Structural Diagram

| 1 | Motor | Directly coupled to the pump for power transmission. Uses branded motors (CYZ-A-L model adopts explosion-proof motors). |
| 2 | Pump Shaft | Coaxial with the motor. Features an extended shaft design ensuring concentricity for smooth operation (noise/vibration-free). Chrome-plated for enhanced durability. |
| 3 | Water Deflector Ring | Prevents motor flooding due to seal leakage. |
| 4 | Mechanical Seal | Constructed with stainless steel, tungsten carbide, and fluororubber. Balanced high-temperature/pressure-resistant design ensures leak-free operation, zero shaft wear, and no scale buildup. |
| 5 | Pump Cover | Connects the pump body and motor. |
| 6 | Pump Body | Designed with optimized hydraulic chambers (discharge/suction/gas-liquid separation). Features mounting feet for stable installation. |
| 7 | Impeller | High-efficiency hydraulic design for reliable performance. |
| 8 | Seal Ring | Seals the joint between impeller and pump body. |
| 9 | Bottom Cover Plate | Allows sediment removal when opened. |
| 10 | Drain Plug | Drains residual liquid during prolonged pump inactivity. |
| 11 | Baseplate | Provides structural connection and supports vibration isolator installation. |
| 12 | Discharge Nozzle | Connects to outlet pipelines. |
| 13 | Water Fill Valve | Replenishes cavity liquid when insufficient. |
| 14 | Check Valve | Prevents backflow upon pump shutdown. |
| 15 | Inlet Nozzle | Connects to intake pipelines. |
