KSB ETNY / SYT High Temperature Thermal Oil Pump Product Features and Design Advantages
1. High-Temperature Reliability
The pump body is designed with a 3.2 mm corrosion margin to ensure long-term durability under high-temperature conditions.
The entire pump adopts a self-heating heat dissipation structure, eliminating the traditional water cooling system, resulting in
a more compact structure, reduced operating costs, and reliable operation.
2. Advanced Sealing Technology
Utilizes mechanical seals conforming to DIN 24960 / EN 12756 standards.
Single-end or double-end mechanical seals are available depending on operating conditions.
The sealing structure is optimized for high-temperature hot oil conditions, ensuring leak-free operation.
3. High-Efficiency Hydraulic Design
Closed radial impeller with multi-curvature blades for high fluid efficiency.
The impeller is dynamically balanced for smooth and quiet operation.
Single-suction impeller design meets high flow rate requirements.
4. Reliable Bearing System
The pump end uses product-lubricated carbon graphite sliding bearings (more stable under high-temperature conditions).
The drive end uses grease-lubricated radial ball bearings.
Meets API vibration and shaft seal flushing specifications.
5. Flexible Configuration Options
Standard configuration: Flexible coupling + coupling cover + common base.
ATEX explosion-proof type optional (suitable for hazardous areas).
Optional variable frequency drive (PumpDrive) system for variable flow rate operation and significant energy savings.
