Settima Type Hydraulic Screw Pump | GR55, GR32, GR25 | SMT16B Low Noise Pump

GR & SMT Series High-Performance Hydraulic Three-Screw Pumps

Product Overview: The GR and SMT16B Series represent the industry gold standard for “silent operation” in hydraulic systems. As precision positive displacement three-screw pumps, this series is engineered specifically for applications demanding low pulsation and ultra-low noise levels. This featured range includes core specifications such as the compact GR25 and GR32, the high-capacity GR55, and the premium SMT16B-75L and SMT16B-30L screw units. The unique screw profile design ensures smooth, continuous axial fluid delivery, completely eliminating the fluid ripples associated with traditional gear pumps.

Key Technical Advantages:

• Ultimate Silence & Zero Pulsation: The sealed chambers formed by the three meshing screws move at a constant axial velocity, ensuring a flow as smooth as a river. Noise levels are typically 15-20 dB lower than equivalent gear pumps.

• Superior High-Speed Capability: Optimized hydrodynamic design supports operational speeds exceeding 3600 RPM, allowing for direct coupling with high-speed motors without reduction gears.

• High Volumetric Efficiency: High-precision ground screw sets combined with axial pressure balancing maintain exceptional efficiency even in medium-to-high pressure environments of 4-8 MPa.

• Extended Service Life: Relying on the pumped media (lubricants or hydraulic oils) for hydrodynamic lubrication, there is virtually no mechanical contact wear between screws, drastically reducing long-term maintenance costs.

• Target Applications: CNC machine tool coolant circulation, wind turbine lubrication, elevator hydraulic power units, fuel injection systems, and industrial oil cooling stations.
