Key Technical Advantages

1. Helical Gear Design for Ultra-Low Noise Operation
The helical gear technology delivers an average noise reduction of 15dB(A) compared to conventional external gear pumps. This makes the G55C series ideal for noise-sensitive industrial environments such as injection molding workshops and precision machining centers, while eliminating the need for secondary noise suppression measures.

2. Extremely Low Pressure Pulsation & Vibration
The internal gear pump design provides exceptionally low pressure pulsation, dramatically reducing system vibration and preventing energy dissipation. The G55C series delivers performance comparable to more expensive piston pumps and internal gear pumps at a significantly more economical cost.

3. Wide Speed Range for Diverse Operating Conditions
With a speed range spanning 150 to 3000 RPM, the pump performs reliably across applications from low-speed high-torque to high-speed high-efficiency operations. Combined with 300 bar peak pressure capability, it meets the demands of conventional hydraulic systems as well as high-performance servo applications.

4. High Efficiency & Superior Contamination Tolerance
The internal gear pump design offers simple construction, excellent contamination tolerance, and typical volumetric efficiency exceeding 95%. Compared to piston pumps, it demonstrates greater tolerance to fluid contamination, resulting in lower maintenance costs and extended service life.

5. 100% Factory Testing Under Simulated Working Conditions
Every pump undergoes comprehensive performance verification on test benches that simulate actual operating conditions, including pressure-flow characterization, volumetric efficiency measurement, noise level assessment, and seal integrity testing—ensuring batch-to-batch quality consistency and reliability.

Expert Maintenance Tips

1. Model & Configuration Verification
Confirm that the pump model code matches your requirements, paying special attention to displacement (050/063/075/090), shaft type (parallel key FSBAC or spline FSBT), and rotation direction. Verify the nameplate specifications against your system design requirements before installation.

2. Port Cleanliness & System Flushing
Ensure the inlet port and suction lines are free from debris, metal chips, and contaminants before installation. Perform a thorough circulating flush of the entire hydraulic system to achieve cleanliness levels of NAS 1638 Class 9 or ISO 4406 18/15 or better.

3. Shaft Alignment
Verify the alignment accuracy between the pump shaft and the drive motor shaft. Ensure the connection produces no axial or radial loads. Use flexible couplings and maintain concentricity within 0.05 mm.

4. Inlet Pressure Monitoring
The G55C series requires inlet pressure to be maintained between 0.6 and 3 bar. Keep suction lines as short and straight as possible to minimize inlet resistance. Install a vacuum pressure gauge on the suction line for real-time monitoring.

5. Pre-Start Priming & Air Bleeding
Fill the pump cavity with hydraulic oil before installation. During initial start-up, loosen the drain port or outlet fitting to purge air from the system. Retighten only after continuous oil flow appears free of bubbles. Never operate the pump under dry suction conditions.

6. Fluid Cleanliness & Temperature Management
Maintain hydraulic fluid cleanliness to NAS 1638 Class 9 or ISO 4406 18/15 or better. Keep oil temperature within the -20°C to +80°C range. Replace filters regularly and monitor system oil cleanliness through routine sampling and analysis.
