G Series Single Screw Pump

Product Name: G Series Single Screw Pump

Product Overview:The G Series Single Screw Pump, also widely known as a Mono Pump or Eccentric Rotor Pump, is a highly versatile rotary positive displacement pump. It is specifically engineered to handle the most challenging fluid transfer tasks across a vast range of industries. Whether dealing with highly viscous liquids, abrasive slurries, or media containing solid particles and fibers, the G Series delivers exceptional performance with a steady, low-pulsation flow. Its superior media adaptability and robust design make it a reliable workhorse in environmental protection, petroleum, chemical processing, food production, and many other industrial sectors.

Key Features & Structural Advantages:

• Unmatched Media Adaptability: The standout feature of the G Series is its ability to transport an incredibly diverse range of fluids. It handles viscosities ranging from clear water to extremely thick pastes (up to 200,000 cP or higher) with ease. It is also perfectly suited for liquids containing solid particles, suspended fibers, and abrasive impurities without clogging or damaging the medium's intrinsic structure.

• Smooth, Low-Pulsation Flow: Operating on the progressing cavity principle, the pump features a single-helix rotor turning inside a double-helix stator. This creates sealed chambers that move axially to push the fluid forward, resulting in a continuous, exceptionally steady flow with minimal pressure pulsation and vibration.

• Excellent Self-Priming Capability: The G Series boasts a powerful self-priming ability, typically achieving a suction lift of up to 6 meters. This allows for quick and hassle-free startup without the need for complex pre-filling systems, significantly improving operational efficiency.

• Compact & Easy Maintenance: Designed with a simple and compact structure, the pump has fewer parts compared to other industrial pumps. The rotor and stator are the main working components and are designed for easy disassembly and replacement, which minimizes downtime and keeps maintenance costs low.

• Flexible Material & Drive Options: To suit different working conditions, the pump offers highly customizable configurations. The flow rate can be precisely adjusted by changing the motor speed (compatible with variable speed drives). Furthermore, wetted parts can be manufactured from various materials, including cast iron, stainless steel (304, 316, 316L), and a wide selection of stator rubber compounds (such as NBR, EPDM, and FKM) to resist specific chemical corrosions and temperatures.

Technical Specifications:

• Flow Rate: Highly customizable based on model and speed (typically ranging from 0.8 to over 100 m³/h)

• Pressure Rating: Standard single-stage up to 0.6 MPa; Multi-stage configurations available up to 2.4 MPa or higher for special requirements

• Viscosity Range: Capable of handling viscosities from 1 mPa·s up to 200,000 cP (centipoise)

• Solid Handling: Excellent at passing solid particles and fibrous materials commonly found in sludge, pulp, and wastewater

• Temperature Limit: Standard models typically up to 120℃; high-temperature variants available up to 150℃

• Material Options: Rotor (Cast Iron, Stainless Steel 304, 316, 316L); Stator (Various high-quality rubber compounds like NBR, EPDM, FKM)

Typical Applications:

• Environmental Protection: Ideal for transporting industrial sewage, domestic wastewater, sludge, and flocculants in water treatment plants due to its clog-resistant design.

• Petroleum & Chemical Industry: Widely used for crude oil, heavy oil, polymers, resins, acids, alkalis, and various abrasive or corrosive chemical suspensions.

• Food & Beverage Industry: Perfect for sanitary transfer of high-viscosity products like honey, syrups, dairy products, fruit pulps, starch, and alcoholic beverages without altering their quality.

• Paper & Pulp: Excellent for conveying paper pulp, black liquor, high-viscosity inks, and various coatings in paper manufacturing and printing processes.

• Construction & Mining: Reliable for pumping cement mortar, lime slurry, paints, mine tailings, and explosive slurries.
