GR8B series three screw pump
1. Product overview:
GR 8B series three screw pumps for low pressure cooling and filtration up to 15bar The SMT8B three screw pumps are designed for heavy duty cooling and filtration applications. Their extremely compact design also allows them to be used in applications where there is no space for conventional progressive cavity pumps.
2. Product use function:
Three screw pumps of the GR 8B series are used in industrial and mobile applications for gearbox lubrication and lubrication services, power pack cooling, low pressure filtration, recirculation, hydroelectric power generation and wind turbines.
3.the scope of application :
1. Cooling: GR 8B pump and GR 16B pump, deliver the fluid from the heat source to the fan unit, where the 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.
Meet the needs of the cooling application market. Both pumps are specially designed, high-tech, high-efficiency, low-noise features of the product for use in fan coolers and more complex cooling oil refrigeration systems.
2. Filtration: The three-screw pump has a wide range of flow and can meet the requirements of any type and size of filtration equipment.
3. Low viscosity: suitable for low viscosity fluid processing applications, special technical processing enhances the self-lubrication of the mechanical surface;
4. Injection molding machine: Due to its very compact structure , it is very suitable for closed-circuit chillers and low-pressure filter units. The GR 16 B 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.
5. Extruder: Noiseless, low-pulsation screw rotor pumps are ideal for use in applications such as presses where noise reduction is critical .
6. Machine tools: GR series products are very suitable for various applications of cooling, lubrication and cleaning.

7. Advantages:
1. SAE3000 flange adapter: flange load designed according to API standard ;
2. The design of the integrated pump lining and the separate design of the pump lining fully meet the requirements of Chapter 3 of API 676 ;
3. Multiple options for the material of the driven screw: wear-resistant ductile iron, nitrided steel ; ensure the best operating performance under critical conditions ;
4. A single mechanical seal only bears suction pressure, and API 682 packing seal is optional ;
5. Special nano-coating and magnesium-aluminum alloy or copper-aluminum composite die-casting scheme ensure a wider range of viscosity of the conveying medium ;
6. The arrangement of axial and radial oil inlets ensures the needs of various working conditions on site ;
7. There is only one bearing, which can be lubricated by built-in medium or lubricated by external grease ;
8. The hydraulically balanced rotor does not need thrust bearing ;
9. Quiet work without pulsation ;
10. Convex shaft /concave shaft design , the installation space is not limited ;
11. Simple and lightweight process design , more cost -effective ;
