Product Overview
The GR40 SMT16B 1001 is a highly representative three-screw pump from SETTIMA—a renowned Italian manufacturer of screw pumps—within the GR SMT16B series. This series covers 14 sizes from GR20 to GR110, with flow rates ranging from 4 to 3,200 L/min and continuous operating pressures up to 40 bar (intermittent up to 50 bar). The GR40 model delivers a rated flow of 100 L/min.
The GR SMT16B series screw pumps are reliable, low-noise solutions for industrial applications requiring long service life and exceptionally smooth fluid flow. Their core advantages lie in pulse-free delivery, low-noise operation, and broad fluid and temperature compatibility.
As a professional hydraulic component manufacturer, we provide 100% interchangeable replacement solutions for the SETTIMA GR SMT16B series. Every GR40 SMT16B series screw pump undergoes 100% performance testing under simulated actual operating conditions—from flow accuracy and pressure stability to volumetric efficiency—fully benchmarked against SETTIMA original equipment standards.

Key Technical Advantages
1. Pulse-Free Delivery — Extremely Smooth System Operation
The GR SMT16B series screw pumps utilize the three-screw meshing principle, delivering fluid continuously along the axial direction—fundamentally eliminating pressure pulsation. Compared to external gear pumps, pressure pulsation is extremely low, effectively protecting valves, sensors, and actuators from hydraulic shock.
2. Ultra-Low Noise Operation (52–68 dB(A))
The GR SMT16B series screw pumps achieve noise levels of only 52–68 dB(A) (@ 2,950 rpm). The rolling motion of the screws suppresses vibration-induced noise, with no metal-to-metal impact during operation—particularly suitable for noise-sensitive workshops, laboratories, and medical equipment applications.
3. Ultra-Wide Viscosity and Temperature Range
The GR SMT16B series handles an exceptionally wide viscosity range from 2 to 10,000 cSt and fluid temperatures from -20°C to +180°C. This makes it ideal for transferring everything from low-viscosity fuels to high-viscosity lubricating oils across demanding applications with significant temperature variations.
4. High-Strength Materials — Extended Service Life
The pump body is manufactured from extruded aluminum alloy, with primary screws in steel and secondary screws in cast iron. Special applications offer core-hardened steel screws, surface-treated screws, stainless steel, and other options. Combined with the no axial load design between screws, pump service life is significantly extended.
5. Flexible Mounting and Configuration Options
The GR SMT16B series offers both dry (SMT16B) and submersible (SMIT16B) mounting options. Flanges conform to ISO 3019/2 standards, with SAE 3000 and BSPP connection options. Any mounting position is supported, greatly simplifying system integration.
6. ATEX Explosion-Proof Certification
SETTIMA has obtained ATEX certification for the SMT16B series, enabling safe operation in explosive environments such as petrochemical, chemical, and mining applications.

Expert Maintenance Tips
1. Verify Rotation Direction
Viewed from the shaft end, the GR SMT16B 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. Inlet Pressure Control
Minimum inlet pressure is -0.7 bar, maximum is 3 bar. Insufficient inlet pressure will cause cavitation, damaging internal pump components. Ensure suction lines are unobstructed and fluid viscosity is appropriate.
4. Filtration and Fluid Cleanliness
Screw pumps require proper fluid cleanliness. Recommended cleanliness level is NAS 1638 Class 8 or ISO DIS 4406 17/14. Install appropriately rated filters on the pump suction line and regularly inspect filter element condition.
5. Speed Range Control
The GR SMT16B series speed range is 500–3,600 rpm. Consult the manufacturer for speeds below 1,000 rpm or above 1,800 rpm. Never operate outside the specified speed range.
6. Pressure Limits
Continuous Operating Pressure: 40 bar
Intermittent Operating Pressure: 50 bar
Never exceed rated pressure—peak pressure is permitted for short-term transient conditions only
7. Seal Material Selection
Standard seal material is NBR. Based on fluid temperature and chemical compatibility, FKM is available for high-temperature applications, and EPDM for specific chemical media environments.
8. 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 GR SMT16B series features long design life with few wear parts and low maintenance costs.
