**Product Overview:**
The 1-1B series pump is a closed-type screw pump with an internal gear design, classified as a rotor pump. It is ideal for handling various types of media, including high-viscosity liquids, suspensions, solid particles, and fibrous materials. With stable flow, excellent suction capability, and minimal pressure fluctuations, it offers reliable performance in a wide range of industrial applications.
**Key Features:**
- Suitable for high-viscosity fluids (up to 200,000 cP)
- Food-grade rubber stator for safe and hygienic operation
- Stainless steel rotor for durability and corrosion resistance
- Gentle mixing action that preserves the structure of transported solids
- Low noise level during operation
- Continuous and steady pressure output without periodic fluctuations
**Applications:**
This pump is widely used in industries such as mining, environmental protection, marine, petroleum, chemical, food processing, pharmaceuticals, brewing, construction, printing, papermaking, power generation, and boiler systems.
**Working Principle:**
The single-screw pump operates using an eccentric screw (rotor) and a static bush (stator). Due to its unique geometric shape, it forms multiple sealed cavities that continuously and evenly transport the medium from the suction side to the discharge side.
