Start, running and stop 

Start

1. First of all, pour water into pipes, to make the pump and inlet pipe filled with water. The pipes shall be sealed, no air leaked. (no-water inside start is forbidden) 
2. Close globe valve and cock on outlet pipe, to reduce start currency.
3. Rotate the rotor by hand, lubricate the bearing and check the pump impeller, seal the ring, if it cannot rotate, you shall not start.
4. Try to start, motor rotation direction shall be as same as the arrow direction on the pump. 
5. When the rotor works normally, open gradually the outlet globe valve, adjust for the work conditions required.

Running

1. Observe the reading in meters, keep it running around the flow and head shown on the nameplate.
2. Regularly check, motor currency value shall not exceed rated currency value.
3. Pump bearing temperature shall not exceed 75ºC, and shall not be 35ºC higher than ambient environment.
4. To start, loosen the stuff cap. Adjust later when started.
5. In case of fragile component abrasion, replace in time.

6. When any abnormal happens, immediately stop and check.

Stop

1. Close the globe valve on the outlet pipe, close the vacuum gauge cock.
2. Stop the motor, and close the pressure cock.
3. In Winter, drain the liquid in the pump completely to avoid frozen cracks.
4. When you will not use it for a long time, uninstall the pump, clean, and lubricate.


Troubleshooting 
 

Fault	Cause	Solution
The pump cannot suck water, pressure gauge & vacuum gauge vibrating	1. Insufficient water pouring  2. Leak between pipe and meter  3. Suction is too high	1, check a leak in the bottom valve.  2, Tighten the leaked part  3, reduce suction
The pump cannot suck, high vacuum is shown in the vacuum gauge	1, bottom valve closed or jammed  2, Too great water suction resistance  3, filter jammed	1, check bottom valve 2, replace water suction pipe 3, clear off the filter
Pressure gauge works, no water outcome	1. Great outlet water pipe resistance 2. Wrong rotation direction  3. Outlet pipe valve closed 4. impeller jammed	1. check or shorten water pipe  2, check the motor, adjust  3, open the valve and clear off the impeller
Cannot reach designed flow	1. air sucked  2. Water level drops, submerged depth is not enough  3. impeller jammed  4. rotor torn and worn	1, check leak part and clear off  2, prolong water inlet pipe, increase the submerged depth 3, uninstall and clear off  4, replace seal ring
Great pump power consumption	1. Stuff tightened, overheated  2. Great flow  3. Collision between rotor and case  4. Pump shaft bearing abrasion  5. Pump shaft misplaced	1. loosen slightly 2. reduce globe valve opening 3. adjust  4. replace bearing  5. replace or adjust
Great pump vibration	1. impeller partially jammed  2. impeller damaged  3. little flow  4. non-concentric between pump shaft and motor. 5, bearing damaged  6, gas etching	1. Uninstall and clear off  2, replace  3, increase opening  4, adjust 5, replace   6, change suction inlet port
