Product Overview
The GR70SMT16B600L-RS/mpt 160/213 is a high-flow model in the Italian SETTIMA SMT16B series three-screw pumps, delivering 600 L/min (@3000 rpm) with a maximum working pressure of 40 bar. Since 1978, SETTIMA has been one of Europe’s leading manufacturers of screw pumps and is DIN/ISO 9001 certified, with the SMT16B series holding ATEX explosion-proof certification.
This three-screw pump consists of one driving screw and two driven screws housed within the pump body. The core advantage lies in the balancing piston on the driving screw, which eliminates axial loads through hydrodynamic unloading. The driven screws are hydraulically rotated by the fluid being pumped, eliminating mechanical wear. The pump is a fixed-displacement axial-flow rotary pump, where the mechanical balance between the three moving screws and the self-lubricating main bearings ensure low pressure pulsation, low noise, and long service life.
The pump is self-priming and can be installed in various spatial orientations. The “RS” designation indicates the inclusion of an adjustable safety valve (Regulated Safety Valve / adjustable pressure valve). “mpt 160/213” refers to the motor/mounting interface configuration, specifying the flange and drive interface.
Engineered as a direct OEM-replacement solution, the GR70SMT16B600L-RS/mpt 160/213 fully complies with SETTIMA original design standards and ISO 3019/2 mounting interface specifications, offering 100% direct interchangeability with OEM pumps. Every unit undergoes 100% workload simulation testing prior to shipment, rigorously validating pressure retention, flow rate, and internal leakage performance to meet or exceed OEM standards.

Key Technical Advantages
1. Three-Screw Hydrodynamic Balance Design – Zero Axial Load
The balancing piston on the driving screw eliminates axial loads through hydrodynamic unloading. The driven screws are hydraulically rotated by the fluid being pumped, eliminating mechanical wear. This design ensures long-term reliability under high-pressure conditions.
2. Ultra-Low Noise & Low Pulsation Operation
The mechanical balance between the three moving screws and the self-lubricating main bearings ensure extremely low pressure pulsation and low noise levels (52–68 dB(A)). Particularly suitable for industrial environments with strict noise and pressure stability requirements.
3. Wide Flow & Wide Viscosity Adaptability
Wide flow coverage with speed range of 500–3600 rpm (up to 6000 rpm) and viscosity support from 1–2000 cSt. Compatible with mineral oils (HLP/HLVP), vegetable oils (HETG/HEPG/HEE), emulsions (HFA/HFB), water-glycol (HFC), phosphate esters (HFDR), and high-viscosity lubricating oils.
4. Multiple Material & Seal Options – Strong Adaptability
Housing materials include aluminum alloy, cast iron, or carbon steel; rotor material is special hardened alloy steel. Seals可选 NBR, FPM (Viton), or EPDM. Flexible selection based on specific application conditions.
5. Integrated Adjustable Safety Valve – High System Integration
The “RS” designation indicates the inclusion of an adjustable safety valve. System pressure protection is achieved without additional valve blocks, simplifying hydraulic system design.
6. Self-Priming Design – Flexible Installation
The pump is self-priming and can be installed in various spatial orientations. Both standard shaft and hollow shaft options are available.
7. 100% Factory Tested & Direct Interchangeability
Every unit undergoes 100% workload simulation testing prior to shipment, covering pressure retention verification, flow validation, and internal leakage detection. Fully compliant with SETTIMA original design standards and ISO 3019/2 mounting flange specifications, 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
The GR70SMT16B600L-RS/mpt 160/213 belongs to the GR70 frame size with 600L/min flow (@3000 rpm) and 40 bar maximum pressure. The SMT16B series also includes GR20, GR25, GR32, GR40, GR45, GR55, GR60, GR70, GR80, GR90, GR110, and other frame sizes. Before installation, confirm the correct specifications based on system flow and pressure requirements, and verify the complete model code on the pump nameplate.
2. Rotation Direction Confirmation
The pump features clockwise rotation (viewed from the pump shaft end). Before installation, always verify that the drive shaft rotation direction matches the pump’s rotation direction—incorrect rotation will result in pump failure to prime.
3. Installation Precautions
Mounting flange standard: ISO 3019/2, front flange diameter 300 mm
Shaft diameter 32 mm, parallel key 10 mm
Suction port: 3 1/2″ SAE-3000, pressure port: 3″ SAE-3000
Maintain inlet pressure at 0.7 – 3 bar
Use SETTIMA-specified torque values for mounting bolts—avoid over-tightening which may cause housing distortion
The pump is self-priming and can be installed in various spatial orientations
4. First Start-Up and Bleeding
Before first start-up, must fill the pump with fluid 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
5. Fluid and Filtration
Recommended filtration: Suction 100μm / Pressure 10-25μm
Maintain fluid cleanliness to NAS 1638 Class 10 or ISO 4406 19/16
Maintain operating temperature within -20℃ to +180℃
Viscosity range: 1 – 2000 cSt
Regularly replace filters to prevent contaminants from entering the pump
6. Periodic Maintenance
Check mounting bolt torque every 1,000 operating hours
Regularly monitor system operating pressure—not to exceed 40 bar
Three-screw pumps are known for long service life and low maintenance requirements—nevertheless, regularly inspect mechanical seals to prevent leakage
If flow output decreases, noise levels increase abnormally, or system temperature rises excessively, inspect and replace worn components promptly
Note: This model is equipped with an adjustable safety valve (RS)—regularly verify the valve set pressure
