Product Introduction of ISG, ISW single-stage single-centrifugal pump
ISG series vertical single-stage single-suction centrifugal pump is a new generation of energy saving, environment friendly vertical centrifugal pump researched and developed by our company, which absorbs advanced technology of similar products abroad and adopts domestic general performance parameters of centrifugal pumps. In addition, according to different operation temperatures and mediums, we developed the hot-water pump (IRG), corrosion-resistant chemical pump (IHG) and oil pump (YG). This pump enjoys excellent performance, good reliability, long operation life, reasonable construction and nice appearance, which is outstanding in the industry.

1. Vertical



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

1. Application Scope
Deliver fresh water or the liquid which its chemical character is similar to fresh water. Industry and city water supply and drainage.

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.
