High flow : After uninterrupted testing, to meet the requirements of efficient and safe handling of high flow;
Low viscosity : suitable for low viscosity fluid handling applications;
High Viscosity : Specific solutions have been designed and tested to handle high viscosity liquids quietly, safely and with maximum efficiency; specifically designed to deliver very high viscosities (up to 100.000 cSt), very low temperatures (down to -50°C) and oils - Fluid of air emulsion.
Fuel oil : GR 16 B series three screw pumps are designed for maximum efficiency in fuel oil handling, as well as durability and resistance of components to fluid impurities; perfect lubrication of diesel engines, gas and steam turbines, industrial boilers (up to 90 bar) , circulation and conveying solutions. Also suitable for handling sulfur-free fuels such as DMX.
3. the scope of application :
1. Hydraulic power : Hydraulic or fluid power includes the use of fluids under pressure to control and transmit power;
More specifically, power is transmitted through a controlled circulation of a pressurized fluid (usually oil) to a motor or cylinder, which converts it into mechanical force for specific workloads in a variety of industrial machinery and mobile applications. Fluid power is widely used in mobile applications (forklifts, electric /hybrid vehicles, etc.), but fluid power is also used in industrial automation, where tools or workpieces are moved or fixed using hydraulic power, such as: machine tools, presses, plastic injection molding machines .
2. Lubrication : Lubrication includes the use of lubricants to reduce friction and avoid wear and corrosion of mechanical surfaces;
Lubrication systems are critical components in all industrial and mobile machinery, protecting gears from wear and corrosion, reducing friction, and transferring heat away from the moving parts of the machine. The lubrication pump delivers the lubricant from the oil reservoir to the piping system of the centralized lubrication system. Lube oil applications require pumps that feature reliability and extended life with minimal maintenance. A typical lube pump must also be able to operate over a wide temperature and viscosity range.
3. Cooling : Cooling is the process of transferring heat/cold between fluids .
The GR16B series three screw pump is used to deliver fluid from a heat source to a fan unit where air cools the fluid. Chillers are compact fan cooling units for small, simple circuits and are often preferred when heat dissipation is low, such as on pump test benches. For example, in machine tool applications, coolers are used when heat dissipation is high.
4. Filtration : The GR16B series three-screw pump has a wide range of flow and can meet the requirements of any type and size of filtration equipment.
Equipment used to control oil contamination levels from particulate matter, water and other degradation products, from fine filters to oil purifiers.
5. Conveying: GR16B series three-screw pump has a wide range of flow, temperature and viscosity, which is very suitable for handling various fluids
The GR16B series three-screw pump has a wide flow range and is suitable for handling various high /low temperature and viscosity hydraulic oils according to customer requirements.
They are commonly used for pumping lube /hydraulic/fuel oil in hydraulic systems, machines, engines, turbines , and in upstream and midstream installations for use at extraction points, storage centers, sorting Connection, loading and unloading between centers, treatment plants and refineries.
1. Energy and Electricity
① The success of the power generation industry is the result of continuous technological innovation aimed at providing quality products and high energy savings.
② Pumps for conveying and loading various types of oils and lubricating fluids, covering the lubrication, filtration and cooling requirements of turbines and compressors, wind turbines.
③Widely used in feed and injection systems of burners, corrosive liquids and oils at high temperatures, or in-line solutions in seal oil systems to transfer a portion of lubricating oil to seals to ensure no gas leakage.
④Applied to the lubrication of wind turbine gearboxes, able to meet the many challenges posed by this very demanding installation.
2. Oil and gas
Suitable for conveying, circulating and mixing low- and high-viscosity clean liquids with lubricating properties, such as oils, crude oils and fuel oils, as well as medium-viscosity lubricating oils, fuels or paraffins.
3. Rubber and plastic
The three-screw pump is designed for low pressure applications and due to its very compact size is ideal for closed circuit chillers as well as low pressure filter units. The GR16B is suitable for medium pressures up to 40 bar for larger filtration systems and more powerful cooling units for pumping cryogenic cooling oil from the reservoir to the injection machine.
4. Hydraulic machinery
The GR 16 B series three screw pumps are noiseless, low pulsation screw rotor pumps ideal for use in applications such as presses where noise reduction is critical. Presses need to operate at very high pressures and possibly high flows, often without sound barriers. Therefore, it is of the utmost importance that the pump not only provides adequate performance, but also minimizes noise emissions to ensure a safer, quieter and more comfortable workplace, thereby increasing efficiency and productivity.
5. Mining industry
① Reliable pumps are required for a variety of demanding and challenging applications
② Represents an advanced, safe, reliable and efficient solution for major mining equipment such as mine dump trucks, drilling rigs, scrapers, conveyors...
6. Machine tools
The GR range is ideal for cooling, lubricating and cleaning applications.
7. Compressors and rotating equipment
Noise-free, low-pulsation rotary lobe pumps are ideal for use in applications such as presses where noise reduction is critical.
8. Ships at sea
G R16B series three-screw pumps are widely used in conveying, filtering, cooling and feeding of diesel engines, gas turbines and marine boilers.
