GR472V28CCFSAEBAACODB Settima Screw Pump | 28cc 300 bar

Product Overview

The GR472V28CCFSAEBAACODB, GR47-2V-028CC-FSAEBAC-O-DX, GR282V004CCF1AC3BAB, and G55C090FSBT are representative models of the Italian SETTIMA GR series and G55 series high-pressure silent hydraulic pumps. Headquartered in Piacenza, Italy, SETTIMA is one of Europe’s leading hydraulic pump manufacturers.

The SETTIMA GR series features helical rotor (Continuum®) technology, with a compact design similar to standard gear pumps but utilizing angled gears instead of spur gears for continuous meshing, significantly reducing noise and pulsation. The GR series delivers an average of approximately 15 dB(A) lower noise and approximately 75% lower pulsation than standard external gear pumps. While providing power up to 300 bar, noise levels remain as low as 68 dB. The G55C090FSBT belongs to the G55 series with 90 cc/rev displacement.

Engineered as a direct OEM-replacement solution for SETTIMA original products, these models fully comply with SETTIMA original design standards and SAE/ISO mounting interface specifications, offering 100% direct interchangeability. Every unit undergoes 100% workload simulation testing prior to shipment, rigorously validating pressure retention, volumetric efficiency, and internal leakage performance to meet or exceed OEM standards.

Key Technical Advantages

1. Helical Rotor Technology – Ultra-Low Noise Operation
The SETTIMA Continuum® system utilizes angled helical rotors instead of traditional spur gears for continuous meshing. The series delivers an average of approximately 15 dB(A) lower noise than standard external gear pumps, maintaining just 68 dB while providing 300 bar power. Eliminates the need for expensive secondary sound insulation measures.

2. Extremely Low Pressure Pulsation – Suitable for Precision Control
Pulsation levels are reduced by approximately 75% compared to conventional pumps. The extremely low flow and pressure pulsation make it ideal for injection molding machines, die casting machines, and servo electro-hydraulic systems with stringent pressure stability requirements.

3. Superior High-Pressure Capability
The GR47 series delivers maximum pressure up to 300 bar with continuous pressure of 270 bar. The GR28 series delivers up to 275 bar. The G55C090FSBT delivers up to 270 bar. High-strength materials and precision machining ensure long-term stability under high-pressure conditions.

4. Fully Interchangeable with Standard Gear Pumps
The SETTIMA GR series features compact dimensions similar to standard gear pumps. Mounting dimensions are fully compatible with standard external gear pumps, allowing easy replacement of existing pump units without piping or mounting modifications.

5. Wide Speed Range & High Efficiency
The GR series supports a wide speed range of 150–6500 r/min. Volumetric efficiency reaches up to 96% (@1500 r/min). Suitable for both fixed-speed and variable-speed drives, including servo variable-frequency drive systems.

6. 100% Factory Tested & Direct Interchangeability
Every unit undergoes 100% workload simulation testing prior to shipment, covering pressure retention verification, internal leakage detection, and flow validation. Fully compliant with SETTIMA original design standards, with flange dimensions, shaft specifications, and mounting interfaces identical to OEM pumps—direct drop-in replacement with zero modifications required.

Expert Maintenance Tips

1. Model Confirmation
GR472V28CCFSAEBAACODB and GR47-2V-028CC-FSAEBAC-O-DX are different configuration codes for the GR47 series 28 cc/rev displacement. The GR47 series offers displacements from 28 to 50.3 cc/rev. The GR28 series offers displacements from 4.2 to 12.9 cc/rev. Before installation, confirm the correct displacement based on system flow requirements and verify the complete model code on the pump nameplate.

2. Rotation Direction Confirmation
GR472V28CCFSAEBAACODB features clockwise rotation. Before installation, always verify that the PTO rotation direction of the host machine matches the pump’s rotation direction—incorrect rotation will result in pump failure to prime and may cause severe damage to internal components within a short period.

3. Installation Precautions

• Thoroughly clean the mounting flange (recessed flange, pilot diameter 50.8 mm) and tapered shaft 1:8 mating surfaces

• Use SETTIMA-specified torque values for mounting bolts—avoid over-tightening which may cause housing distortion

• Ensure correct connection of inlet, outlet, and drain ports

• The GR series features compact dimensions fully compatible with standard gear pump mounting

4. First Start-Up and Bleeding

• Before first start-up, must fill the pump with hydraulic oil through the inlet port—never start dry

• After start-up, run at low speed with no load for 2–3 minutes to ensure complete air evacuation from the system

• Check for abnormal noise or leakage—while helical rotor pumps are quieter, they remain sensitive to cavitation

5. Fluid and Filtration

• Use high-quality anti-wear hydraulic oil compliant with DIN 51524 standards

• Recommended viscosity: 12–100 cSt

• Maintain operating temperature within recommended range

• Maintain system oil cleanliness to ISO 4406 18/15 or better

6. Periodic Maintenance

• Check mounting bolt torque every 1,000 operating hours

• Regularly monitor system operating pressure—GR47 series not to exceed 300 bar (270 bar continuous); GR28 series not to exceed 275 bar

• Helical rotor pumps are known for long service life and low maintenance requirements—nevertheless, regularly inspect shaft seals to prevent leakage

• If flow output decreases, noise levels increase abnormally, or system temperature rises excessively, inspect and replace worn components promptly
