G-type Single Screw Pump Product Introduction:

The G-type single screw pump produced by Haitan Pump Industry has been widely used in developed countries. Most foreign countries refer to single screw pumps as "Mono pumps" or "MONOPUMPS", while Germany refers to them as "eccentric rotor pumps". Due to its excellent performance, its application scope in China has been rapidly expanding in recent years. Its characteristics are strong adaptability to the medium, stable flow rate, small pressure pulsation, and high self-priming ability, which cannot be replaced by any other pump type. We have conducted analysis and research on single screw pumps produced abroad (such as Germany, England, France, Japan, etc.) and products in the same industry domestically, drawing on the strengths of others and continuously reforming and innovating our own products. At present, our company's products have formed their own system, with a pressure of 0.6~1.2MPa and a special requirement of up to 3MPa, which can meet the different needs of users for single screw pumps. The pumps produced by our unit have reliable quality, implement three guarantees, and relatively low prices, while ensuring the normal supply of spare parts. Our unit warmly serves our customers and accepts the design and manufacturing tasks of single screw pumps with special requirements from customers

Model meaning of G-type single screw pump:

Working principle and characteristics of G-type single screw pump:

The G-type single screw pump is a new type of pump that operates based on the principle of rotary meshing displacement. The main working components are eccentric screws (rotor) and fixed bushings (stator). Due to the unique geometric opening of this component, separate sealed chambers are formed. The medium flows uniformly in the axial direction. The internal flow rate is reduced while the volume remains unchanged. The pressure is stable, so there will be no product turbulence or agitation. Single screw pumps are widely used in various industries to transport various media, with constant pressure continuous operation, no pulsation, and no damage to the media transportation. By adjusting the speed to change the flow rate, the purpose of measurement can be achieved. This product is suitable for conveying media with the following characteristics: high solid content (particle size up to 150mm) or no solid content | media with various viscosities (1mPas-3 million mPas) | thixotropic and easily expandable media | shear sensitive media | abrasive media | media with/without self-lubricating properties | corrosive media (pH=O-14) | adhesive media | toxic media | high flow rate and pressure. The flow rate range is from a few milliliters per hour to 500m3 (2200gpm). The pressure range can reach 48bar, and special design can reach 72bar. The same transmission component can be matched with four different designs of rotors/stators, providing you with usage solutions. Different metal materials are selected for different application fields, ranging from cast iron and nickel chromium steel to acid resistant materials, Hastelloy alloys, and titanium alloys. Elastic materials can be selected from wear-resistant, oil resistant, acid resistant, and alkali resistant rubber, such as natural rubber, nitrile rubber, ethylene propylene rubber, and fluororubber. For highly abrasive media, ceramics or plastics can be used. When the medium cannot be made of elastic materials due to high temperature or certain chemical components, hard or rigid stators can be used. Various forms of shaft seals: According to customer requirements, mechanical seals range from single end face seals (with or without emergency treatment), double end face seals (back-to-back and series mechanical seals) to box seals; Packing seals, water seals, and special seals can also be used. Can provide leak free magnetic transmission for toxic media.

Performance characteristics of G-type single screw pump:

·Suck up to a height of 6 meters of water column
·Can rotate and transport in both directions (requires reverse stator)
Flexible installation method
·Smooth and stable operation, low noise, no pulsation, and no shear
·Temperature range of conveying medium -20 ℃~+150 ℃
·Single screw pump has few parts, compact structure, small volume, and easy maintenance. The rotor and stator are vulnerable parts of this pump, and the structure is simple and easy to assemble and disassemble. Transmission can be achieved directly through couplings, or through devices such as variable speed motors, V-belts, gearboxes, etc. Haitan Pump Industry is a professional manufacturer that manufactures, designs, and produces single screw pumps. Different screw pumps have different specific usage scenarios.

Main uses of G-type single screw pump:

1. Environmental protection: transportation of industrial wastewater, domestic wastewater, and sewage containing solid particles and short fibers. Especially suitable for oil-water separators, plate and frame filter presses, and other equipment.
2. Shipbuilding industry: transportation of media such as bottom cleaning, oil-water, oil residue, and oily water.
3. Petroleum industry: transporting crude oil. In recent years, it has been particularly successful to extract a mixture of crude oil and water up to a depth of one kilometer underground, as well as a mixture of coal gas and water in coal fields, greatly reducing the cost of mechanical oil extraction and coal mining. When the oil field reaches the later stage, screw pumps are used to inject polymers into the formation to increase oil recovery.
4. Medicine and daily chemical products: transportation of various adhesive pastes, emulsions, ointments and cosmetics.
5. Food canning industry: transportation of various viscous starches, cooking oils, honeycomb, sugar sauces, fruit pulp, cream, fish mince, meat mince, and their by-products.
6. Brewing industry: various fermented viscous liquids, strong liquor tanks, grain product residues, various sauces, slurries, and mucilages containing solid substances.
7. Construction industry: spraying and conveying of cement mortar, lime slurry, coatings, and their paste like forms.
8. Mining industry: The underground and slurry water containing solid particles in mines are discharged to the surface.
9. Chemical industry: various suspensions, oils, various colloidal slurries, various adhesives.
10. Printing and papermaking industry: transportation of high viscosity ink, PVC polymer plastic paste for wallpaper, and various concentrations of pulp and short fiber pulp.
