Product Description
Slurry pump impeller
Naipu Impeller is one of the most important parts of slurry pump. When impeller is rotating, the slurry pump could meet the requirements of the equipment. However, it is a component, which is worn out very easily. Therefore, for long service life of the impeller, the material plays an important role here.
Naipu pump offers the two solutions for this problem. We choose the white iron, high chrome (27%) for the strong abrasive slurries, also with the sharp particles. For the corrosive slurries with blunt particles, we recommend the natural rubber.
Wear resistant cast alloys are used for slurry pump liners and impellers where conditions are not suited to rubber, such as with coarse or sharp edged particles, or on duties having high impeller peripheral velocities or high operating temperatures.
Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded elastomer impellers are completely interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
Metal impeller material
1) Material: A05,W1, W2, NA, Cr15Mo3, Cr24, Cr26, Cr27
R08, R24, R26, R33, R38, R66
2) Vanes from 3-6. It depending on the size of the particles in the slurry.
3) Impeller type including Close, Semi-open and Open type. Impellers are generally closed because of higher efficiencies and are less prone to wear in the front liner region. Open impellers are more common in smaller pumps or where particle blockage may be a problem or where the shear provided by an open impeller is an aid to pumping froth.
4) We can also produce the non-standard impellers for some special situations.
Pumping coarse coal
Pumping fibrous material
Reduced diameter impellers
Reduced eye impellers.

FAQ
Type AH(ZJ) series pump has a compact construction. If it is correctly installed and operated, the pump will have a long life.
| Faults | Reason | Removal |
| Pump fails to discharge any liquid. |
Air leaking into suction or gland Incorrect direction of pump rota- tion |
Sealed leakage. Check direction of rotation and replacing a new impeller. Removal lockage. |
| Shaft Power consumption is excessive |
Gland excessively tightened against packing rings. Rotating component is rubbing on a stationary part. |
Loosen gland bolts. Removal the rubbed part. |
| Bearing is over hearing | Lubricants too much or less. Containing impurities in the lubricant Bearing worn. |
Lubricating as requirements. Replace clean lubricant. Replace new bearing. |
| Bearing has short life. |
Misalignment or unparallel of drive Foreign object entered into the bearing or insufficient lubrication. |
Adjusting drive and pump shaft. Replacing shaft. Remove rubbing and replacing new impeller Clean the bearing. Replacing or refitting the bearings. |
| 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. |
Bearings worn. Impeller unbalanced. Air entered into suction pipe or blocked. Flow rate is none—uniform and pump not primed. |
Replaced by new bearings. Replaced by new impeller. Discharge air and remove block. Improve on the pump feeding. |
