Plenty inventory of slurry pump parts. Not only for the below shown rubber liners, but also for metal pump parts such as impellers, volute liners, and so on. 
What we can guarantee is a swift delivery to minimize the customers' down time.

At CNSME, you'll find a wide inventory of pumps and parts that are 100% interchangeable with the world's most recognized slurry pump brand. We stock many spare parts to cut down on downtime when repairing your equipment. We guarantee a swift delivery time both on the bare shaft complete pumps and spare parts for replacements.

During operation, there are four types of common failures of slurry pumps: corrosion and abrasion, mechanical failure, performance failure and shaft sealing failure. These four types of failures often affect each other.
For example, the corrosion and abrasion of the impeller will cause performance failure and mechanical failure, and the damage of the shaft seal will also cause performance failure and mechanical failure.
1. Bearings Overheated
A. Too much, too little or deterioration of lubricating grease/oil will cause the bearing to heat up, and the appropriate amount and quality of oil should be adjusted.
B. Check whether the pump -motor unit is concentric, adjust the pump and aglign it with the motor.
C. If the vibration is abnormal, check whether the rotor is balanced.
2. Reasons and solutions that may causenon output of slurry
A. There is still air in the suction pipe or pump, which should be filled with liquid to discharge the air.
B. The valves on the inlet and outlet pipeline are closed or the blind plate is not removed, then the valve should be opened and the blind plate removed.
C. The actual head is higher than the maximum head of the pump, a pump with higher head should be employed
D. The rotation direction of the impeller is wrong, so the rotation direction of the motor should be corrected.
E. The lifting height is too high, which should be lowered, and the pressure at the inlet should be increased.
F. The debris is blocked the pipe or the suction pipeline is small, the blockage should be removed and the pipe diameter should be enlarged.
G. The speed does not match, which should be adjusted to meet the requirements.
3. Reasons and solutions for insufficient flow and head
A. The impeller is damaged, replace it with a new impeller.
B. Too much damage to the sealing ring, replace the sealing ring.
C. The inlet and outlet valves are not fully opened, they should be fully opened.
D. The density of the medium does not meet the requirements of the pump, re-calculate it.
4. Reasons for serious seal leakage and solutions
A. Improper selection of sealing element materials, replace suitable elements.
B. Serious wear, replace the worn parts and adjust the spring pressure.
C. If the O-ring is damaged, replace the O-ring.
5. Reasons and solutions of motor overload
A. The pump and engine (output end of the motor or diesel engine) are not aligned, adjust the position so that the two are aligned.
B. The relative density of the medium becomes larger, change the operating conditions or replace the motor with suitable power.
C. Friction occurs in the rotating part, repair the friction part.
D. The resistance (such as pipeline friction loss) of the device is low, and the flow will become bigger than required. The drain valve should be closed to obtain the flow rate specified on the pump label.

Slurry pump in the process of conveying large concentration of mud for blocking solutions: 1 In the case of ensuring the main design parameters (flow, head) unchanged, the impeller can be changed from the original closed impeller to semi-open impeller. 2. Redesign the hydraulic model. 3. Redesign the front guard plate to match the newly designed impeller.
