Product Description
1. Revolutionary Operating Principle
The GAOTIAN GT-Lobe Pump operates as a self-priming, valveless positive displacement pump. Two synchronized rotors rotate in opposite directions within the pump casing, creating dynamic chambers that continuously transport media from inlet to outlet with near-zero pulsation.
The symmetrical design enables instant flow reversal by changing motor rotation direction – a critical feature for bidirectional applications like tanker loading/unloading.
2. Unmatched Technical Superiority
2.1 Extreme Media Compatibility
Engineered to handle:
High-viscosity fluids (e.g., crude oil up to 1,000,000 cP)
Abrasive slurries (≤30% solid content)
Shear-sensitive substances (pharmaceuticals, food products)
Gas-entrained liquids (up to 25% gas volume fraction)
2.2 Modular Rotor System
Interchangeable rotors with full material portfolio:
| Material Type | Key Properties | Applications |
|---|---|---|
| NBR Rubber | Oil resistance | Petroleum transfer |
| FKM Fluoropolymer | Chemical corrosion resistance | Acid/alkali solutions |
| PU Polyurethane | Ultra-wear resistance | Slurry pumping |
| 316L Stainless Steel | Hygiene & corrosion resistance | Food/pharma industries |
2.3 Zero-Leakage Sealing Technology
Multi-layered sealing solutions compliant with API 682 standards:
Single cartridge seals with self-lubrication for wastewater
Double cartridge seals with flush systems for hazardous chemicals
SiC/Tungsten carbide faces for lithium battery electrode slurry
3. Industry-Redefining Innovations
3.1 Maintenance Revolution
Patented quick-open cover enables full component access within 15 minutes without pipe disconnection, reducing downtime by 70%.
3.2 Energy Efficiency Leadership
Streamlined fluid path reduces hydraulic losses, achieving 15-20% lower power consumption vs. gear pumps at 5000 cP viscosity.
3.3 Pressure & Capacity Frontiers
Current maximum performance:
Flow rate: 3200 m³/h
Pressure: 2.5 MPa
5000 m³/h high-pressure models under development
