NZJ-Sequence Slurry Pumps
1. Employs and Attributes:
NZJ-Collection slurry pumps are suited for pumping slurry with hard particles and in high density in industrial sectors as of metallurgy, mining, coal, electrical power generation and developing material. These pumps can also be used multi-staged in collection. They are classified into a few kinds: M. AH. HH.

The M. AH. HH sort slurry pumps are individuals of cantilever, horizontal and centrifugal slurry pumps, whose shafts can be sealed by packing seals or by centrifugal variety seals. The positions of the pump outlet can be positioned at an interval of 45° According to various demands, so eight different angles can be applied by rotation in installation.

The M. AH sort slurry pumps have pump bodies (volute liners, entrance and back liners) that consist of replaceable put on-resistant steel liners or wear-resistant rubber liners, and impellers can also utilize put on-resistant steel materials or dress in-resistant rubber material. The HH type slurry pumps only utilize dress in-resistant metal materials as their pump bodies and impellers.

3. Structural Picture:
NZJ-Series slurry pumps are ideal for extreme slurry conditions with coarse particles and substantial competency.
3.one There are two types of content for wet areas (volute liners, entrance and back liners, impellers):
L Manufactured of higher-chrome alloy material
L Created of highly wear-resistant rubber material researched and produced by CZPT company.
Both of them can fulfill the process of slurry pumping with high performance and prolonged provider daily life.
3.two Structure of shaft seals:
L Packing gland seals
L Strain-minimizing metal gland seals
L Stress-minimizing rubber gland seals
L CZPT seals.
NZJ Sequence slurry pumps have two kinds of structural modes, which are the large-chrome alloy a single and the rubber use-resistance 1. The wet elements created of both alloy or rubber can be mixed up in operation.

For case in point: A rubber volute liner and liners can be mixed with an alloy impeller in procedure, and a rubber impeller can be utilized collectively wit an alloy volute liner and liners.

four. Introduction of Type Selection
When the kind assortment is carried out, the efficiency curve desk for very clear drinking water of a pump shall be referred to, and the coefficient of variety for the flow selected is as follows:

4.one M, AH type pumps
4.1. 1 For slurry of higher density and sturdy abrasiveness, the coefficient of flow selection will be forty-eighty%
four.1. 2 For slurry of medium density and medium abrasiveness, the coefficient of stream range will be forty-100%
four.one. three For slurry of low density and minimal abrasiveness, the coefficient of stream assortment will be forty-120%.

4.2 HH variety pumps
four.two. 1 For slurry of medium density and sturdy abrasiveness, the coefficient of movement variety will be forty-eighty%
four.two. 2 For slurry of minimal density and powerful abrasiveness, the coefficient of movement variety will be 40-a hundred%
4.two. 3 For the highest efficiency point beneath a specific RPM problem, its corresponding movement fee will be a hundred%.
