1. Pump Body: to lower the velocity of flow, making velocity energy into pressure energy.
2. Impeller: to play a leading role with its vane forcing liquid rotated and splashed around driven by centrifugal force.
3. Pressure Plug: to mount pressure gauge to monitor the normal operation of pump.
4. Air Release Valve: to release the air inside to ensure the normal start of pump.
5. Y/Y2 Series Motor: the driving part of pump, with a close coupled type.
6. Base: pump’s foundation, to ensure the stable of installation.
7. Water Deflector: to avoid water entering motor due to leakage at seal.
8. Pump Cover: elaborately designed of sharing the same end cover with motor, shortened axial dimensions and simple structure.
9. Mechanical Seal: made of stainless steel, tungsten carbide, fluorine rubber and etc, for outstanding sealing, durable service life and leak-tightness.
10. Pump Shaft: coaxial with motor and high concentricity to enable pump operating without noise and vibration.
11. Drain Plug: fully let out the liquid inside in case that pump needs servicing or will be left unused for a long time.

1. Application scope  

Transporting clean water or weakly corrosive liquids without solid particles and fibers (wearing parts use stainless steel)
Construction
High-rise water supply, building fire protection, central air-conditioning water circulation
Industry
Circulation and cooling systems, boiler water supply and industrial water supply and drainage in industrial process systems.
Water supply
Water plant water supply, distribution and supercharging, artificial landscape water supply boosting, plantation irrigation, etc.

2. Using Instruction
Before start:
1. Turning the clutch by hand, there should be no jammed phenomenon at the turner position.
2. Opening the inlet valve and the vent valve, letting the water fill into the pump's chamber, then closing the vent valve.
3. Clicking the switch of motor, and confirming whether the turning is right or not.
Running:
1. Fully opening the inlet valves, and closing the valves of the outlet pipe.
2. Connecting the power, Opening the valves of the outlet pipe and adjusting the needed working point when the turning velocity is normal.
3. Watching whether there exist abnormities or not, if yes, should the pump be stopped and inspected before re-running.
Stop:
1. After turning off the outlet valves one by one, shutting off the power.
2. Shutting off the inlet valves.
3. If the ambient temperature is below 0, some warm keeping measures should be adopted.
