Screw Pump

Characteristics of Positive Displacement Screw Pump
1. High reliability: Screw pumps have a simple structure and few moving parts, resulting in higher reliability due to fewer vulnerable components.
2. Long lifespan: The screw and liner of screw pumps are in solid contact, resulting in slow wear and a longer lifespan.
3. Stable flow rate: The flow rate of screw pumps is proportional to the rotational speed, resulting in a stable flow rate output.
4. Strong adaptability: Screw pumps can adapt to liquids of various viscosities and temperatures, and even liquids containing impurities and particles.
5. Low noise: Screw pumps operate with minimal vibration and smooth operation, resulting in low noise.
6. Easy maintenance: Screw pump components are easy to replace, making maintenance convenient and operation easy.

Industries where Stainless Steel Industrial Pulp Pump is applicable include:

• Papermaking Industry: Used for the circulation, lifting, and pressurization of media with a concentration below 6% in pulp conveying and alkali recovery industrial processes.
• Sugar Industry: Utilized for conveying syrup with a concentration below 4% and a viscosity below 150mm2/s.
• Urban Sewage Industry: Employed for the circulation, lifting, and pressurization of media in wastewater treatment processes.

G series is progressive cavity screw pump(single screw pump. It belongs to the group of rotary positive displacement pumps. Progressive Cavity Pump is used in almost industry sectors for conveyance and dosing of various media. Preferably, media with or without solids having low to very high viscosities conveys. However, it is also suitable for conveying aggressive media, such as the ones used in paper making, waste water treatment or brewery.

The Progressive Cavity Screw Pump was first developed and successfully applied in Peru in the 1960s, initially used for catching fish and shrimp. In order to prevent solid substances from clogging and ensure smooth outflow, a twisted screw blade is installed in the impeller. Along the axial extension of the conical wheel hub from the suction port, the radius of the flow channel gradually increases, forming a helical flow passage. Building on the original design, advanced production techniques from leading enterprises were introduced to further improve the pump. In addition to the original belt pulley transmission method, a new shaft-coupled transmission method was developed, expanding the pump's application range. After years of market promotion, it has been widely used in industries such as papermaking, fishing, sewage treatment, gelatin processing, food processing, and chemical engineering.

Mono Screw Pump Manufacturers Characteristics:
Wide range of conveyance: It can effectively transport materials with solids content up to 60% and viscosity as high as 1,000,000 CPS.
Low mechanical vibration and noise: There is no stirring, shearing, turbulence, or agitation of materials during operation.
Strong self-priming capability: The suction lift can reach up to 8.5 meters (28 feet).
Special structure composed of a rigid rotor and an elastic stator enables it to transport materials containing solid particles.
The maximum temperature of the conveyed material can reach up to 120 degrees Celsius, with a maximum flow rate of 260m3/h. The pressure can reach 9.6 MPa.
The flow rate is linearly related to the speed, making it convenient to control the flow rate by adjusting the speed. It is commonly used as a metering pump.
