3.Marine/Offshore engineering:For handling Lubricating oil, hydraulic oil, light and heavy fuel oil. e.g. as main lubricating pump, auxiliary lubricating pump, emergency lubricating pump for marine diesel engine. As a fuel supply pump, it is used as a fuel supply pump and a heavy oil injection pump on the Marine boiler to provide power sources for the ship, such as the anchor mechanism dynamic pump and the steering engine steering drive pump

4.General industrial engineering/machine/heavy machine industry:For handling lubricating , cooling ,sealing and regulating. e.g. as lbricating oil pump, Lubricate and cool the machinery; e.g. for steam , gas and water turbines as crculating oil pump, regulating oil pump, control oil pump and jacking oil pump; for compressors as turbine oil pump,sealing oil pump and coolant oil pump; for diesel engine as lubricating oil pump and fuel pump, etc

5.Offshore engineering:For handling lubricating. cooling and hydraulic oils, light and heavy fuel oils, crude oils as well as fuels. e.g. for offshore drilling platform as lubricating oil pump , the hydraulic system is lubricated, circulated and cooled

6.Tank farms:For handling all lubricating fluids such as greases,oils, paints, fuels, polyols，isocyanates;e.g. as loading or unloading pumps.

7.Chemical and petro-chemical as well as processing industry:For handling all lubricating fluids such as oils (including crude oils), greases, paint, lacquers, ointments, pastes, polyols，iso­cyanates, tar, bitumen, glycerin, glues, adhesive substances, resins,paraffins, waxes. water glass and also as pipeline pumps

8.Tire rubber/printing/paper industry:For handling aromatics oil, gravure ink, rubber oil, and pulp. e.g. for aromatics oil pump as Rubber factory

Product Advantages

1.The A3MG screw pump utilizes the hydraulic balance principle to divert the medium from the high-pressure zone to the low-pressure area, counteracting the axial force on the screw and preventing screw wear, thereby extending its service life.

2.The A3MG screw pump is equipped with a safety valve that effectively controls pump overload or pipeline overload.

3.The A3MG screw pump features 5 positioning bushings (made of copper), ensuring stable operation and providing stronger cavitation resistance.

4.The A3MG screw pump’s bushing is made of aluminum-clad copper, a material with higher wear resistance, making it suitable for the transportation of low-viscosity media (such as diesel and fuel oil).

5.The screw is the core of the pump. The A3MG screw is made using a special processing technique that enhances the screw’s hardness, tensile strength, smoothness, and precision. During the transportation of media, it effectively establishes an oil film, which is fundamental to ensuring the pump’s operational lifespan.

6.The A3MG screw pump provides a pump core assembly for easy maintenance, reducing costs.

7.The A3MG screw pump features interchangeable positions for the safety valve and the base, allowing for easy adjustment of the inlet and outlet oil directions. Additionally, to accommodate complex on-site installation requirements, various structural forms have been designed to meet installation needs.

Instructions for use

Before starting for the first time, please fill the lubricating medium oil to ensure that a good oil film is formed on the surface of the screw pair and spiral groove. If you want to make the service life of the screw pump longer, the following points are very important

1.It is strictly forbidden to tighten the import and export connection flange, so that the base pump body deformation and displacement, damage the inherent accuracy of the pump

2.When configuring the pipeline, it is strictly forbidden to damage the coaxial tightness of the pump and the motor to ensure the reliable sealing of the import and export pipeline connection.

3.During installation, the rubber plug of the inlet and outlet must be removed, and any impurities and welding slag must not enter the pump chamber.

4.It is strictly prohibited to operate or use water media without media. Or use other media to clean the pump.

5.Long unused and before the first start, the pump cavity must be filled with the use of media.

6.The pipe diameter configuration must be consistent with the pump diameter. The inlet and outlet pipe valves must be opened when starting.

7.It is strictly prohibited to use pressure exceeding the rated working pressure of the pump.

8.Do not adjust the safety valve adjusting bolts, which have been adjusted before delivery. The safety valve cannot be used as an relief valve

9.It is strictly prohibited to disassemble the pump parts without the written permission of the manufacturer

10.Screw pump is a positive displacement quantitative pump, its working pressure depends on the system load.
