Slurry Pump Little Tips Collection
1: The simple way to distinguish between vertical slurry pump and submerged slurry pump is to have 4 and 3 bolts respectively
2. Fractional series slurry pumps below 4/3-MAH include 4/3-MAH pump with only one guard plate
3. The submerged slurry pump can be equipped with a mixing wheel, which is conducive to extracting uniform slurry
4. The rear plates of 100ZJ-42 and 80ZJ-42 can be interchanged
5. Slurry pump coupling belongs to column pin elastic coupling
6. The hardness of the flow passage parts of the slurry pump is not better if it is larger, but it is better to control it between 58-62
7. Cutting impeller can adjust the flow of slurry pump
8. ZJ type slurry pump can not be connected in series at multiple stages, because the pressure design is small
9. ZGB and fraction series slurry pumps can be multi-stage in series
10. The lift of the slurry pump is about 120m
11. The material of slurry pump is not only Cr27, but also more suitable material can be changed according to specific working conditions
12. The normal applicable medium PH range of wear-resistant white cast iron Cr27 is 5-13
13. The joint between the front and rear guard plates of ZJ series slurry pump and the volute adopts (5) degree taper fit
14. The recommended range of flow relative to design flow during model selection is (60% - 125%)
15. When conveying strong abrasive media, the relationship between the speed and the life of flow passage components is (the speed is inversely proportional to the life)
16. Sharp particles have great wear on flow passage parts
17. The material Cr27 used for slurry pump has better performance in (alkaline) environment.
18. (Steep drop) performance curve is conducive to selection of slurry pump
19. The specification gives the large particle size value that is allowed to pass intermittently. Generally, the normal particle size value is (56%) of the large particle size value that is allowed to pass intermittently
20. The slurry velocity of the pump in the outlet pipeline must be (greater than) the slurry settling velocity, otherwise the pipeline will be blocked.
21. When the slurry pump is arranged in a high position (reverse flow), the water inlet pipe of the pump should avoid steam cavitation. It is recommended to use a horizontal reducer pipe (upper busbar).
