Quantity
Designed for high-viscosity fluids and gas-containing media in petrochemical, food, and pharmaceutical industries, the stainless steel pump solves pulsation control and self-priming challenges. Featuring a screw pump mechanism with zero-pulsation conveying, 5m self-priming height, and a direct-connected compact structure, this pump stainless steel model suits DN25-DN100 pipelines, delivering stable, cost-effective performance for sensitive media and harsh conditions.
Core Advantages
- Strong self-priming ability, simplified installation
With optimized gas-liquid separation chamber design, the self-priming height is up to 5 meters, which is suitable for residual gas in pipeline or intermittent operation scenarios.
- Directly connected structure design, long-lasting and stable
The motor and screw pump body are directly connected through the flange, eliminating the traditional coupling and independent bearing seat, reducing the risk of mechanical loss and increasing the operating efficiency by 15%.
- Low pulsation conveying, zero media damage
Screw - liner precision mesh design, conveying process without pulse, no shear, to ensure the integrity of high-viscosity fluids, containing fragile solid media.
Technical Highlights
- Wide Temperature Range Adaptation
The medium temperature ranges from -30℃ to 180℃, covering frozen concentration to high-temperature steam condensate scenarios;
- Seal reinforcement options
Standard single-end mechanical seal, optional double-end, cartridge seal, pressure resistance level up to 1.6MPa;
- Intelligent Load Adaptation
Built-in adaptive torque adjustment system can automatically match the motor output power according to the viscosity of the medium and pipeline resistance, avoiding light load consumption or overload damage.
Application Scenarios
- Petrochemical
Circulation transportation of thick oil, polymer solution, slurry containing catalyst;
- Food and Pharmaceutical
Pollution-free transmission of fruit pulp mixtures, fermentation liquids, and ointments;
- Environmental engineering
Efficient discharge of fiber-containing sludge, sedimentation waste;
- Shipbuilding industry
Ballast water treatment, bilge oil sewage recovery.
