Key Technical Advantages
1. CONTINUUM® Continuous Flow Technology — Pulse-Free Delivery
The G55C series features SETTIMA’s patented CONTINUUM® (continuous flow) technology. Unlike conventional gear pumps, the continuous meshing motion of the screws fundamentally eliminates pressure pulsation, achieving ultra-low pulsation (< 1–2%) fluid delivery. This characteristic effectively protects valves, sensors, and actuators from hydraulic shock, significantly improving system stability and precision.
2. Ultra-Low Noise Operation (< 68 dB) — Silent and Energy-Efficient
The G55C series servo pump operates at exceptionally low noise levels, far below conventional gear pumps. The rolling motion of the screws suppresses vibration-induced noise with no metal-to-metal impact during operation—particularly suitable for noise-sensitive injection molding workshops, medical equipment, and precision manufacturing environments. The aluminum alloy housing further enhances heat dissipation and vibration damping.
3. Ultra-Wide Speed Range (150–6,500 rpm) — Perfect for Servo Systems
The G55C series offers an exceptionally wide speed range from 150 to 6,500 rpm. Stable flow output is maintained at low speeds, while ample flow is delivered at high speeds. This characteristic makes it the ideal partner for servo motor drives, enabling real-time speed and flow adjustment based on load demands for on-demand oil supply and significant energy savings.
4. High-Strength Aluminum Alloy Housing — Lightweight and Corrosion-Resistant
The G55C series pump body is manufactured from high-strength aluminum alloy, offering lightweight construction, corrosion resistance, and excellent heat dissipation. With total weight of only approximately 30 kg, low mechanical inertia, and fast response, it is particularly suitable for weight-sensitive mobile equipment and high-speed servo systems.
5. Excellent Fluid Compatibility and Extended Service Life
The G55C series handles a wide viscosity range of hydraulic and lubricating oils, with operating temperatures from -20°C to +150°C. Combined with the no axial load design between screws, pump service life is significantly extended. The full series is compatible with traditional gear pump mounting dimensions, facilitating equipment upgrades and retrofits.

Expert Maintenance Tips
1. Verify Rotation Direction
Viewed from the shaft end, the G55C series pump’s standard rotation is clockwise. For counter-clockwise rotation, contact SETTIMA for custom configuration. Always verify alignment with the drive motor’s rotation before installation. Reverse operation is strictly prohibited.
2. First Start-up and Priming
Screw pumps have self-priming capability, but ensure the pump cavity is fully primed before first start-up. Never start the pump dry—this will cause severe wear or seizure of screws and bushings.
3. Fluid Cleanliness Management
Screw pumps require proper fluid cleanliness. Install appropriately rated filters on the pump suction line and regularly inspect filter element condition. Recommended cleanliness level is NAS 1638 Class 8 or ISO DIS 4406 17/14.
4. Speed Range Control
The G55C series speed range is 150–6,500 rpm. In servo system applications, set the speed range appropriately based on load demands to avoid prolonged operation at extreme speeds.
5. Pressure Limits
Rated Operating Pressure: 250 bar. Never exceed rated pressure—peak pressure is permitted for short-term transient conditions only (single occurrence < 10 minutes).
6. Seal Material Selection
Standard seals are suitable for conventional hydraulic oils. Based on fluid temperature and chemical compatibility, FKM is available for high-temperature applications, and EPDM for specific chemical media environments.
7. Regular Inspection and Maintenance
Regularly inspect the system filter element condition. Regularly monitor the pump for abnormal operating noise—if abnormal noise or system pressure drop is detected, shut down immediately for inspection. The SETTIMA G series features long design life with few wear parts and low maintenance costs. In servo system applications, a comprehensive inspection every 2,000 operating hours is recommended.
