How to solve the problems of Split case pump -http://www.guomeipump.cn/Split-case-pumps.html

Trouble
After the pump starts, no water is sucked in, and the pointers of vacuum gauge and manometer beat heavily.
The pump doesn’t suck any water, but high vacuum is indicated on the vacuum gauge.
No water is pumped out, but high pressure is shown on the outlet manometer.
The flow rate is decreasing or the head is low. 
Over consumption of the pump power.
Unexpected noises are heard and no water is sucked.
The pump vibrates heavily.
The bearing is overheated.

reason
The water poured into the pump is not enough. Leakage of air is found the suction pipe. The foot valve is not opened. The resistance of suction is too high. The suction head is too high. The rotary direction is not right. The suction resistance is too high. The impeller flow channel is clogged. The number of revolutions is inadequate. The impeller flow channel or inlet pipe and outlet pipe are clogged. The seal ring or the impeller is worn out. The running speed of the pump is lower than the rated.
Packing is too tight and the impeller is rubbed by double suction seal ring. The flow rate is too large.
The suction resistance is excessive. The suction head is too high. Leakage of air is found from the suction pipe.
The impeller is not balanced The pump shaft is not concentric with the motor. The nuts of foundation are loose. The grease is not enough or too much or turns rotten. The pump and the motor shaft is not concentric.
Remedy
Pour water into the pump again. Block the leaking place. Open or renew the foot valves. Clean or renew the suction pipe. Make the suction head lower. Change the rotary direction. Check the length of the pipe. Clean the impeller. Increase the number of revolutions. Clean the impeller and pipes. Replace the worn parts. Increase the number of revolutions. Loosen the packing gland. Clear up the mechanic friction. Turn the discharge valve smaller. Check the pipe and the foot valve. Make the suction head lower . Block the leaking place. Adjust the discharge brake valve under specific working condition. Correct static balance of impeller. Correct the coaxial degree between pump and motor shaft. Screw the nuts of the foot bolts tightly. Check the bearing and replace the oil. Correct the coaxiality of the pump and the motor shaft
