Replace hydraulic oil and return filters every 1,000 operating hours or per equipment manufacturer recommendations. The PGP315 series recommends a minimum kinematic viscosity of 50 SUS, and the PGP511 series recommends hydraulic oil with proper cleanliness. Using hydraulic oil with proper cleanliness will significantly extend pump service life. Regularly monitor pump body temperature—if it consistently exceeds +80°C, inspect the system cooling.
