Product Description
Product Overview:
The GR45SMT16B210L is a high-performance, three-rotor screw pump engineered specifically for industrial fluid systems that demand “zero pulsation, ultra-quiet operation, and extended lifespan.” Covering a comprehensive range of frame sizes from GR20 to GR80, this series is designed to provide remarkably stable fluid power for heavy-duty lubrication, cooling, and filtration circuits. As a premium replacement solution for industrial B2B clients, this pump is benchmarked against the Settima SMT16B series in both engineering design and manufacturing tolerances. We guarantee Absolute Interchangeability—allowing customers to achieve seamless drop-in replacement without altering flanges, port configurations, or mounting brackets. Every single screw pump undergoes 100% automated simulated load testing prior to dispatch, ensuring exceptional reliability and minimal heat generation under continuous operation, thereby drastically reducing maintenance costs and downtime risks for your enterprise.

Material Construction: High-strength special cast iron body with surface-hardened, premium carbon steel rotors
Key Technical Advantages
Zero Pulsation & Ultra-Quiet Operation: Utilizing a highly precise screw profile design, the driving and driven rotors form continuous, closed sealing chambers. Fluid is propelled axially at a constant velocity, fundamentally eliminating fluid pulsation and keeping mechanical noise exceptionally low (typically under 65 dB(A))—making it ideal for silent hydraulic power units.
100% Seamless Drop-in Replacement: Flange dimensions, shaft extensions, and port sizes strictly adhere to the original equipment standards. Whether upgrading a system or conducting aftermarket maintenance, clients benefit from plug-and-play installation, bypassing expensive and time-consuming piping modifications.
Extended Lifespan & High Volumetric Efficiency: The idler rotors are driven entirely by fluid pressure, ensuring zero direct metal-to-metal friction between them and the driving rotor. Coupled with high-frequency induction hardened materials, this significantly prolongs the pump’s service life and sustains excellent volumetric efficiency even under full 40 bar loads.
Rigorous 100% Simulated Load Testing: We reject random batch testing. Before leaving our facility, every GR series screw pump is subjected to continuous rated pressure loads, temperature rise monitoring, and flow calibration on automated test rigs, guaranteeing true battle-ready performance right out of the box.
Application Areas
Thanks to its exceptionally smooth and shock-free fluid delivery, the GR45SMT16B210L is heavily utilized in high-demand industrial applications:
Wind Energy Systems: Forced lubrication and cooling circuits for wind turbine gearboxes.
Industrial HPUs: Kidney loops (offline cooling and filtration circuits) for large presses and CNC machinery.
Heavy Machinery Lubrication: Hydrostatic bearing lubrication in metallurgical equipment, paper mills, and massive industrial compressors.
Energy & Petrochemical: Lube oil systems for hydro-turbine governors, fuel oil transfer, and low-pressure fluid boosting.
Expert Maintenance Tips
Strictly Prevent Dry Running: The internal precision components of a three-screw pump rely entirely on the pumped medium for lubrication. Prior to initial startup or after a long shutdown, the pump casing must be fully primed with clean fluid. Running dry, even for a few seconds, will cause instantaneous rotor seizure.
Maintain Fluid Cleanliness: Due to the micron-level meshing clearances between the screws, we highly recommend maintaining a filtration level of ISO 4406 19/17/14 or better on the return or kidney loop. This prevents hard particulates from scoring the rotor profiles.
Precision Shaft Alignment: Although the pump runs smoothly, the drive shaft cannot tolerate excessive radial or axial loads. A flexible coupling is mandatory, and the concentricity alignment between the pump shaft and the motor shaft must be kept within a strict 0.1mm tolerance to avoid abnormal vibration or premature shaft seal leaks.
