Product Overview: G Type Single Screw Pump

The G-type single screw pump is widely used in developed countries, and it is commonly referred to as "MONOPUMPS" or "Mono Pump" overseas, while in Germany, it is known as "eccentric rotor pump." Due to its excellent performance, its application range in China has been rapidly expanding in recent years.

Its primary features include strong adaptability to media, stable flow, minimal pressure pulsation, and high self-priming capability, which are unparalleled by any other type of pump.

Our company has conducted analysis and research on G-type single screw pumps produced in foreign countries (such as Germany, the UK, France, Japan, etc.) and domestic products in the same industry, drawing on the strengths of both to continuously innovate and improve our own products. Currently, our products have formed a complete system, with pressure ranging from 0.6 to 1.2 MPa, and special requirements can reach up to 3 MPa, meeting the diverse needs of a wide range of users for single screw pumps.

Our company's screw pump is of reliable quality, comes with a three-year warranty, and is offered at a competitive price. We also ensure the normal supply of spare parts and accessories.

We eagerly serve a wide range of customers, accepting design and manufacturing assignments for single screw pumps that meet their specific requirements.

II. Product Features of G Type Single Screw Pumps:

The G-type single screw pump is a new type of pump that operates according to the reciprocating meshing volumetric principle. Its main working components are the eccentric screw (rotor) and the fixed sleeve (stator). Due to the special geometric configuration of these components, they form separate sealed cavities. The medium flows uniformly in an axial direction. The internal flow velocity is low, and the volume remains constant. Pressure is stable, thus preventing vortex and turbulence. The G-type single screw pump is widely used in various industries for conveying a variety of media, operating continuously at a constant pressure with no pulsation, and ensuring undamaged medium transport. Flow rate is adjusted by varying the speed to achieve metering. The G-type single screw pump is suitable for transporting media with the following characteristics: high solid content (maximum particle size up to 150mm) or no solid content | media with various viscosities (1mPas to 3 million mPas) | thixotropic and easily expandable media | shear-sensitive media | erosive media | media with or without self-lubrication | corrosive media (pH=0-14) | adhesive media | toxic media | high flow rates and high pressures · Flow range from a few milliliters per hour to 500m3 (2200gpm) · Pressure range up to 48bar, special designs can reach 72bar. The same drive component can be matched with four different designs of rotors/stators, providing you with the best operational solution.

G-type single screw pumps are designed for various applications, utilizing different metals such as cast iron, nickel-chromium steel, acid-resistant materials, Hastelloy, and titanium alloys. Elastic materials include wear-resistant, oil-resistant, acid-resistant, and alkaline-resistant rubbers like natural rubber, nitrile rubber, ethylene propylene rubber, and fluoro rubber. For highly erosive media, ceramic or plastic materials can be used. In cases where the medium cannot be used with elastic materials due to high temperatures or certain chemical components, rigid or rigid rotor designs are available. Various shaft sealing options: according to customer requirements, mechanical seals range from single face seals (with or without quick release) to double face seals (face-to-face and series-type mechanical seals); also available are box seals. Other options include packing seals, water seals, and special seals. Leak-free magnetic drive is available for toxic media.

Performance Features:

· Maximum suction lift height up to 6 meters of water column

· Bi-directional rotation, bidirectional conveyance (requires a reversing stator)

Flexible installation options.

·Smooth, stable operation; low noise; pulse-free; shear-free

·Temperature range of conveying medium: -20℃ to +150℃

·The G-type single screw pump has fewer parts, a compact structure, a small size, easy maintenance, and the rotor and stator are the vulnerable parts of this pump, with a simple design for easy assembly and disassembly. Transmission can be achieved through a direct coupling or by using a variable-speed motor, V-belt, and transmission box, etc., for speed variation. Shanghai Aofeng Valve & Pump Manufacturing Co., Ltd. is a professional manufacturer specializing in the production, design, and manufacturing of single screw pumps. Different screw pumps have varying specific application scenarios.
