Important Notes:
• For DFMSD medium-low pressure and high-temperature pumps: suction port pressure + maximum pump pressure ≤ 7 MPa
• For DFMSD medium-high pressure, abrasion-corrosion resistant, and seawater pumps: suction port pressure + maximum pump pressure ≤ 15 MPa
• DFMSD medium-low pressure pumps: temperature ≤ 105°C; external cooling water required when ≥ 80°C
• DFMSD high-temperature pumps: temperature ≤ 160°C; external cooling water and mechanical seal cooling flushing required
• For DFMSD medium-low pressure and high-temperature pumps: suction port pressure + maximum pump pressure ≤ 7 MPa
• For DFMSD medium-high pressure, abrasion-corrosion resistant, and seawater pumps: suction port pressure + maximum pump pressure ≤ 15 MPa
• DFMSD medium-low pressure pumps: temperature ≤ 105°C; external cooling water required when ≥ 80°C
• DFMSD high-temperature pumps: temperature ≤ 160°C; external cooling water and mechanical seal cooling flushing required
Structural Features
- Impeller and Shaft Balance: ISO 1940-1 G2.5 grade balanced for smooth rotation and vibration-free operation
- Heavy-Duty Bearings: Self-aligning radial spherical bearings and axial thrust bearings compensate for radial movement and withstand axial force
- Bearing Isolator: Prevents external contaminants, reducing bearing damage risk
- Flange Connection: GB/T 9124.1 PN series standard, other standards available
- Single-Stage Cover Bolt Structure: High-strength fine-pitch thread bolts minimize bending stress
- Equal-Load Design of Diaphragm Gasket: Balances radial force, reduces vibration and noise
- Transition Flow Passage: Optimized flow design minimizes friction loss and maximizes efficiency
- Split-Middle Throttle Bush: Withstands large axial and radial forces, simplifies rotor assembly
- Impeller Back-Pressure Device: Ensures balanced axial force, different vane numbers balance radial force
- Integrated Pressure-Equalizing Pipe: Packing seal only bears inlet pressure
- Sealing Gland: GB/T 14624.9 standard for reliable connection and easy maintenance
