Feature and Application

 

12/10 G-G   Sand  and Gravel Suction Pump  are designed for continuously handling the most abrasive and corrosive slurries which contain too big  particles  to be pumped by a common pumps. They are suitable for delivering slurries in mining explosive-sludge in metal melting dredging in dredger and course of rivers and other fields. 

Structure of this pump is of single casing connected by means of clamp bands and wide wet-passage. The wet-parts are made of ni-hard and high chromium abrasion-resistance alloys. The discharge direction of pump can be oriented in any direction of 360°. This type of pump possesses the advantages of easy installation and operation good performance of npsh and abrasion resistance.

Typical Applications---

Slag Granulation
Suction Hopper Dredging
Dredging
Barge Loading
Sand Reclamation
Sugar Beet

 Possible Faults And Removal

Faults	Reason	Removal
Pump fails to discharge any liquid	Air leaking into suction or gland Incorrect direction of pump rotation & impeller worn Suction pipe blocked	Sealed leakage Check direction of rotation and replacing impeller  Removal blockage
Shaft power consumption is excessive	Gland excessively tightened against packing rings Rotating component rubbing on a stationary part Bearing worn Drive belt tension too tight  Flow rate too large Pump speed and ratio too high Misalignment or unparallel of drive shaft and pump shaft	Loosen gland bolts Removal the rubbed part Replace the bearing Adjusting belt Modifying the pump duty and speed Adjusting drive and pump shaft
Bearing is over heating	Lubricants to much or less Containing impurity in the lubricant  Bearing worn	Lubricant as requirement Replace new lubricant Replace new bearing
Bearing has short time	Misalignment or unparallel of drive and pump shaft Shaft bent Impeller unbalanced due to wear Foreign object entered into the bearing or insufficient lubrication Incorrect procedure followed in fitting bearing	Adjusting drive and pump shaft Replacing shaft Removal rubbing and replacing new impeller Clean the bearing  Replacing or refitting the bearing
Excessive leakage from stuffing box	Packing rings excessive worn Shaft sleeve worn Dirty sealing water	Replace new packing rings Replace shaft sleeve. Change clean sealing water
Pump vibrates Or is noisy	Bearing worn  Impeller unbalanced Air entered into suction pipe or blocked Flow rate no-uniform and pump not primed	Replace by new bearing  Replace by new impeller Discharge air and remove block Improve on the pump feeding.
